IMPORTANT WARNING ITEMS

[1] UNAUTHORIZED MODIFICATIONSKonica copiers have gained a reputation for being reliable

products. This has been attained by a combination of outstand-ing design and a knowledgeable service force.

The design of the copier is extremely important. It is the design

process that determines tolerances and safety margins for

mechanical, electrical, and electronic aspects. It is not reason-

able to expect individuals not involved in product engineering

to know what effect may be caused by altering any aspect of the

machines design. Such changes have the potential of degrad-

ing product performance and reducing safety margins.

For these reasons, installation of any modification not specifi-

cally authorized by Konica Corporation, is strictly prohibited.

The following list of prohibited actions is not all-inclusive, but

demonstrates the intent of this policy.

CAUTION:

(1) Using an extension cord or any unauthorized power

cord adapter.

(2) Using any fuse that is not of a type specified by

Konica.

(3) Using wire, paper clips, solder, etc., to replace or

eliminate any fuse (including temperature fuses).

(4) Removing (except for replacement) any air filter.

(5) Defeating the operation of relays by any means (such

as wedging paper between contacts).

(6) Causing the machine to operate in a fashion other

than as it was designed.

(7) Making any change which might have a chance of

defeating built-in safety features.

(8) Using any unspecified replacement parts.

[2] GENERAL SAFETY GUIDELINESThis copier has been examined in accordance with the laws

pertaining to various product safety regulations prior to leavingthe manufacturing facility to protect the operators and service

personnel from injury. However, as with any operating devise,

components will break down through the wear-and-tear of

everyday use, as will additional safety discrepancies be dis-

covered.

For this reason, it is important that the technician periodically

performs safety checks on the copier to maintain optimum

reliability and safety.

CAUTION:

(1) Avoid injury.

(2) Ensure that the copier is disconnected from its powersource before continuing.

(3) Do a job wearing clothes which make the job easy and

safe.

In case that even touching driving section, there must

be no posibility of any injury like rolling up clothes.

The following checks, not all-inclusive, should be made during

each service call:

CAUTION:

(1) Look for sharp edges, burrs, and damage on all exter-

nal covers and copier frame.

(2) Inspect all cover hinges for wear (loose or broken).

(3) Inspect cables for wear, frays, or pinched areas.

(4) Ensure that the power cord insulation is not damaged

(No exposed electrical conductors).

(5) Ensure that the power cord is properly mounted to the

frame by cord clamps.

WARNING:

(1) Check the continuity from the round lug (GND) of the

power cord to the frame of the copier. Ensure continu-

ity.

An improperly grounded machine can cause an elec-

trically-charged machine frame.

(2) When an earth cable is connected to the improperposition, there is a possibility of danger such as

explosion or an electric shock. Therefore, the earth

cable should not be connected to the following items.

a. Gas pipe

b. Lightning rod

c. Earth cable for telephone line

d. Water service pipe made of resin, and water service

pipe and faucet which are not approved to be

grounded by the Waterworks Bureau.

[3] SAFEGUARDS DURING SERVICE CALLS

CAUTION:

(1) Confirm that all screws, parts, wiring and connector

which are removed during maintenance are installed

in their original positions.

(Especially, negligence of inserting a connector, a

sandwiched cord and negligence of driving a screw

should be avoided.)

(2) When disconnecting connectors, do not pull the wir-

ing, particularly on AC line wiring and high voltage

parts.

(3) Do not route the power cord where it is likely to be

stepped on or crushed.

(4) Carefully remove all toner and dirt adhering to anyelectrical units or electrodes.

(5) After part replacement or repair work, route the wiring

in such a way that it does not contact any burrs or

sharp edges.

(6) Do not make any adjustments outside of the specified

range.

[4] WHEN USING SERVICE MATERIALS

CAUTION: Care should be exercised when using

isopropyl alcohol due to its flammability.

When using alcohol to clean parts, ob-serve the following precautions.

(1) Remove power from the equipment.

(2) Use alcohol in small quantities to avoid spillage or

pudding. Any spillage should be cleaned up with rags

and disposed of properly.

(3) Be sure that there is adequate ventilation.

(4) Allow a surface which has been in contact with alcohol

to dry for a few minutes to ensure that the alcohol has

evaporated completely before applying power or in-

stalling covers.

CAUTION: Though toner and developer are harm-

less, pay attention not to inhale them, or

not to expose eyes to them excessively. If

this happens, wash eyes well with clear

water and consult a doctor.

[5] ACTION TO TAKE IN THE EVENT OF A

SERIOUS ACCIDENT(1) If an accident occurs, the sales company or dealer that

was notified of the accident first must take necessary

emergency action to assist any injured persons and also

prevent any further damage or injury.

(2) If the customer notifies you of a serious accident, promptly

check the situation regarding damage, injury, and so on,

and report to Sales Company. Upon receiving this report,

Sales Company must report to Konica Corporation.

(3) In order to determine the cause of the accident, preserve

the site of the accident and also the machine itself, witness

the investigation, and also follow any instructions from

Sales Company or Konica Corporation.

[6] SUMMARYIt is the responsibility of every technician to use professional

skills when servicing Konica products. There are no short cuts

to high-quality service. Each copier must be thoroughly in-

spected with respect to safety considerations as part of every

routine service call. The operability of the copier, and more

importantly, the safety of those who operate or service the

copier, are directly dependent upon the conscientious effort of

each and every technician.

Remember .... when performing service calls, use good judge-

ment (have a watchful eye) to identify safety hazards orpotential safety hazards that may be present, and correct these

problem areas as they are identified-the safety of those who

operate the copier as well as those who service the copier

depend on it!

[3] L2, L3, L4 (fixing heater lamp) overheating protection

circuit

These safety circuits are described below to provide the

service enginear with a renewed awareness of them in order to

prevent servicing errors that may impair their function.

[1] Overall Safety Circuit Protector

1. Protection function provided by software

When the L1 CONT signal output from the protection

function CB (control board) by software becomes [L], L1

lights. At the same time, the L1 FB signal, which indicates

that L1 is lit, is output from CVR to the CB.

The CB monitors both the L1 CONT and L1 FB signals.

If they differ from each other, RL1 (main relay) will be

turned OFF, and power to L1 will be cut off.

CAUTION: The function of RL1 must not be de-

activated under any circumstances.

2. Protection function using H.T. (hardware timercircuit)If L1 remains lit for moer than prescribed time because of

some abnormality, the hardware timer on CVR will operate,

forcibly cutting off the relay on this board.

CAUTION: The function of relay must not be de-


3. Protection function using f1 (optics temperaturefuse)

If the temperature in the vicinity of f1 rises above

prescribed temperature f1 will blow, cutting off the flow

of current to L1.

CAUTION: Do not under any circumstances use a

piece of wire, etc., In place of f1.
