The following precautions must be observed when handling P.W

(Metal Oxide Semiconductor) ICs.

During Transportation/Storage:

• During transpor tation or when in storage, new P.W. Boards must

removed from their protective conductive bags.

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

• When it becomes absolutely necessary to remove a Board from i

case, always place it on its conductive mat in an area as free as p

tricity.

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

During Replacement:

• Before unplugging connectors from the P.W. Boards, make sure t

been unplugged from the outlet.

• When removing a Board from its conductive bag or conductive ca

pins of the ICs or the printed pattern. Place it in position by holdin

Board.• Before plugging connectors into the Board, make sure that the po

unplugged from the power outlet.

During Inspection:

• Avoid checking the IC directly with a multimeter; use connectors o

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

• When it is absolutely necessary to touch the ICs and other electri

PW Board, be sure to ground your body.

During Transportation/Storage:

• Use the specified carton whenever moving or storing the Imaging

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

• In summer, avoid leaving the Imaging Cartridge in a car for a long
