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 HP
LaserJet 1100. If this warning is not followed, severe injury can result. Certain functional
checks must be performed during troubleshooting with power supplied to the product.
However, the power supply should be disconnected during removal.
Never operate or service the HP LaserJet 1100 with the protective cover removed from
the laser/scanner assembly. The reflected beam, although invisible, can damage your
eyes.
The sheet metal edges of the HP LaserJet 1100 can be sharp. Use caution when
working the HP LaserJet 1100.
CAUTION
The HP LaserJet 1100 contains parts that are electrostatic discharge (ESD) sensitive.
Always perform servicing at an ESD-protected workstation.
Note
To install a self-tapping screw, first turn it counterclockwise 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.
Always remove the toner cartridge before removing or replacing parts.
