1 SERVICE INSTRUCTIONS

1-1. INSTRUCTIONS FOR HANDLING THE PWBs WITH MOS ICs

The following precautions must be observed when handling P.W. Boards with MOS
(Metal Oxide Semiconductor) ICs.

During Transportation/Storage:

•

During transportation or when in storage, new P.W. Boards must not be indiscriminately
removed from their protective conductive bags.

•

Do not store or place P.W. Boards in a location exposed to direct sunlight.

•

When it becomes absolutely necessary to remove a Board from its conductive bag or
case, always place it on its conductive mat in an area as free as possible from static elec­tricity.

•

Do not touch the pins of the ICs with your bare hands.

During Replacement:

•

Before unplugging connectors from the P.W. Boards, make sure that the power cord has
been unplugged from the outlet.

•

When removing a Board from its conductive bag or conductive case, do not touch the
pins of the ICs or the printed pattern. Place it in position by holding only the edges of the
Board.

•

Before plugging connectors into the Board, make sure that the power cord has been
unplugged from the power outlet.

During Inspection:

•

Avoid checking the IC directly with a multimeter; use connectors on the Board.

•

Never create a closed circuit across IC pins with a metal tool.

•

When it is absolutely necessary to touch the ICs and other electrical components on the
Board, be sure to ground your body.

1-2. HANDLING OF THE PC DRUM

During Transportation/Storage:

•

Use the specified carton whenever moving or storing the PC Drum.

•

The storage temperature is in the range between –20°C and +40°C.

•

In summer, avoid leaving the PC Drum in a car for a long time.

Handling:

•

Ensure that the correct PC Drum is used.

•

Whenever the PC Drum has been removed from the copier, store it in its container or pro­tect it with a Drum Cloth.

•

The PC Drum exhibits greatest light fatigue after being exposed to strong light over an
extended period of time. Never, therefore, expose it to direct sunlight.

•

Use care not to contaminate the surface of the PC Drum with oil-base solvent, finger­prints, and other foreign matter.

•

Do not scratch the surface of the PC Drum.

•

Do not apply chemicals to the surface of the PC Drum.

•

Do not attempt to wipe clean the surface of the PC Drum.

D-1

FrameMaker Ver.5.5(PC) EP1054/EP1085/EP2030 DIS/REASSEMBLY, ADJUSTMENT

98.04.13

If, however, the surface is contaminated with fingerprints, clean it using the following proce­dure.

1. Place the PC Drum into one half of its container.

1076D001

2. Gently wipe the residual toner off the surface of the
PC Drum with a dry, Dust-Free Cotton Pad.

A. Rotate the PC Drum so that the area of its surface

on which the line of toner left by the Cleaning
Blade is present is facing straight up. Wipe the sur­face in one continuous movement from the rear
edge of the PC Drum to the front edge and off the

1076D002

surface of the PC Drum.

B. Rotate the PC Drum slightly and wipe the newly

exposed surface area with a CLEAN face of the
Dust-Free Cotton Pad. Repeat this procedure until
the entire surface of the PC Drum has been thor­oughly cleaned.

✽

At this time, always use a CLEAN face of the dry
Dust-Free Cotton P ad until no toner is e vident on the
face of the Pad after wiping.

1076D003

1076D004

3. Soak a small amount of either ethyl alcohol or iso­propyl alcohol into a clean, unused Dust-Free Cot­ton Pad which has been folded over into quarters.
Now, wipe the surface of the PC Drum in one con­tinuous movement from its rear edge to its front
edge and off its surface one to two times.

✽

Never move the Pad back and forth.

4. Using the SAME face of the Pad, repeat the proce­dure explained in the latter half of step 3 until the
entire surface of the PC Drum has been wiped.
Always OVERLAP the areas when wiping. Two
complete turns of the PC Drum would be appropri­ate for cleaning.

98.04.13

NOTES

•

The Organic Photoconductor Drum is softer than CdS and Selenium Drums and is there­fore susceptible to scratches.

•

Even when the PC Drum is only locally dirtied, wipe the entire surface.

•

Do not expose the PC Drum to direct sunlight. Clean it as quickly as possible even under
interior illumination.

•

If dirt remains after cleaning, repeat the entire procedure from the beginning one more
time.
