3.3 Concept of parts life

*1: A waste toner full condition is detected with detecting the actual waste toner emissions.*2: Once the toner-full is detected, it has to be replaced with the new waste toner bottle in

order to reset.*3: The count condition is different according to the media length of the sub scanning direc-

tion.

Description Near life value Life value /

Max. number of printed pages

Waste toner bottle

A waste toner full condition is detected when about 2,500 printed pages have been produced after a waste toner near full condition has been detected.When the maximum number of printed pages is reached, the print is inhibited.

⎯ 18,000 *1, 2

DescriptionLife value

(Specification value)

Max. number of printed pages

Fusing unit

The number of prints made is counted. *3The number of prints made is compared with the value of the number of hours through which the fus-ing drive motor has turned translated to a corre-sponding value of the number of prints made and the value, whichever reaches the life specification value, is detected.When the maximum number of printed pages is reached, the print is inhibited.

120,000 150,000

Transfer beltIt is detected by counting the number of hours the transfer belt turns. The printing is prohibited when it reaches to the maximum printed pages.

120,000 150,000

Imaging unit C/M/Y

The hours which the PC drum has turned is com-pared with the value of the number of hours through which the imaging roller has turned translated to a corresponding value of hours and the value, which-ever reaches the life specification value, is detected.* The hours which the PC drum has turned is the

value of the number of distance through which the PC drum has run translated to a corresponding value of the number of hours and the value.

6.1 Disassembly/adjustment prohibited items

A. Paint-locked screws

NOTE• To prevent loose screws, a screw lock in blue or green series color is applied to

the screws.• The screw lock is applied to the screws that may get loose due to the vibrations

and loads created by the use of machine or due to the vibrations created during transportation.

• If the screw lock coated screws are loosened or removed, be sure to apply a screw lock after the screws are tightened.

B. Red-painted screws

NOTE• The screws which are difficult to be adjusted in the field are painted in red in order

to prevent them from being removed by mistake.• Do not remove or loosen any of the red-painted screws in the field. It should also

be noted that, when two or more screws are used for a single part, only one repre-sentative screw may be marked with the red paint.

C. Variable resistors on board

NOTE• Do not turn the variable resistors on boards for which no adjusting instructions

are given in Adjustment/Setting.

D. Removal of PWBs

CAUTION• When removing a circuit board or other electrical component, refer to “Handling of

PWBs” and follow the corresponding removal procedures.• The removal procedures given in the following omit the removal of connectors and

screws securing the circuit board support or circuit board.• Where it is absolutely necessary to touch the ICs and other electrical components

on the board, be sure to ground your body.

Adjustment/Setting7. How to Use the adjustment section• This section contains detailed information on the adjustment items and procedures for

this machine.• Throughout this section the default settings are indicated by “ ”.

Advance checksBefore attempting to solve the customer’s problem, the following advance checks must be made:

• Does the power supply voltage meet the specifications?• Is the power supply is properly grounded?• Does the machine share a power supply with any other machine that draws a large cur-

rent intermittently (for example, an elevator or air conditioner that generates electrical noise)?

• Is the installation site level and environmentally appropriate (for example, away from high temperatures, high humidity, direct sunlight, direct ventilation, etc.?

• Does the original have a problem that may cause a defective image?• Is the density properly selected?• Is the correct media being used for printing?• Are the units, parts, and supplies used for printing (developer, PC drum, etc.) properly

replenished and replaced when they reach the end of their useful service life?• Is there an adequate supply of toner in the toner cartridges?

CAUTION• Unplug the machine’s power cord before starting a service job procedure.• Use special care when handling the fusing unit, which can be extremely hot.• The developing unit has a strong magnetic field. Keep watches and measuring

instruments away from it.• Take care not to damage the PC drum with a tool or similar device.• Do not touch IC pins with your bare hands.

<How to read sensor information>• Convert the numerical value of the hexadecimal number printed on [ELEMENT DATA]

into the binary number, it compares with the allocation of each BIT, and the status of the sensor is confirmed.

ex. When sensor information1 is displayed as 0x0005. 1. Convert four end digits “0005” of 0x0005 into the binary number (14 digits).2. The BIT number is allocated in converted value “00000000000101.”

(BIT0 to BIT13 is sequentially allocated from the first digit.)

3. In this case, because BIT No. “0” and “2” become “1”, so it can be confirmed that the tray 2 device detection sensor is “In position” state and the tray 2 paper near-empty sensor is “Blocked” states from the sensor information table.

(SENSOR INFORMATION 1)

Conversion method from hexadecimal number to binary number1. The hexadecimal number (four digits) is converted in each digit based on the following

table.

2. Match the converted numerical value of four digits, then two head digits are excluded and it is assumed the binary number of 14 digits.

• If either value is out of the specifica-tion, follow the procedures shown below to adjust it to satisfy the specifi-cation.

• If the value of all color, C,M,Y,K, satisfy the specification, proceed to step 11.

7. Open the front door.8. Turn the dkew adjustment dial of the

corresponding PH with flathead screwdriver.

• To the left: When the step value goes - direction

• To the right: When the step value goes + direction

<Adjustment sample>If the yellow value, among the step values confirmed in step 6, is [-5], which means out of the specification, turn the skew adjustment dial of PH (Yellow) to the left (- direction) for 5 clicks.

9. Close the front door and select [SERVICE MENU] → [DIAGNOSIS MENU] → [FUNC-TION MENU] → [PH SKEW ADJ] → [ADJUSTMENT PRINT] and output the test pat-tern.

10. After ADJUSTMENT PRINT is completed, display [SERVICE MENU]] → [DIAGNOSIS MENU] → [FUNCTION MENU] → [PH SKEW ADJ] → [PH REGIST VALUE] again and check if the regist value of each color C,M,Y, is within the specification.

NOTE• Each color’s regist value displayed on [PH REGIST VALUE] changes every time the

image stabilization is conducted. Therefore the value may change even if skew adjustment is not made.

• If either value is out of the specification, repeat step 7 to 10 to continue the adjustment until all CMYK colors satisfy the specification.

11. Finish the adjustment.

3.1 Disassembly/adjustment prohibited items

A. Paint-locked screws

NOTE• To prevent loose screws, a screw lock in blue or green series color is applied to

the screws.• The screw lock is applied to the screws that may get loose due to the vibrations

and loads created by the use of machine or due to the vibrations created during transportation.

• If the screw lock coated screws are loosened or removed, be sure to apply a screw lock after the screws are tightened.

B. Red-painted screws

NOTE• The screws which are difficult to be adjusted in the field are painted in red in order

to prevent them from being removed by mistake.• Do not remove or loosen any of the red-painted screws in the field. It should also

be noted that, when two or more screws are used for a single part, only one repre-sentative screw may be marked with the red paint.

C. Variable resistors on board

NOTE• Do not turn the variable resistors on boards for which no adjusting instructions

are given in Adjustment/Setting.

D. Removal of PWBs

CAUTION• When removing a circuit board or other electrical component, refer to “Handling of

PWBs” and follow the corresponding removal procedures.• The removal procedures given in the following omit the removal of connectors and

screws securing the circuit board support or circuit board.• Where it is absolutely necessary to touch the ICs and other electrical components

on the board, be sure to ground your body.

Adjustment/Setting4. How to use the adjustment section• “Adjustment/Setting” contains detailed information on the adjustment items and proce-

dures for this machine.• Throughout this “Adjustment/Setting,” the default settings are indicated by “ ”.

Advance checksBefore attempting to solve the customer problem, the following advance checks must be made.Check to see if:

• The power supply voltage meets the specifications.• The power supply is properly grounded.• The machine shares the power supply with any other machine that draws large current

intermittently (e.g., elevator and air conditioner that generate electric noise).• The installation site is environmentally appropriate: high temperature, high humidity,

direct sunlight, ventilation, etc.; levelness of the installation site.• The density is properly selected.• Correct paper is being used for printing.• The units, parts, and supplies used for printing (developer, PC drum, etc.) are properly

replenished and replaced when they reach the end of their useful service life.• Toner is not running out.

Caution• Be sure to unplug the power cord of the machine before starting the service job

procedures.• If it is unavoidably necessary to service the machine with its power turned ON, use

utmost care not to be caught in the scanner cables or gears of the exposure unit.• Special care should be used when handling the fusing unit which can be

extremely hot.• The developing unit has a strong magnetic field. Keep watches and measuring

instruments away from it.• Take care not to damage the PC drum with a tool or similar device.• Do not touch IC pins with bare hands.

Maintenance2. Other

2.1 Disassembly/adjustment prohibited items

A. Paint-locked screws

NOTE• To prevent loose screws, a screw lock in blue or green series color is applied to

the screws.• The screw lock is applied to the screws that may get loose due to the vibrations

and loads created by the use of machine or due to the vibrations created during transportation.

• If the screw lock coated screws are loosened or removed, be sure to apply a screw lock after the screws are tightened.

B. Red-painted screws

NOTE• The screws which are difficult to be adjusted in the field are painted in red in order

to prevent them from being removed by mistake.• Do not remove or loosen any of the red-painted screws in the field. It should also

be noted that, when two or more screws are used for a single part, only one repre-sentative screw may be marked with the red paint.

C. Variable resistors on board

NOTE• Do not turn the variable resistors on boards for which no adjusting instructions

are given in Adjustment/Setting.

D. Removal of PWBs

CAUTION• When removing a circuit board or other electrical component, refer to “Handling of

PWBs” and follow the corresponding removal procedures.• The removal procedures given in the following omit the removal of connectors and

screws securing the circuit board support or circuit board.• Where it is absolutely necessary to touch the ICs and other electrical components

on the board, be sure to ground your body.

Adjustment/Setting3. How to use the adjustment section• “Adjustment/Setting” contains detailed information on the adjustment items and proce-

dures for this machine.• Throughout this “Adjustment/Setting,” the default settings are indicated by “ ”.

Advance ChecksBefore attempting to solve the customer problem, the following advance checks must be made.Check to see if:

• The power supply voltage meets the specifications.• The power supply is properly grounded.• The machine shares the power supply with any other machine that draws large current

intermittently (e.g., elevator and air conditioner that generate electric noise).• The installation site is environmentally appropriate: high temperature, high humidity,

direct sunlight, ventilation, etc.; levelness of the installation site.• The original has a problem that may cause a defective image.• The density is properly selected.• Correct paper is being used for printing.• The units, parts, and supplies used for printing (developer, PC drum, etc.) are properly

replenished and replaced when they reach the end of their useful service life.• Toner is not running out.

Caution• Be sure to unplug the power cord of the machine before starting the service job

procedures.• If it is unavoidably necessary to service the machine with its power turned ON, use

utmost care not to be caught in the scanner cables or gears of the exposure unit.• Special care should be used when handling the fusing unit which can be

extremely hot.• The developing unit has a strong magnetic field. Keep watches and measuring

instruments away from it.• Take care not to damage the PC drum with a tool or similar device.• Do not touch IC pins with bare hands.
