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.

2 Chapter 1 Removal and replacement ENWW

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-inch) shaft length

●

Small flat-blade screwdriver

●

Torx screwdriver, size 6

●

Needle-nose pliers

●

ESD mat (if one is available) or ESD strap

●

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.

which print cartridge is in the opening.

8 Chapter 1 Removal and replacement ENWW

panel, touch the Supplies

button.

and the rotation sounds stop, and then open the print-cartridge door.

handle and remove it.

9. Remove the new print cartridge from the

packaging. Place the used print cartridge in the bag and box for recycling.

CAUTION: To prevent damage to the print

cartridge, hold the print cartridge at each end. Do not touch the roller on the print cartridge.

10. Grasp both sides of the new print cartridge

and gently rock it to distribute the toner evenly.

cartridge to the color label in the carousel slot to make sure the print cartridge color matches the carousel position. (The black carousel position has no label.)

CAUTION: If toner gets on your clothing,

wipe it off with a dry cloth and wash the clothing in cold water. Hot water sets toner into the fabric.

14. Close the print cartridge door.

NOTE: After closing the print cartridge door,

the control panel shows the Calibrating... message. Allow a few minutes for the product to calibrate.

cartridge, you must close the print cartridge door before touching the Cartridge Rotate button again.

You do not need to wait for the product to calibrate when replacing the second print cartridge. Instead, touch the Cartridge Rotate button to rotate the carousel into position. After you have replaced the print cartridges, the product calibrates.
