Removal and replacement strategy
Introduction
This chapter describes the removal and replacement of field-replaceable units (FRUs) only.
Replacing FRUs is generally the reverse of removal. Occasionally, notes and tips are included to
provide directions for difficult or critical replacement procedures.
HP does not support repairing individual subassemblies or troubleshooting to the component level.
Note the length, diameter, color, type, and location of each screw. Be sure to return each screw to its
original location during reassembly.
Incorrectly routed or loose wire harnesses can interfere with other internal components and can become
damaged or broken. Frayed or pinched harness wires can be difficult to find. When replacing wire
harnesses, always use the provided wire loops, lance points, or wire-harness guides and retainers.
Removal and replacement strategy
WARNING! Turn the product off, wait 5 seconds, and then remove the power cord before
attempting to service the product. If this warning is not followed, severe injury can result, in addition to
damage to the product. The power must be on for certain functional checks during troubleshooting.
However, disconnect the power supply during parts removal.
Never operate or service the product with the protective cover removed from the laser/scanner
assembly. The reflected beam, although invisible, can damage your eyes.
The sheet-metal parts can have sharp edges. Be careful when handling sheet-metal parts.
CAUTION: Do not bend or fold the flat flexible cables (FFCs) during removal or installation. Also, do
not straighten pre-folds in the FFCs. You must fully seat all FFCs in their connectors. Failure to fully seat
an FFC into a connector can cause a short circuit in a PCA.
NOTE: To install a self-tapping screw, first turn it counterclockwise to align it with the existing thread
pattern, and then carefully turn it clockwise to tighten. Do not overtighten. If a self-tapping screw-hole
becomes stripped, repair the screw-hole or replace the affected assembly.
TIP: For clarity, some photos in this chapter show components removed that would not be removed to
service the product. If necessary, remove the components listed at the beginning of a procedure before
proceeding to service the product.
Electrostatic discharge
CAUTION: Some parts are sensitive to electrostatic discharge (ESD). Look for the ESD reminder
when removing product parts. Always perform service work at an ESD-protected workstation or mat, or
use an ESD strap. If an ESD workstation, mat, or strap is not available, ground yourself by touching the
sheet-metal chassis before touching an ESD-sensitive part.
Protect the ESD-sensitive parts by placing them in ESD pouches when they are out of the product.

Required tools
#2 Phillips screwdriver with a magnetic tip and a 152 mm (6 in) shaft length
●
Precision slotted screwdriver with a 1 mm (0.04 in) blade width
●
NOTE: This fine-point tool is required to release the front-door pins. The width of the blade must
be 2 mm (0.08 in) or less to be able to push the door pins out of the mounting holes.
Small slotted screwdriver
●
Needle-nose pliers
●
ESD mat (if one is available)
●
Penlight (optional)
●
CAUTION: Always use a Phillips screwdriver (callout 1). Do not use a Pozidriv® screwdriver
(callout 2) or any motorized screwdriver. These can damage screws or screw threads.

WARNING! Make sure that components are replaced with the correct screw type. Using the
incorrect screw (for example, substituting a long screw for the correct shorter screw) can cause damage
to the product or interfere with product operation. Do not mix screws that are removed from one
component with the screws that are removed from another component.
NOTE: The screw illustrations in the following table are for reference only. Screws might vary in size
and appearance from those shown in this table.

Service approach
Before performing service
Remove all paper from the product.
●
Turn off the power using the power switch.
●
Unplug the power cable and the interface cable or cables.
●
4 Chapter 1 Removal and replacement ENWW
Place the product on an ESD workstation or mat, or use an ESD strap (if one is available). If an
●
ESD workstation, mat, or strap is not available, ground yourself by touching the sheet-metal
chassis before touching an ESD-sensitive part.
Remove the toner cartridge.
●
CAUTION: Do not touch the imaging drum on the bottom of the toner cartridge. Finger prints on
the imaging drum can cause print-quality problems.
Do not allow the image drum to contact any surface when the cartridge is set down. Protect the
image drum at all times. Dust and debris can stick to the drum and cause print-quality problems.
After performing service
Plug in the power cable.
●
Reinstall the toner cartridge.
●
Load paper in the product.
●
Post-service test
Perform the following test to verify that the repair or replacement was successful.
Print-quality test
1. Verify that you have completed the necessary reassembly steps.
2. Make sure that the tray contains clean, unmarked paper.
3. Attach the power cord and the interface cable or interface cables, and then turn on the product.
4. Verify that the expected startup sounds occur.
5. Print a configuration page, and then verify that the expected printing sounds occur.
6. Print a demo page, and then verify that the print quality is as expected.
