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.

Turning the power off by using the On/Off switch does 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.

Do not touch any electrical component unless you are instructed to do so by a

service procedure.

When servicing mechanical components within the printer, manually rotate drive

assemblies, rollers, and gears.

Do not try to manually rotate or manually stop the drive assemblies while any

printer motor is running.
