2. How to use this book
Repairs and adjustments
•
To reassemble the product, reverse the order of disassembly unless otherwise specified.
Troubleshooting
•
If a component on a PWB or any other functional unit including a motor is defective, the text
only instructs you to replace the whole PWB or functional unit and does not give troubleshoot-
ing procedures applicable within the defective unit.
•
All troubleshooting procedures contained herein assume that there are no breaks in the har-
nesses and cords and all connectors are plugged into the right positions.
•
The procedures preclude possible malfunctions due to noise and other external causes.
3. Precautions for service
•
Keep all removed parts in good order and keep tools under control so that none will be lost or
damaged.
•
After completing a service job, perform a safety check. Make sure that all parts, wiring and
screws are returned to their original positions.
•
Do not pull out the toner hopper while the toner bottle is turning. This could result in a dam-
aged motor or locking mechanism.
4. Precautions for dis/assembly
•
Be sure to unplug the machine from the outlet before attempting to service the machine.
•
The basic rule is not to operate the machine any time during disassembly. If it is absolutely
necessary to run the copier 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, make sure that the power cord of the machine has been
unplugged from the wall outlet.
•
While the product is powered on, do not unplug or plug connectors into the circuit boards or
harnesses.
•
Never use flammable sprays near the copier.
•
When reassembling parts, make sure that the correct screws (size, type) and lock 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 PWB’s
During transportation/storage
•
During transportation or when in storage, new PWB’s must not be indiscriminately removed
from their protective conductive bags.
•
Do not store or place PWB’s in a location exposed to direct sunlight and high temperature.
