Removal and replacement strategy

NOTESome photos show a device other than the HP LaserJet M1005 MFP. Repair and

replacement procedures in this chapter are for the HP LaserJet M1005 MFP and are not affected

by cosmetic differences (for example, the color of the covers) shown in these photos.

This chapter documents the removal and replacement of field replaceable parts (FRUs) only.

Reinstallation is generally the reverse of removal. Occasionally, notes and hints are included to provide

directions for difficult or critical replacement procedures.

Admonitions

WARNING!Unplug the power cord from the power outlet (at the wall receptacle) before

attempting to service the device. It this warning is not followed, severe injury can result. Certain

functional checks during troubleshooting must be performed with power supplied to the device.

However, the power supply should be disconnected during removal.

Sheet-metal and plastic edges in the device can be sharp. Use caution when servicing this device.

Never operate or service the device with the protective cover removed from the laser/scanner

assembly. The invisible reflected beam can damage your eyes.

CAUTIONThe device contains components that are sensitive to electrostatic discharge (ESD).

Always perform service work at an ESD-protected workstation. If an ESD-protected workstation

is not available, discharge body static by grasping the print engine chassis before touching an

ESD-sensitive component. Ground the print engine chassis before servicing the device.

CAUTIONDo not bend or fold the FFCs during the removal or reinstallation process.

NOTEFor service purposes, the upper part of the HP LaserJet M1005 MFP is, in effect, the

"scanner" and the lower part is the "printer". Together, they also act as a photocopier, but the

service description here is simplified by referring to copier functionality only when specifically

necessary.

TipTo install a self-tapping screw, first turn it counterclockwise to align it with the existing thread

pattern, then carefully turn it clockwise to tighten. Do not overtighten.

Required tools

●

#2 Phillips screwdriver with magnetic tip

Small flat-blade screwdriver

#8 and #10 torx screwdrivers

Needle-nose pliers

ESD mat (if available)

Penlight (optional)

Long flat-blade screwdriver (optional)

60Chapter 6 Removal and replacementENWW

CAUTIONDo not use a pozidrive screwdriver or any motorized screwdriver. These can damage

screws or screw threads on the device.

Before performing service

●

If possible, print a configuration page (to record customer settings) and menu structure report.

See Troubleshooting tools on page 140.

Remove all media from the device and remove the media input tray. See Media input tray

on page 78.

Turn off the power by using the power switch.

Unplug the power cord from the wall receptacle.

Place the device on an ESD mat, if available. If an ESD-protected workstation is not available,

discharge body static and ground the print engine chassis before servicing the device.

Remove the print cartridge.

After performing service

●

Replace the print cartridge.

Reload the input tray with media.

Restore customer configuration settings.
