Servicing Electrical Components
Before starting any service procedure, switch off the printer power and unplug the power cord
from the wall outlet. If you must service the printer with power applied, be aware of the
potential for electrical shock.
Warning: Turning the power off by using the On/Off switch may not completely de-energize
the printer. You must also disconnect the printer power cord from the AC outlet. Position the
power cord so that it is easily accessible during servicing.
Warning: Do not touch any electrical component unless you are instructed to do so by a
service procedure.
The following are hazards to your safety:
■ The power cord is damaged or frayed.
■ Liquid is spilled into the printer.
■ The printer is exposed to water.
If any of these conditions occur, do the following:
■ Turn off the printer immediately.
■ Disconnect the power cord from the electrical outlet.
Servicing Mechanical Components
Caution: When servicing mechanical components within the printer, manually rotate drive
assemblies, rollers, and gears.
Warning: Do not try to manually rotate or manually stop the drive assemblies while any
printer motor is running.
Warning: This printer uses heat to fuse the toner image to media. The Fuser Assembly is
VERY HOT. Turn the printer power off and wait at least 5 minutes for the Fuser to cool before
you attempt to service the Fuser Assembly or adjacent components.
