Removal and replacement strategy
This chapter documents the removal and replacement of field
replaceable units (FRUs) only. Replacement is generally the reverse

directions for difficult or critical replacement procedures.
WARNING! Unplug the power cord from the power source before servicing the
printer. Failure to follow this warning can result in personal injury or

Never operate the printer with the laser/scanner assembly exposed.
The reflected beam, although invisible, can damage your eyes. When
servicing the printer, replace the top cover before operating the printer.
