Removal and cleaning 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 removal unless
otherwise specified.
•
Do not operate the printer anytime during removals. 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.
•
Remove the ground wire when removing or replacing the low
voltage power supply. After installation is complete, confirm the
ground wire is reconnected to the earth mark
.
•
After part replacement, ensure the wiring harness is not caught
or damaged.
•
Do not attempt to cut or extend the wiring harness.
•
Confirm the wiring harness connector is connected properly.
•
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.
•
Remember 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.
