NOTE: Your product might not appear exactly as the one shown in the photos in this chapter. Although some photos do not show the ADF/scanner unit, the procedures in this chapter are appropriate for your product.

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

General cautions during removal and replacement

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.

WARNING! Turn the product off, wait 5 seconds, and then remove the power cable 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 prefolds 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 Printed Circuit Assembly (PCA).

NOTE: To install a self-tapping screw, first turn it counterclockwise to align it with the 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.

Note the length, diameter, color, type, and location of each screw. Be sure to return each screw to its original location during reassembly.

Chapter 1 Removal and replacement

ENWW

TIP: For clarity, some photos in this chapter might 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

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

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

●Small flat blade screwdriver

●Needle-nose pliers

●ESD mat or ESD strap (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.

Service approach

Product repair normally begins by using the product internal diagnostics and the following two-step process:

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

2.Troubleshoot the problem by using the procedures in the solve problems chapter.

After you find a faulty part, the product can usually be repaired at the assembly level by replacing fieldreplaceable units (FRUs). Some mechanical assemblies might need to be repaired at the subassembly level.

Before performing service

●Remove all media from the product.

●Turn off the power using the power switch.

●Unplug the power cable and interface cable or cables.

●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 cartridges. See Toner cartridges on page 9.

●Remove the tray or trays. See Tray 2 and 3 on page 14.

After performing service

●Plug in the power cable.

●Reinstall the toner cartridges.

●Reinstall the tray or trays.

●If the optional paper feeder was installed, place the product on the feeder.

Service approach

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 trays contain clean, unmarked paper.

3.Attach the power cord and 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.

7.Send a print job from the host computer, and then verify that the output meets expectations.

8.If necessary, restore any customer-specified settings.

9.Clean the outside of the product with a damp cloth.

Copy-quality test

1.Verify that you have completed the necessary reassembly steps.

2.Ensure that the input tray contains clean, unmarked paper.

3.Attach the power cord, and then turn on the product.

4.Verify that the expected start-up sounds occur.

5.Print a configuration page, and then verify that the expected printing sounds occur.

6.Place the configuration page in the Automatic Document Feeder (ADF).

7.Print a copy job, and then verify the results.

8.Place the configuration page on the scanner glass.

9.Print a copy job, and then verify the results.

10.Clean the outside of the product with a damp cloth.
