specified ones for maintaining the safety and performance of the set.

SHARP CORPORATION

This document has been published to be used

for after sales service only.

The contents are subject to change without notice.

CAUTION

This product is a class 1 laser product that complies with 21CFR 1040.10 and 1040.11 of the CDRH standard and IEC825. This means that this

machine does not produce hazardous laser radiation. The use of controls, adjustments or performance of procedures other than those specified

herein may result in hazardous radiation exposure.

This laser radiation is not a danger to the skin, but when an exact focusing of the laser beam is achieved on the eye’s retina, there is the danger of spot

damage to the retina.

The following cautions must be observed to avoid exposure of the laser beam to your eyes at the time of servicing.

1) When a problem in the laser optical unit has occurred, the whole optical unit must be exchanged as a unit, not as individual parts.

2) Do not look into the machine with the main switch turned on after removing the developer unit, toner cartridge, and drum cartridge.

3) Do not look into the laser beam exposure slit of the laser optical unit with the connector connected when removing and installing the optical

system.

4) The middle frame contains the safety interlock switch.

Do not defeat the safety interlock by inserting wedges or other items into the switch slot.

Warning!

This product is a class A product.

If it is operated in households, offices or similar surroundings, it can produce radio interferences at other

appliances, so that the user has to take adequate countermeasures.

[1] NOTE FOR SERVICING

6) Do not leave the machine with the cabinet disassembled.

Do not allow any person other than a serviceman to touch inside

the machine. It may cause an electric shock, a burn, or an injury.

7) When servicing, do not breathe toner, developer, and ink exces-

sively. Do not get them in the eyes.

If toner, developer, or ink enters you eyes, wash it away with water

immediately, and consult a doctor if necessary.

8) The machine has got sharp edges inside. Be careful not to dam-

age fingers when servicing.

9) Do not throw toner or a toner cartridge in a fire. Otherwise, toner

may pop and burn you.

10) When replacing the lithium battery of the PWB, use a specified one

only.

If a battery of different specification is used, it may be broken,

causing breakdown or malfunction of the machine.

11) When carrying a unit with PWB or electronic parts installed to it, be

sure to put it in an anti-static-electricity bag.

It may cause a breakdown or malfunctions.

This Service Manual uses some photographs to assure safe operation.

Please understand the meanings of photographs before servicing.

WARNING: If this WARNING should be ignored, a serious danger

to life or a serious injury would be resulted.

CAUTION: If this CAUTION should be ignored, an injury or a

damage to properties would be resulted.

1. Warning for servicing

1) Be sure to connect the power cord only to a power outlet that

meets the specified voltage and current requirements.

Avoid complex wiring, which may lead to a fire or an electric shock.

It may cause a fire or an electric shock.

2) If there is any abnormality such as a smoke or an abnormal smell,

interrupt the job and disconnect the power plug.

It may cause a fire or an electric shock.

3) Be sure to connect the grounding wire. If an electric leakage

occurs without grounding, a fire or an electric shock may be the

result.

To protect the machine and the power unit from lightening, ground-

ing must be made.

4) When connecting the grounding wire, never connect it to the fol-

lowing points.

It may cause an explosion, a fire or an electric shock.

• Gas tube

• Lightning conductor

• A water pipe or a water faucet, which is not recognized as a

grounding object by the authorities.

• Grounding wire for telephone line

5) Do not damage, brake, or work the power cord.

Do not put heavy objects on the power cable. Do not bend it forc-

ibly or do not pull it extremely.

It may cause a fire or an electric shock.

6) Keep the power cable away from a heat source.

Do not insert the power plug with dust on it into a power outlet.

It may cause a fire or an electric shock.

7) Do not put a receptacle with water in it or a metal piece which may

drop inside the machine.

It may cause a fire or an electric shock.

8) With wet or oily hands, do not touch the power plug, do not insert

the telephone line jack, do not operate the machine, or do not per-

form servicing.

It may cause an electric shock.

3. Note for installing site

Do not install the machine at the following sites.

1) Place of high temperature, high humidity, low temperature, low

humidity, place under an extreme change in temperature and

humidity.

Paper may get damp and form dews inside the machine, causing

paper jam or copy dirt.

For operating and storing conditions, refer to the specifications

described later.

2) Place of much vibrations

It may cause a breakdown.

3) Poorly ventilated place

An electro-static type copier will produce ozone inside it.

The quantity of ozone produced is designed to a low level so as

not to affect human bodies. However, continuous use of such a

machine may produce a smell of ozone. Install the machine in a

well ventilated place, and ventilate occasionally.

4) Place of direct sunlight.

Plastic parts and ink may be deformed, discolored, or may undergo

qualitative change.

It may cause a breakdown or copy dirt.

5) Place which is full of organic gases such as ammonium

The organic photoconductor (OPC) drum used in the machine may

undergo qualitative change due to organic gases such as ammo-

nium.

Installation of this machine near a diazo-type copier may result in

dirt copy.

6) Place of much dust

When dusts enter the machine, it may cause a breakdown or copy

dirt.

7) Place near a wall

Some machine require intake and exhaust of air.

If intake and exhaust of air are not properly performed, copy dirt or

a breakdown may be resulted.

8) Unstable or slant surface

If the machine drops or fall down, it may cause an injury or a break-

down.

If there are optional paper desk and the copier desk specified, it is

recommendable to use them.

When using the optional desk, be sure to fix the adjuster and lock

the casters.

2. Precautions for servicing

1) When servicing, disconnect the power plug, the printer cable, the

network cable, and the telephone line from the machine, except

when performing the communication test, etc.

It may cause an injury or an electric shock.

2) There is a high temperature area inside the machine. Use an

extreme care when servicing.

It may cause a burn.

3) There is a high voltage section inside the machine which may

cause an electric shock . Be careful when servicing.

4) Do not disassemble the laser unit. Do not insert a reflective mate-

rial such as a screwdriver in the laser beam path.

It may damage eyes by reflection of laser beams.

5) When servicing with the machine operating, be careful not to

squeeze you hands by the chain, the belt, the gear, and other driv-

ing sections.
