PagePro 1200 Series Safety

4. Precautions for Dis/Reassembly

• Be sure to unplug the printer from the outlet before attempting to service the printer.

• Generally, do not to operate the printer anytime during disassembly. If it is absolutely necessary

to run the printer with its covers removed, use care not to allow your clothing to be caught in

revolving parts such as the timing belt and gears.

• Before attempting to replace parts and unplug connectors, make sure that the power cord of the

printer has been unplugged from the wall outlet.

• While the product is energized, do not unplug or plug connectors into the circuit boards or har-

nesses.

• Never use flammable sprays near the printer.

• A used battery should be disposed of according to the local regulations and never be discarded

casually or left unattended at the user’s premises.

• When reassembling parts, make sure that the correct screws (size, type) and toothed washer are

used in the correct places.

5. Precautions for Circuit Inspection

• Never create a closed circuit across connector pins except those specified in the text and on the

printed circuit.

• When creating a closed circuit and measuring a voltage across connector pins specified in the text,

be sure to use the GND wire.

6. Handling of PWBs

During Transportation/Storage

• P.W. Boards should be left in antistatic bags during transportation and storage.

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

• 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.

• Protect the PWBs from any external force so that they are not bent or damaged.

During Inspection/Replacement

• 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.

• 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.

• When touching the PWB, wear a wrist strap and connect its cord to a securely grounded place

whenever possible. If you cannot wear a wrist strap, touch a metal part to discharge static electric-

ity before touching the PWB.

• Note that replacement of a PWB may call for readjustments or resetting of particular items.

7. Handling of Other Parts

• The magnet roller generates a strong magnetic field. Keep it away from watchs, floppy disks,

magnetic cards, or CRT tubes.

8. Handling of the Imaging Cartridge

During Transportation/Storage

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

• Do not leave the Imaging Cartridge in a hot car for an extended period of time.

Handling

• Store the Imaging Cartridge in a place that is not exposed to direct sunlight.
