HP LaserJet 5P Printer Service Supplement Removal and Replacement Removal and Replacement Overview The removal and replacement procedures for many HP LaserJet 5P printer Field Replaceable Units (FRUs) are identical to the HP LaserJet 4L and 4P printers. This section describes only those differences unique to the HP LaserJet 5P for removing: • Power Door • I/O Cover • Left Side Cover • Top Cover • Tray 1 Pickup Assembly • Formatter Board Assembly • Fuser Assembly • DC Controller Assembly 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. 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 over-tighten. If a self-tapping screw-hole becomes stripped, repair of the screw-hole or replacement of the affected assembly is required. 37
