Removal and replacement strategy

Introduction

The printer uses a fiel repair strategy. Defective parts are diagnosed and replaced at the Field Replaceable Unit (FR

U) assembly level. Repair normally begins by using the printer internal diagnostics and the following two-

step process:

1. Isolate the problem to the major system (for example, the network, server, or printer).

2. Identify the cause of failures according to the printer troubleshooting service manual and follow the

disas

sembly procedures to replace the defective parts or the consumable parts.

After locating a faulty part, the printer can usually be repaired at the assembly level by replacing FRUs. Some mechanical assemblies might need to be repaired at the subassembly level. HP does not support replacement of components on the printed circuit assembles.

The user replaces toner cartridges as they are depleted. Additional instructions about other user-replaceable parts are provided in this section.

The printer tracks the amount of use on the user-replaceable supplies by keeping a page count. The printer prompts the user to replace certain items when a supply is depleted or a specifi number of pages has been printed.

Swapping toner cartridges between products might cause a misrepresentation of supply life values and is not recommended.

Considerations during removal and replacement

This chapter describes the FRUs only.

Replacing FRUs is generally the reverse of removal. Notes are included to provide directions for difficu or critical repl

acement procedures.

HP does not support repairing individual subassemblies or troubleshooting to the printed-circuit assembly (PCA) component level.

WARNING! Never operate or service the printer with the protective cover removed from the laser scanner

sembly. The reflecte beam, although invisible, can cause damage to the eyes.

The sheet-metal parts can have sharp edges. Be careful when handling sheet-metal parts.

Turn the printer this warning is not followed, severe injury can result as well as damage to the printer. The power must be on for certain functional checks during troubleshooting. However, the power cord must be disconnected during parts removal. AC voltage is still present inside the printer when the power switch is in the o position. The power cord must be disconnected before servicing the printer.

CAUTION: Incorrectly routed or loose wire harnesses might interfere with other internal components or

assemblies and be damaged, pinched, or frayed. Make sure that wire harnesses are correctly routed and retained when installing assemblies.

Do not bend or fold the fla flexibl cables (FFCs) during removal or installation.

Do not expose the toner cartridge, or cartridges, to strong light even for a short time.

IMPORTANT: When an assembly is removed that includes a rating plate or tag (or a printer code label), make

sure to transfer the plate or tag (or code label) to the replacement assembly.

Do not replace the formatter, DC controller, memory PCA (island of data), and eMMC PCA or hard-disk drive simultaneously during a single printer servicing. Doing so might cause the printer to become unstable or inoperable.

NOTE: During assembly removal and replacement, or if the printer is moved, remove the toner cartridge or

cartridges.

Toner is a non-poisonous substance composed of plastic and a small number of colored components. If toner gets on the skin or clothing, wipe it o with dry tissue paper and wash in cold water. Hot water sets toner and it might be difficul or impossible, to remove. Toner easily breaks down vinyl materials, so avoid letting toner contact vinyl.

TIP: Some figure might show assemblies removed or installed that have not yet been removed or installed at

that specifi step. However, the procedures are correct for this printer and the target assembly. Always thoroughly read the instructions that accompany each figure

Electrostatic discharge

CAUTION: Some parts are sensitive to electrostatic discharge (ESD). Look for the ESD reminder when

removing printer parts. Always perform service work at an ESD-protected workstation or mat. If an ESD workstation or mat is not available, touch the sheet-metal chassis to provide a static ground before touching an ESD-sensitive assembly.

Protect the ESD-sensitive assemblies by placing them in ESD pouches when they are out of the printer.

Required tools

● #2 Phillips screwdriver with a magnetic tip and a 152-mm (6-in) shaft length

● Small,

● Needle-nose pliers

● ESD strap (if one is available)

● Penlight

CAUTION: Always use a #2 Phillips screwdriver (callout 1). Do not use a Pozidriv screwdriver (callout 2) or any

torized screwdriver. These can damage screws or screw threads.

WARNING! Make sure that assemblies are replaced with the correct screw type. Using the incorrect screw (for

ample, substituting a long screw for the correct shorter screw) can cause damage to the printer or interfere

ex with printer operation. Do not intermix screws that are removed from one assembly with the screws that are removed from another assembly.

NOTE: To install a self-tapping screw, firs turn it counterclockwise to align it with the existing thread pattern,

and then careful repair the screw hole or replace the affecte assembly.

Always take note of the length, diameter, color, type, and location of each removed screw. Make sure that

ws are installed in their original location during reinstallation.

Service approach

Before performing service

WARNING! Turn the printer off wait 30 seconds, and then remove the power cord before attempting to service

the printer. If this warning is not followed, severe injury and damage to the printer can result. The power must be on for certain functional checks during troubleshooting. However, the power to the printer should be disconnected during parts removal.

1. Remove all paper.

2. Place the printer on an ESD mat (if available). If an ESD workstation or mat is not available, touch the sheet-

metal chassis to provide a static ground before touching an ESD-sensitive assembly.

3. Remove the toner cartridge or toner cartridges and place a sheet of paper over the exposed drums to

protect them from excessive light exposure.

4. Remove the trays.

After performing service

1. Reinstall the toner cartridge or toner cartridges.

2. Reinstall the trays.

3. Return all paper to the trays.

4. Plug in the power cable and turn on the printer.

5. Perform print-quality tests by printing from a host computer or by printing internal configuratio and demo

pages.

Post service tests
