GENERAL PRECAUTIONS REGARDING THE INSTALLATIONAND SERVICE FOR THE COPIER 2060, 2860/70 AND THEAUTOMATIC DUPLEXING UNIT MD-5002

1. Transportation/Installation

• When transporting/installing the copier, use two persons and be sure to use the positions as indi-

cated below.

The copier is fairly heavy and weighs approximately 73 kg (161 lb), therefore pay full attention

when handling it. (2870: 84 kg)

4 portions

2. Installation

• Be sure to use a dedicated outlet with AC 115V/15A (220V, 240V/10A) or more for its power

source.

• The copier must be grounded for safety.

Never ground it to a gas pipe or a water pipe.

• Select a suitable place for installation.

Avoid excessive heat, high humidity, dust, vibration and direct sunlight.

• Also provide proper ventilation as the copier emits a slight amount of ozone.

• To insure adequate working space for the copying operation, keep a minimum clearance of 80 cm

(32”) on the left, 80 cm (32”) on the right and 10 cm (4”) in the rear.

3. Service of Machines

• Basically, be sure to turn the main switch off and unplug the power cord during service.

• Be sure not to touch high-temperature sections such as the exposure lamp, the fuser unit, the

damp heater and their periphery.

• Be sure not to touch high-voltage sections such as the chargers and the high-voltage transformer.

• Be sure not to touch rotating/operating sections such as gears, belts, pulleys, etc.

• When servicing the machines with the main switch turned on, be sure not to touch live sections

such as the lamp terminal, etc.

• Use suitable measuring instruments and tools.

4. Main Service Parts for Safety

• The breaker, door switch, fuse, thermostat, thermofuse, thermistor, etc. are particularly important

for safety. Be sure to handle/install them properly.

5. Notice Labels

• Be sure to check the rating plate and the cautionary labels such as “Unplug the power cord during

service”, “Hot area” etc. to see if there is any dirt on their surface or if they are properly stuck to the

copier during servicing.

6. Disposition of Consumable Parts/Packing Materials

• Regarding the recovery and disposal of the copier, supplies, consumable parts and packing mate-

rials, it is recommended to follow the relevant local regulations or rules.

7. When parts are disassembled, reassembly is basically the reverse of disassembly unless

otherwise noted in this manual or other related documents. Be careful not to reassemble

small parts such as screws, washers, pins, E-rings, toothed washers in the wrong places.

8. Basically, the machine should not be operated with any parts removed or disassembled.

9. Precautions Against Static Electricity

• The PC board must be stored in an anti-electrostatic bag and handled carefully using a wristband,

because the ICs on it may become damaged due to static electricity.

6 Separation : Separates the transfer sheet,

along with the toner, from the

drum.

7 Fixing : Fixes the toner on the transfer

sheet by applying heat and

pressure.

8 Cleaning : Mechanically removes any re-

maining toner on the drum.

9 Discharge lamp : Discharges any remaining

charge from the drum.

1 Charging : Negatively charges surface of

the photosensitive drum.

2 Exposure : Forms an electrical image on

the drum.

3 Development : toner adheres to surface of

photosensitive drum and forms

a visible image.

4 Transfer bias : Increases transfer efficiency.

5 Transfer : Transfers the visible image from

the drum onto the transfer

(copy) sheet.

5.4 Description of Operation5.4.1 Dot matrix LCD display circuit

(1) Structure

• Dot matrix LCD display circuit has a display ca-

pacity of 40 characters (20 characters x 2 lines).

• 1 character is a unit consisting of ON/OFF lights

made of 35-element (5 x 7) dots.

(2) Drive Operation

• LED control: The LCD’s internal control driver drives.

• What character is displayed in what position: IC19 (main CPU), IC9 (HC244), IC37 (7407), and

IC18 (gate array) of the logic circuit control.

• Message data and executable programs are stored in the main PROM.

• The character codes are stored in the PROM on the LCD.

The main CPU divides the display block into 4 blocks. The main CPU outputs the RAM address data

for the starting position at which each block is displayed and then outputs display data for the number

of characters (10 characters) to be displayed to the LCD. When the message is changed, the main

CPU outputs the display data for the blocks 1~4.

3 4 (4a)

Display blocks

When changing the display data only for the repro-

duction ratio, the leading RAM address data in the

display position of the reproduction-ratio block (4a)

are first output and then the display data for the

number of reproduction-ratio characters (4 char-

acters) are output to the LCD.

5.4.2 LED display circuit

(1) LED display method

For example, the following shows how the LED LP12 (APS) lights up for displaying “automatic paper

sensing”.

When DSPON0 signal becomes “L” level, transistor Q2 is turned ON. Further, when IC4 pin14 (D10)

becomes “L” level, current flows from +5VD to LP12 (APS) through the transistor. In this way LP12

(APS) lights up.

(2) The actual circuit is controlled as follows.

Condition of LED lighting

1 The transistor (Q1 or Q2) connected on the anode side of the LED is ON status.

2 Output connected on the cathode side of the LED is “L” level.

When the above conditions 1 and 2 are fulfilled, the LED lights.

Refer to the following names of the LED which are ON/OFF controlled by DSPON0/DSPON1 signals.

• The signals of DSPON0 and DSPON1 be-

come “L” level by one turn every 8 msec.

• Q1 (or Q2) is turned ON when DSPON0 (or

DSPON1) is “L” level.

• LED ON/OFF signal from LGC is inputted

to the SIN (pin 26) terminal of IC4 through

DSPDAT signal line. (Serial data)

• The LED ON/OFF signal is inputted to IC2

in serial is outputted to output terminals of

D1 – D16 in parallel.

8Controlsignal

(1) The LGC transmits control signals for main motor rotation. (MAIN-CW/CCW: Direction of rotation,

MAINMOT-ON: Motor rotation command)

(2) The excited phase switching unit excites each phase on the main motor → Main motor runs.

(3) Hall elements A to C are used to detect the rotation position of the motor (or rotor).

(4) The excited phase switching unit switches the excitation for each phase.

(By repeating (2) through (4) above, the motor keeps running.)

(5) The FG pulse is generated by the FG pulse pattern and N/S magnets of rotor installed on the main

motor.

(6) The phases and velocities of the FG pulse and the reference frequency from the LGC are com-

pared, and the differences are added. Further to this are added the fluctuations in the supply volt-

age. (Signal generation)

(7) Changes the switching timing for the excited phase switching unit to match the signal amount ob-

tained in step (6).

i.e. control is done to equalize the FG pulse and reference frequency. → The main motor runs at a

constant speed. (Locked range state.)

(8) When the main motor enters the locked range state, the excited phase switching unit transmits the

PLL-OK signal to the LGC. (“L” level).

(9) When the MOT-BRK from LGC enters “L” level, the main motor rotation is braked, and when the

MAINMOT-ON signal enters “H” level, the main motor stops.

6.4.2 Control signals

(1) MAIN-CW/CCW signal (LGC → MOT: Input)

Switches the rotation direction of the main motor. When this signal becomes “L” level, the main

motor rotates counterclockwise as viewed from the rear side, and drives the developer unit, drum,

heat roller, etc.

(2) PLL-OK signal (MOT → LGC: Output)

When the cycle of FG pulse deviation from the reference frequency is within fixed range, this state

is specified as lock range (normal rotation), and this PLL-OK signal becomes “L” level. Also, at this

time, the LED “LP1” light comes on.

(3) F-MOT-REF signal (LGC → MOT: Input)

This signal is a reference clock signal for the main motor to rotate at a fixed speed.

(4) MOT-BRK signal (LGC → MOT: Input)

When it becomes “L” level, the main motor rotation is broken down.

(5) MAINMOT-ON signal (LGC → MOT: Input)

This signal is main motor ON/OFF control signal, when it becomes “L” level, the motor rotates.

7. OPTICAL SYSTEM7.1 FunctionsIn this copier, the surface of the original is directly exposed to light, and the reflected light is conducted to

the surface of the drum via the mirror, lens, and slit.

The whole original image is reflected on the drum surface through the light source being scanned from

the leading edge to the trailing edge.

This area where functions as above are performed is called the optical section, located at the upper side

of the copier.

7.2 ConstructionThe construction and purpose of the optical section are the followings:

(1) Original glass

The original is placed on this glass. Light from the exposure lamp exposes the surface of the origi-

nal through this original glass.

(2) Carriage 1

Carriage 1 consists of the exposure lamp, reflector, mirror 1, thermofuse, and light distribution

adjustment plates, etc. Carriage 1 is scanned by the scanning motor. The relation between the

scanning speed and the drum rotation speed is specified as follows. In actual-size copying, both

speeds are the same. The reproduction ratio of the direction of paper transport (lengthwise repro-

duction ratio) is specified by this scanning speed being changed. In enlargement copying, the scan-

ning speed is slower than the drum rotation speed, and in reduction copying it is faster.

d. Thermofuse

Prevents the exposure lamp from an increase in temperature due to excessive lighting.

e. Light distribution adjustment plates

It is positioned to shield the light irradiated from the reflector on the surface of original, and adjusts the

light intensity.

If the positions for the installation of this adjustment plate at the front or rear side are shifted, and the

light intensity is different at both sides, this may cause uneven light distribution.

(3) Carriage 2

Consists of mirror 2 and 3, conducts the reflected light from mirror 1 to the lens via mirror 2 and 3.

This is also scanned by the scanning motor in the same way as carriage 1.

The scanning speed is half that of carriage 1.

(The scanning distance is also half.)

(4) Lens unit

It is driving by the lens motor. The reflected light from mirror 3 is reversed at the lens focus, and

conducted to mirror 4 (mentioned later).

Lens

Lens unit

(5) Mirror unit

The mirror unit consists of mirror 4 and 5, and conducts the reflected light passing the lens to mirror

6 via mirror 4 and 5. This is driven by the mirror motor. Changing of positions of the lens unit and

mirror unit alters the reproduction ratio of the vertical direction of paper transport (lateral reproduc-

tion ratio).

When the distance of the light path is equal between the original surface and the lens focus and the

lens focus and the drum surface, actual-size copying is obtained.

When the former is longer, reproduction copying is performed, and when shorter, enlargement

copying.

from toner dust, etc.

(8) Copy-area indicator unit

This is located inside the original scale. This is for indication of the maximum area in which the copy

can be made at that time.

The indicator is driven by the document motor. The original range is indicated with the copy-area

indicator and orange line on carriage 1.

7.3 Description of Operation7.3.1 Scanning motor

The scanning motor rotation is transmitted to carriages 1 and 2 via the timing belt and the carriage drive

wire. Carriage 1 and 2 are first moved to home position. The home position is detected when carriage 1

passes the home switch. When the PRINT key is pressed, carriages 1 and 2 scan the original.

Immediately after the power is switched on:

• If the lens/mirror switch is on, the lens unit is transported to the exit side. Then the mirror unit is

transported to the feed side, and it is positioned for actual size copying.

• If the lens/mirror switch is off, the switches are turned on by the lens unit, then the mirror unit in that

order and both units are positioned for actual-size copying.

When the reproduction ratio is selected, the lens unit and the mirror unit are positioned accordingly using

the actual-size position as the starting (standard) position.

7.3.3 Document motor

The front and rear copy area indicators are set at home position, that is, for maximum width, via the

timing belt. When the paper size or reproduction ratio is changed, the indicators are positioned for the

specified size and the original setting position is indicated on the glass.

7.3.4 Optical fan motor

Stops during standby and rotates during copying, and cools the optical section.

7.4 Pulse Motor Drive7.4.1 Pulse motor drive circuit (constant current type)

The scanning motor (M2) is driven by hybrid IC STK6713BMK4 of the unipolar constant current chopper

drive. The driving circuits of A and A phases are shown below. Since B and B phases are exactly the

same, they are omitted here.

The circuit configuration on the inside of the IC is composed of each phase excitation switching section

(IC2), driver (F1, F2), comparator (IC1), and current detection resistor (R7).

The following explains the circuit operation when the A phase is excited.

– Process when the A phase is excited –

1 øA phase becomes “L” level (øA is “H” level).

2 Reverse input E of the comparator (IC1) is applied the reference voltage which depends on the

resistance divided voltage of the R51, R55, and the R58.

Non-reverse input B is “L” level. Therefore, the output C of IC1 becomes “L” level.

3 According to step 1 and 2, D of IC2 becomes “H” level, and F1 is turned ON. (conductive condi-

tion).

4 Current flows into the coil A from the power supply of +24V, and it gradually increases.

5 The terminal voltage of the current detection resistor R11 increases, and C becomes “H” level and

F1 goes OFF from the moment when voltage B becomes higher than voltage E.

6 Because the winding method of coil A and A is bipolar winding, the energy stored in coil A is induced

in coil A, and is discharged using the coil A.

That is, A current flows in direction of DG (Drive Ground), R7, F2 diode and coil A.

7 When the voltage stored in the condenser C1 lowers, and becomes lower than voltage E , C

becomes “L” level and F1 comes ON again, and winding current of A phase increases.

8 In this manner, the ON/OFF operation of the motor current (constant current chopping operation) is

repeated.

Motor input current waveform

In the case of the excitation of A phase, øA becomes “L” level and F2 comes ON, the same operation is

performed.

The limit of winding value is changed in high torque and low torque by the D/A output. In low torque the

current is lower, in high torque the current is higher.

Low torque : IOH

= 1.0 – 1.15 (A)

High torque: IOH

= 1.25 (A)

7.5 Exposure Control Circuit7.5.1 Introduction

The exposure control circuit is composed of four blocks as follows.

1 Lamp regulator Applies a pulse duty ratio corresponding to PWM signal

to the exposure lamp.

2 Automatic exposure sensor circuit Generates an AES signal indicating the density of the

original by sensing the light reflected by the surface of

the original.

3 Exposure step Detects the exposure position set by the operator’s key

input

4 Arithmetic and control unit Determines the lamp voltage by computation on the

basis of AES and exposure step, and outputs the PWM

signal to the lamp regulator.

Note : The ON/OFF state of the exposure lamp is controlled by a special signal (EXPON; J2-A18),

distinct from the PWM signal.

The exposure control circuit has the following two functions:

A Manual exposure mode ..................A constant lamp voltage corresponding to the set exposure

step on the exposure lamp is applied.

B Automatic exposure mode ..............The quantity of light reflected by the surface of the original,

which varies infinitely with the lightness and darkness of

the surface of the original, is detected by the automatic ex-

posure sensor circuit, and the voltage applied to the expo-

sure lamp is continually varied accordingly; a high lamp

voltage being impressed for dark originals and a low lamp

voltage for light originals.

7.5.2 Operation of lamp regulator

A typical characteristic curve is shown in the following diagram.

By means of a phase-angle control system, a lamp voltage corresponding to the PWM pulse duty

ratio input is generated even if some fluctuation occurs in the AC input voltage.

7.5.4 Arithmetic and control unit

The arithmetic and control unit is composed of the following four blocks.

1 AD converter

The AES signal is input into the analog input terminals of the CPU (IC19) and converted to

digital.

2 SRAM with built-in battery (BC-RAM)

Consists of IC30, which stores exposure adjustment data to ensure that optimum exposure is

performed for each reproduction ratio and for automatic exposure.

3 Main CPU (IC19)

Incorporates software which computes the voltage to be applied to the lamp in accordance with

the copying mode, such as enlargement/reduction, automatic exposure, and manual exposure,

and the adjustment data in BC-RAM.

4 PWM timer circuit

Consists of the circuit shown in figure below.

The data resulting from the computation performed by the CPU described in item 3 above, are

converted to PWM signals by the gate array, and output to J2-A17 via IC10 from the PWM

output terminal of the gate array.

7.5.5 Lamp regulator circuit

The lamp regulator monitors the AC input voltage to control the exposure lamp to a fixed intensity.

(Method) • The AC input voltage is detected.

• The waveform rectifying circuit rectifies the AC input voltage to a DC voltage approxi-

mated to the effective value of the input voltage.

• This DC voltage and pulse signal are rectified, and compared with the reference voltage

and amplified.

• According to the output, the trigger pulse generation circuit generates a trigger pulse

synchronous with the power source frequency.

• The energization angle of the triac is controlled.

Makes the voltage at both ends of the lamp constant.

7.6 Automatic Original-Size Detection CircuitThis circuit detects the original size (standard sizes only) using the 3-beam type reflecting photosensor

and 2 – 3 reflecting photosensors (3 for A4 series, 2 for LT series) on the base frame of the optical unit.

7.6.1 Principle of original-size detection

On the base frame of the optical unit, the reflecting

photosensor (3-beam type) and 2 – 3 reflecting

photosensors (3 for A4 series, 2 for LT series). Each

photosensor consists of an infrared light emitting

diode (light-emitting side LED) and a phototransistor

(light-receiving side). When an original is placed

on the original glass, the light emitted by the LEDs

is reflected by the original and led to the

phototransistor. In this way, the presence or ab-

sence of an original is detected by whether reflected

light exists or not.

7.6.2 Original size detection

(1) If the copier is set in the original size detection mode, the carriage is set at its home position.

(2) Detection is performed in an instant when the original cover is opened, each sensor receive the

reflecting light and the condition of a matrix shown in (4) are satisfied.

(3) Original size detection is performed when the output signals from each sensor are input to the gate

array (IC18) and the main CPU (IC19). IC18 and IC19 are on the logic PC board.

8 PAPER FEEDING SECTION8.1 FunctionsThis unit sends paper which is set in the paper cassette or the bypass tray to the transfer position.

The paper feeding section is mainly comprised of manual feed roller, pick-up rollers, paper feed rollers,

separation rollers, transport rollers, aligning roller, manual feed switch, paper empty switch, paper size

switch, paper feed switch, paper stop switch and also their drive mechanism.

The following explains each part function.

(1) Pick-up roller/manual feed roller

Sends paper in the bypass tray or the paper cassette to the paper feed roller and the roller moves up

and down on each occasion of paper feeding.

(2) Paper feed roller

This is the opposite of the separation roller, sending paper fed from the pick-up roller to the transport

roller.

(3) Separation roller

This is the opposite of the paper feed roller. When two sheets or more are fed from the pick-up roller,

the load of the torque limiter of the separation roller is greater than the friction power between the

sheets of paper, the separation roller stops, causing the lower sheet also to stop and not be fed at

that moment. But in the case of single sheet feeding, it rotates at the same timing as the paper feed

roller so that it has the rotation force of that roller.

(4) Transport roller

Transport the paper from the feed roller to the aligning roller.

(5) Aligning roller

Paper fed from the paper feed roller is stuck against the aligning roller which is at rest, and leading

edge alignment is performed.

Then the aligning roller rotates to feed paper to the developing position.

Further, the aligning roller is contacted with the brush to prevent paper dust from adhering to the

aligning roller due to paper alignment. The following explains about switches which detect paper

size, paper presence and paper feeding position for ON/OFF control of each roller.

(6) Manual feed switch

Detects if paper is set in the bypass tray. If this is the case, manual paper feeding has priority over

cassette paper feeding.

(7) Paper-empty switch

This sensor detects paper in the paper cassette by the use of the actuator. When there is no paper in

the cassette, the actuator intercepts the transmitted light in the sensor, causing a paper-empty situ-

ation to be detected.

(8) Paper size switch

Consists of four push-type switches.

In the paper cassette, tabs are installed so that any of these switches (1 to 4) is pressed when a

paper cassette is installed in the copier.

Corresponding to which switch is being pressed, paper size detection is performed.

(9) Paper stop switch

Detects the leading/trailing edge of paper passing through the paper transport roller.

Jam detection such as for paper misfeeding, etc. is also used.

(10)Paper aligning switch

Detects that the leading edge of the paper has arrived at the aligning roller.

Also detects that the trailing edge of the paper has passed through the aligning roller.

If the former is detected, it reads that the aligning roller has completed paper alignment.

8.1.1 Manual pick-up roller vertical movement

When drive power is transmitted to the feed roller, rotation power is sent to the pick-up lever via the

spring clutch. Then the pick-up arm falls by its own weight and the spring clutch stops in the position in

which it has bumped into the stopper.

When the drive power of the feed roller is lost, the pick-up lever is lifted up by the force of the lever spring

after which the pick-up arm is also raised.

8.1.2 Cassette pick-up roller vertical movement

When the cassette is inserted, the cassette lever d pushes up the lever a in the direction A. Then the

pick-up roller is caused to fall by its own weight due to the link mechanism of the levers b and c.

8.1.3 Paper separation operation

Since no paper separation claws are used in the

cassette, a paper separation roller is installed in-

side the machine. The separation roller section

consists of a paper feed roller, separation roller,

spring joint, etc., as shown.

The feed roller is rotated by the feed clutch in the

direction of the arrow ( ) at the same timing

as the pick-up roller.

As shown in the lower right figure, two sheets feed-

ing are occured, since the friction between the

sheets is smaller, the lower sheet is stopped being

fed any further while the upper sheet is forced to

be transported by the feed roller in the direction of

the arrow ( ).

[Example]

When only one sheet of paper 1 has entered into

the separation roller section, since the feed roller’s

transporting force is stronger than the separation

roller’s braking force, the separation roller is forced

to rotate causing the sheet to be sent toward the

aligning roller ( ).

When, two sheets (1 and 2) have entered into

the separation roller section at the same time, since

the powers of the feed roller’s transporting and

separation roller’s braking are greater than the fric-

tion power of the paper, the paper 1 is transported

8.2 Cassette Feeding Operations8.2.1 Operation explanation

[A] From power-on until standby status

(1) When the power is turned on for the copier, the tray motors (M13/14) are set to ON and the trays at

each level start to rise. When the trays are raised, the tray-up switches (S28/29) are turned on (L →

H), and the tray motors (M13/14) are turned off, which stops the upward motion of the trays. At this

point, if the empty switches (S3/14) are off (L), it is determined that paper is not present. If the empty

switches are on (H), it is determined that paper is present. The trays stop in their raised position

regardless of whether there is paper or not.

(2) If the power is turned on when the cassette has been removed, the tray motor for that level does not

come on. When the cassette is inserted in the slot, the tray is raised and the presence or absence of

paper is determined.

(3) If either of the paper stop switches (S7/16) or the aligning switch (S8) is ON (because there is paper

in the paper path) when the power is turned on, it is determined that a paper jam has occurred and

operation is not possible until the paper is removed.

[B] Standby mode

(1) After the paper supply is checked by the raising of the trays as described above, the standby mode

is obtained. In the standby mode, the trays remain in their raised position.

(2) When the cassette is inserted or removed in the standby mode, the tray is raised again to check the

paper supply.

[C] Manual feeding

• The manual feed switch detects the presence of manual feeding paper.

• The manual solenoid is turned on, and the pick-up roller and the manual feed roller are rotated.

• The pick-up roller is lowered, and paper feeding is started.

• The leading edge of the paper turns on the paper aligning switch and is aligned at the aligning

roller.

• The manual feed clutch is turned off, and the pick-up roller and manual feed roller stopped rotat-

ing, and then the pick-up roller is raised.

• The aligning clutch is turned on, and the paper is transported to the transfer process.

[D] Cassette feeding (upper or lower)

• The feed clutch and the transport clutch are turned on, and the feed roller and the transport roller

are rotated, and then paper feeding is started.

• The leading edge of the paper turns on the paper stop switch, then the feed clutch is turned off.

• The leading edge of the paper turns on the aligning switch, and is aligned at the aligning roller.

• The transport clutch is turned off, and the transport roller is stopped.

• The aligning clutch is turned on, and the paper is transported to the transfer process.

9.5 Charging, Transfer, Separation, Developer-bias Control Circuit9.5.1 Outline

• Circuit to create the output control voltage Vc of the charging/transfer/separation/developer-bias.

• Vc is varied → output current or voltage varies linearly.

9.5.2 Operation explanation

• Charging/transfer/separation/developer-bias output adjustment value inside BC-RAM is output

to the main processor.

• Outputs control voltage data from the main processor to the D/A converter.

• Analog conversion by the D/A converter.

• Outputs control voltage Vc to the charging/transfer/separation/developer-bias transformer.

• Charging/transfer/separation/developer-bias transformer generates an output current or voltage

proportional to control the voltage Vc.

* Adjustment of control voltage Vc (adjustment data change) is performed in the AJ mode.

Notes: 1. Do not discharge developer material

from the toner replenishment orifice, as

the developer will adhere to the gear of

the toner cartridge drive motor, causing

the motor to seize.

2. Take care to avoid the connector becom-

ing smeared with developer material

when discharging is performed.

10.4 Brush Motor (Toner Motor (M15)) Drive CircuitThe toner motor is provided to supply toner for the developer unit.

The toner motor is driven by transistor 2SD1417 (Q3 on the logic PC board), and its circuit is structured

as follows.

The motor winding is connected to the +24V at its (+) side and to the collector of Q3 at its (–) side.

– When P62 (TMOT-ON signal) of the main-CPU becomes “L” level –

• Q8 is turned on → Q3 is turned on

• The +24V power supply supplies current in Q3 via the motor winding → the motor rotates

– When TMOT-ON signal becomes “H” level –

• Q8 is turned off → Q3 is turned off

• The current which was flowing in the motor winding flows via the route of diode D3.

~ It decreases at the rate of the time constant determined by the inductance and resistance of the

winding.

12.2 Description of Operations(1) Fuser unit

Heat and pressure are applied to the paper which has been separated from the drum and trans-

ported into the fuser unit and the toner image is fixed there. Steady pressure is applied always to the

upper and lower rollers by springs and they are rotated by the main motor. (The upper roller (heat

roller) has a heater lamp, but it does not rotate.)

The paper which has been fixed is smoothly removed from the heat roller by the use of the separation

claws.

The detection unit monitors the heat roller temperature using a thermistor, and when the temperature

becomes abnormally high, the power supply to the heater lamp is stopped by a thermostat.

(2) Paper-exit unit

The upper and lower exit rollers rotate using the gear drive from the fuser unit.

The paper which has completed the fixing process exits smoothly onto the receiving tray through the

upper and lower exit rollers.

12.3 Functions of Each Part(1) Heater lamp

This halogen lamp is located inside the heat roller, applying heat to the heat roller. The heater lamp is

secured as it is while the heat roller rotates.

(2) Heat roller

This roller is made of aluminum whose heat conductivity is relatively good, and has heat applied by

the heater lamp. Steady pressure is applied to both the heat and pressure rollers (mentioned later).

Fixing is performed by the transfer paper to be passed through between the two rollers as above so

that the toner image faces the heat roller. The toner is fused by the heat roller, the heat conductivity

rate is increased by the pressure roller, causing the toner to permeate the paper fiber. However,

during this process, a problem may occur. That is, because the toner is fixed by contacting with the

heat roller, the toner may adhere to the roller (called “offset phenomenon”). Therefore, for easier

removal of the toner from the heat roller, a Teflon coating has been applied on the surface of the heat

roller.

(3) Pressure roller

This is made of rubber for smooth application of pressure to the heat roller. The pressure roller has

pressure applied always by springs.

(4) Separation claws/Scraper

By the use of the separation claws/scraper, the paper which has been fixed to the both heat and

pressure rollers is smoothly removed.


SkipReturn

3560/70 S/M

(5) Cleaning felt roller

This cleans the toner remaining on the drum at fixing process. The cleaning felt roller is located so

that it can come in contact with the heat roller. The silicon oil soaked in the pressure roller is evapo-

rated by the heat roller, causing it to adhere to the surface of the heat roller. As a result, the cleaning

of the toner on the heat roller can be smoothly performed.

(6) Thermistor-1

Surface temperature of the heat roller should be maintained within a fixed range, (actually, around

200 °C), i.e. higher than the minimum temperature at which improper fixing may occur, lower than the

maximum temperature at which “baking” may occur. The thermistor detects the surface temperature

of the heat roller. If the temperature is lower than the standard temperature, it turns on the heater

lamp, if higher to turns it off.

(7) Thermistor-2

Temperature distribution in axis of the heat roller may differ greatly on its center and ends by condi-

tions. The thermistor-2 detects temperature of the heat roller end.

When either thermistor-1 or -2 detects the temperature over the specifieds, heater lamp is turned off

by their thermal controls.

(8) Thermostat

When the surface temperature of the heat roller becomes excessively high due to thermistor failure,

etc., the thermostat stops the power supply to the heater lamp.

As the thermostat used in this copier is a type which protects against abnormal operation, when it

detects an abnormal operation, it is set to stay OFF. Therefore, during repair, this should be replaced

together with other damaged parts in the fuser unit.

(9) Exit rollers

Through the exit rollers, the paper removed by the separation claws or scraper exits smoothly onto

the receiving tray via the ADU exit roller.

3560/70 S/M

12.4 Heater Control Circuit12.4.1 Temperature detection unit

To maintain the heat roller temperature, this unit detects the heat-roller temperature by thermistor-1, and

then performs heater lamp ON/OFF control.

The thermistor is an electrical element whose resistance decreases as its detected temperature in-

creases. If the thermistor is open-circuited, the control circuit erroneously determines that the fuser tem-

perature is extremely low and continues to energize the heater lamp. As a result, the fuser temperature

rises abnormally high, possibly activating the thermostat provided for safety purposes. The CPU works to

detect the breakage of the thermistor and prevents the condition mentioned above.

The following abnormalities are detected:

(1) Abnormal detection during warming up

Maximum 25 sec. after the power has been turned on, if the thermistor-1 output voltage does not

exceed 0.078 V, CALL SERVICE (C41) is displayed.

(2) Abnormal detection during stand-by/copying (Thermistor-1)

If the thermistor-1 output voltage decreases to and remains at 0.078 V or lower for 260 msec. or

more, CALL SERVICE (C43) is displayed.

(3) Abnormal detection during stand-by/copying (Thermistor-2)

If the thermistor-2 output voltage decreases to and remains at 0.192 V or lower for 260 msec. or

more, CALL SERVICE (C45) is displayed.

(4) C40 error counter control

• For improved fuser-unit safety, the CPU works as follows: After the C41 error occurs two times in

succession, even when the power is turned on, the heater will not come on and the C41 error will be

immediately displayed.

• However, with “1” or less stored in the C40 counter, if the copier becomes ready correctly, the C40

counter clears to “0”.

• After CALL SERVICE (C41 – C45) has occurred and the thermistor, heater lamp, etc. have been

repaired (or replaced), if turning on the power switch does not cause the heater to energize resulting

in a C40 error, check the C40 counter (08-code 89) and reset it to “0”.


SkipReturn

3560/70 S/M

Surface temperature of heat roller: 200°C (Thermistor resistance value: about 3.2 kΩ)

Reference

1. A value other than 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9 is never written in the C40 counter.

• At the power on, if the heater does not turn on and the copier goes into the C40 CALL SERVICE,check the C40 counter if it is 2 or more. If it is 2 or more, be sure to check the thermistor and heaterlamp, and after repair, reset the C40 counter (08-code 89) to 0 and then turn on the power switch.

• If the value of the C40 counter is more than 10 (11, for example), it may be possible that BC-RAM orthe data in it have been destroyed by charger leaking, etc. In this case, check the guide bias, high-voltage transformers, charger wires, etc. for any defects. Also, all the data inside BC-RAM need to be

rechecked.2. Relationship between the output voltage and the fusing temperature.

• 200°C corresponds to approx. 2.5V and 0.078 V corresponds to approx. 40°C.

3. Relationship between heat roller surface temperature and thermistor-1 resistance.

4. Temperature control at heat roller endsDuring multicopying, the temperature at each end (no paper-contact area) of the heat roller normally tends

to rise higher that the controlled temperature of the paper-contact area. Therefore, the circuit is so devisedthat if the temperature in the no paper-contact area rises to 245°C, the second thermistor detects this,causing the heater to be turned off immediately regardless of the temperature in the paper-contact area.

12.4.3 Control for abnormal heater condition

When something abnormal occurs in the heater turn-on circuit, such as a shorted triac, it may become

incapable of ON/OFF control. In this case, the microcomputer detects abnormal temperatures through

the first and second thermistors, determines the corresponding error codes and counter values, and

causes the main power to switch off to protect the fuser unit.

(1) Temperature detection

The following abnormal temperatures are detected by the respective thermistors:

First thermistor: 230°C

Second thermistor: 270°C

(2) Error codes

“C44”: Displayed when keys C/S + 8 are pressed simultaneously at the time of Call

Service.

Counter value “9”: Displayed when you input “89” in the AD (0 + 8) mode.

(3) Machine condition

After deenergizing all outputs (heater lamp, exposure lamp, control-panel displays, motors, etc.), the

microcomputer causes the main power to switch off.

(4) Corrective action

After the error code and counter value in (2) have been determined, abnormal temperature detection

in (1) continues. So, if the main switch is turned on immediately, it will be turned off again as long as

the temperature on the heater surface remains above the abnormal detection temperatures of

thermistors. Thereafter, this will be repeated. So, after waiting for the heater surface temperature to

drop, turn on the main switch and you can check the counter value before the main switch is turned

off again. After confirming that an abnormal heater condition has occurred, repair the problem and

then clear code 89 of the AD (0 + 8) mode with “0”. After that, you can bring the copier into its

normal operating condition.

13.3 Description of ADU Operation13.3.1 Paper stacking operation

When the ADU (duplex copying) mode is selected and the PRINT key is pressed on the copier’s control

panel, the ADU motor starts rotating, and the side guides and the end guide in the stacking section are

moved to the positions corresponding to the selected size of paper by their respective motors. Then, the

stack clutch comes on, the transport roller rotates and the EXIT/ADU selection gate is switched in the

direction of the stacking section by the gate solenoid.

The copy paper which has exited from the copier is sent into the ADU’s open guide by the EXIT/ADU

selection gate. This paper is further carried by transport rollers into the stacking section, where the paper

is stacked face up. This operation is repeated until the specified number of sheets are stacked.

At the start of the stacking operation, the side guides are set with a 5 mm gap relative to each side of the

paper, and each time 5 sheets are stacked consecutively during stacking, the side guides perform a

paper aligning operation.

A jam switch is provided to have paper jams in the open guide detected. The empty switch is to detect

whether or not paper is present in the stacking section.

13.3.2 Duplex copying

After the paper stacking operation, when a second original is set and the PRINT key is pressed, the ADU

motor starts rotating, causing the elevator arm to rotate. This will cause the tray positioned under the

stacked sheets of paper to rise, making the sheets come into contact with the rotating pick-up roller and

sending the topmost sheet out. The separation roller rotates with the feed roller. At this time, if two or

more sheets are sent out, the separation roller stops rotating, causing the lower sheet(s) to stop its

movement.

The sheet of paper thus sent out is carried by the copier’s upper transport roller to the copier’s aligning

roller and aligned. The sheet is then copied on the side not copied previously. The sheet copied on both

its sides passes through the copier’s exit roller and over the EXIT/ADU selection gate which is already

positioned in the direction of existing, further passing through the exit roller to exit finally into the receiv-

ing tray.

• When the ADU motor rotates (arrow A) and the feed clutch (Z28) energizes, the pick-up roller and

the ADU stack/feed roller are rotated in the feeding direction (arrow C).

At this time, the transport rollers do not rotate since a one-way clutch is contained inside of the gear

(Z16) on the transport roller shaft.

13.8 Description of Operation13.8.1 General operation

(1) Initializing

When the power switch is turned on or when the front cover is opened/closed or when the ADU is

pulled out/pushed in, this operation is performed.

(2) Stacking operation

This is an operation in which sheets of paper fed from the cassette and copied on their surface (first

side) are sent into the ADU stack section and stacked there.

(3) Duplex copying

Sheets of paper which have been copied on their first sides are automatically sent into the copier and

copied on their reverse surface (second side).

(4) ADU paper feeding

This operation causes sheets of paper to be fed from the ADU into the copier.

13.8.2 Description of each operation

[A] Initializing

[A-1] Initializing when the power switch is turned on

(1) When the power switch is turned on, the end motor (END-MOT) DM2 rotates to move the end

guide in the stack section to its home position.

(2) The side motor (SID-MOT) DM3 rotates to move the side guides to their home position.

[A-2] Initializing when the copier’s front cover is opened/closed

(1) The operation in step (1) above is performed.

[A-3] Initializing when the ADU is pulled out/pushed in

(1) The end motor (END-MOT) DM2 rotates to move the end guide to its home position once,

then moves it to the position corresponding to the selected size of paper.

(2) The side motor (SID-MOT) DM3 rotates to move the side guides to their home position once,

then moves them to the position corresponding to the selected size of paper.

[B] Stacking operation

(1) When the PRINT key is pressed, the SID-MOT DM3 and END-MOT DM2 are rotated to

move the side and end guides to the position corresponding to the specified size of paper, and

the ADU-MOT DM1 is rotated clockwise to transport the paper. STSOL ( ) is en-

ergized to position the EXIT/ADU selection gate in the direction of stacking, and STCLT CLT2

is energized to rotate the ADU transport rollers in the direction of stacking.

(2) Jam detection inside the ADU is performed as follows:

JAM-SW SA4 is checked if it is turned on within a specified period of time after the copied

paper turned on the copier’s exit switch. The switch is also checked if it is turned off within a

specified period of time after the exit switch was turned off by the paper.

SOL 1

2060, 2860/70 ADU 13 - 28 Dec. 1996 © TOSHIBA

SOL 1

SOL 1

SOL 1

(3) Each time five sheets of paper are stacked in the ADU, the side motor (SID-MOT) DM3 is

rotated to move the side guides so that the sheets stacked are aligned, then the side guides are

returned to their previous position.

(4) The above procedure (2)~(3) is repeated until the specified number of copies are made.

(5) After the final sheet is stacked in the ADU stack section, STSOL ( ), STCLT

CLT2 and ADU-MOT DM1 are turned off.

[C] Feeding from ADU

(1) When the PRINT key is pressed, the SID-MOT DM3 is rotated to move the side guides to

the specified size of paper and ADU-MOT DM1 is rotated clockwise and FEDCLT CLT1 is

turned on, causing the ADU feed roller and pick-up roller to rotate.

(2) Due to the operation in (1), the ADU tray is raised, causing the copy paper to come into contact

with the pick-up roller for paper feeding.

(3) A sheet of paper is fed out of the ADU and transported toward the copier’s aligning roller.

(4) When the sheet pushes the copier’s paper transport switch on, FEDCLT CLT1 is turned off,

causing the pick-up roller and feed roller to stop rotating.

(5) Then, the copier’s aligning roller starts rotating, and the copying process commences.

(6) The above procedure (2)~(5) is repeated until the specified number of copies are made. When

copies are finished, ADU-MOT DM1 is stopped rotation.

[D] Duplex copying

(1) When the first-side copying operation is started, ADU-MOT DM1 is rotated, and the side and

end guides are moved to the position of specified paper size by the SID-MOT DM3 and END-

MOT DM2 .

Additionally, the STSOL ( ) and the STCLT CLT2 are turned on in the same way as

the [B] Stacking operation.

(2) The first-side copied sheet is transported into the ADU from the copier exit switch and gate

sections, and then stacked through the JAM-SW SA4 .

The ADU inside jam symbol comes on when the JAM-SW SA4 is not turned on within a

specified time after the copier exit switch is turned on, or the JAM-SW is not turned off within a

specified time after the copier exit switch is turned off.

(3) Each time five sheets of paper are stacked, the stacked sheets are aligned by the side motor

SID-MOT DM3 moving the side guides.

(4) The above procedure (2)~(3) is repeated until the specified number of sheets are stacked.

(5) The final sheet is stacked in the ADU, and then STSOL ( ) and STCLT CLT2 are

turned off.

(6) When the RADF is not used, ADU-MOT DM1 is stopped once to turn over the original. After

turning over the original, ADU-MOT DM1 is rotated again to make a copy of the next original

in step 7 or later.

When the RADF is used, ADU-MOT DM1 is not stopped since the original is turned over

continuously.

Dec. 1996 © TOSHIBA 13 - 29 2060, 2860/70 ADU

(7) When the second-side copying is started, the side guides are moved by the SID-MOT DM3 to

the specified size position.

(8) When the FEDCLT CLT1 is turned on, the ADU paper feed tray is lifted up, and also the pickup

and feed rollers are driven, then one sheet of paper is separated and fed.

When the sheet reaches the copier’s transport switch, the FEDCLT CLT1 is turned off.

The ADU feed jam symbol comes on when the copier’s transport switch is not turned on within a

specified time after the FEDCLT CLT1 is turned on.

(9) The above step (8) is repeated until the specified number of copies are made. After copying has

been finished, ADU-MOT DM1 is stopped.

13.8.4 Detection of abnormal status

When an abnormal condition is detected inside the ADU, a symbol corresponding to the condition is

shown on the copier’s control panel. The following kinds of abnormal status may be encountered:

(1) Abnormal statuses which can be cleared without pulling out/pushing in the ADU:

• Paper misfeeding which occurs while paper is being fed from the stack section.

(2) Abnormal statuses which can be cleared by pulling out/pushing in the ADU:

• Paper misfeeding in the paper stack section.

(3) Abnormal statuses which can be cleared only by turning off/on the copier’s power switch:

• When the side guides or end guide cannot be initialized to their correct positions.

[A] Paper misfeeding

(1)Paper misfeeding during duplex copying:

While paper is fed from the ADU, if the copier’s P-STP-SW is not turned on within about 1 sec.

after FEDCLT CLT1 was energized, it is judged that paper misfeeding has occurred during

ADU paper feeding, and a paper misfeed symbol is displayed. This condition can be cleared by

opening/closing the copier’s side cover.

(2)Paper misfeeding during paper stacking:

During paper stacking, if the ADU’s JAM-SW SA4 is not turned on within about 3 sec. after the

copier’s EXIT-SW was turned on/off, it is judged that paper misfeeding has occurred inside the

ADU. To clear this condition, pull out the ADU, remove the misfed sheet, then push in the ADU. (If

necessary, open/close the copier’s front cover.)

[B] Abnormal statuses at power on

(1)Paper remaining in the stack section at power on:

If a sheet of paper is left in the stack section when the power is turned on, a symbol indicating that

paper is still there is displayed on the copier’s control panel when the duplexing mode is selected.

This mode cannot be started until the paper is removed.

(2)Misfed paper remaining inside the ADU when the power is turned on:

If a misfed sheet of paper remains on the ADU’s paper path when the power is turned on, the ADU

misfeed symbol is shown. To clear this condition, pull out the ADU, remove the misfed sheet and

then push in the ADU. (If necessary, open/close the copier’s front cover.)

[C] “Serviceman Call” errors

(1)The paper side guides and end guide cannot be initialized :

During the initialization of the SID-MOT DM3 and END-MOT DM2 , if the respective home

switch positions are not detected, a message will be displayed indicating that the ADU cannot

function.

14.3 Power Supply Circuit (PS-ACC)[A] 115 V



HINT

[B] 200 V



HINT

[C] 200 V (French production)

Dec. 1996 © TOSHIBA 15 - 1 2060, 2860/70 POWER

15. POWER STABILIZING CIRCUIT15.1 Power CircuitThis power circuit has the following 3 DC outputs.

DC output Rating Main load

5V 5.1V±5% LED eraser array, LCD, LED, logic IC power supplies

24VA – E, I, J 24V±10% Motors, clutches, high-voltage transformer, scanning motor

24VF – H 24V±10% RADF, optional sorter, main switch

15.2 Description of OperationWhen the main switch on the copier is turned ON, AC power is supplied to the switching power supply,

and then the 5V power supply for the logic ICs, and the 24VF – H DC power supply for the RADF and

sorter are turned ON. At this time, if the door switch is ON (closed), the 24VA – E, I, J DC voltages are

turned ON.

Each of these power circuit is provided with overcurrent protection fuses (excluding 5V) and an overcurrent

protection unit is provided in the circuit to protect the copier’s power circuit in case of an overload or a

power output short.

When these functions are in operation, remove the cause of the overload or short. When a fuse has

blown, replace the fuse. Or, when overcurrent protection in the circuit is in operation, turn the main switch

OFF then ON again to enable circuit operation.

The power circuit is also provided with an overvoltage protection function. This function prevents the

power supply from turning ON to protect electrical components if two different voltages short. If this

happens, remove the cause of the short, and turn the main switch OFF then ON again to enable circuit

operation.
