1-2. 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.
Durtng Inspection:
© Avoid checking the IC directly with a multimeter; use connectors on the Board.
@ Never create a closed circuit across !C pins with a metal tool.
® When it is absolutely necessary to touch the ICs and other alectrical components on the Board, be sure
to ground your body.

1-3. 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.
@ [n 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 oijl-base solvent, fingerprints, and other for-
. eign 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.
