Removal and replacement strategy
This chapter documents removal and replacement of Field Replaceable Units (FRUs) only.
Replacement is generally the reverse of removal. Occasionally, notes are included to provide
direction for difficult or critical replacement procedures.
WARNING! Unplug the power cord from the power outlet before attempting to service the printer. If this warning
is not followed, severe injury may result.
Never operate or service the printer with the protective cover removed from the Laser/Scanner
Assembly. The reflected beam, although invisible, can damage your eyes.
The sheet metal edges of this printer can be sharp! Exercise caution when working with the printer.
CAUTION The printer contains parts that are electrostatic discharge (ESD) sensitive. Always service printers at
an ESD-protected workstation.
To install a self-tapping screw, first turn it counter-clockwise to align it with the existing thread pattern,
then carefully turn clockwise to tighten. Do not overtighten. If a self-tapping screw-hole becomes
stripped, repair the screw-hole or replace the affected assembly.
Note Always remove the toner cartridge before removing or replacing parts.
