Service Precautions
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.
• Do not 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 gears, rollers, and fan motor.
• Never touch the terminals of electrical parts or high-voltage
parts such as the high voltage power supply board.
• 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 listed in the parts catalog.
• Do not forget to install the ground wire or ground plate to ensure
positive conduction. Install the screw with a toothed washer in
the correct position at reassembly.
