Precautions for Disassembly and Cleaning
Observe the following precautions whenever you service the printer:
•
Be sure to unplug the printer from the outlet before attempting
to service the printer.
•
To reassemble the printer, reverse the order of disassembly
unless otherwise specified.
•
The basic rule is not to operate the printer anytime during disas-
sembly. 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 gears, rollers and fan
motor.
•
Never touch the terminals of electrical parts or high-voltage
parts such as the high voltage unit.
•
Be sure to handle the fuser carefully as it remains hot for a while
after the printer stops running. Always unplug connectors by
holding the connector housing.
•
Be sure to use the fuse of the specified rating.
•
Do not forget to install the ground wire or ground plate to ensure
positive conduction. Install the screw with a toothed washer in
the right position at reassembly.
Instructions for Handling the PWBs with MOS ICs
The following precautions must be observed when handling circuit
boards with MOS (Metal Oxide Semiconductor) ICs.
During Transportation/Storage:
•
During transportation or when in storage, new circuit boards
must not be indiscriminately removed from their protective con-
ductive bags.
•
Do not store or place circuit 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 pins of the ICs with your bare hands.
