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.
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.

ENWW |
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.
●#2 Phillips screwdriver with a magnetic tip and a 152-mm (6-in) 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.
Figure 1-1 Phillips and Pozidriv screwdriver comparison
●Remove all paper 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 print cartridge.
ENWW |
Electrostatic discharge 3 |
●Plug in the power cable.
●Reinstall the print cartridge.
●Load paper in the product.
Perform the following test to verify that the repair or replacement was successful.
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 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.Clean the outside of the product with a damp cloth.
Use the following diagram to determine which parts must be removed before removing other parts.

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.
1.Open the front door and pull out the print-cartridge drawer.
2.Grasp the handle on the print cartridge, and then pull the cartridge straight up to remove it. Repeat this step for the remaining print cartridges.
CAUTION: Do not touch the imaging drum on the bottom of the print cartridge. Finger prints on the imaging drum can cause print-quality problems.
Do not allow the image drum to contact any surface when the cartridges are set down. Protect the image drum at all times. Dust and debris can stick to the drum and cause print-quality problems.
Figure 1-3 Remove the print cartridge
3.Close the print-cartridge and front doors.

Removal and replacement procedures 5 |
CAUTION: Do not touch the spongy roller surface unless you are going to replace the roller. Skin oils on the roller can cause paper pickup problems.
1.Use the following procedure to rotate the roller into the position required to remove it.
●Open the Secondary Service menu by pressing and holding both the Left arrow () and the Cancel button simultaneously.
●Use the arrow buttons to select Pick roller, and then press the OK button.
●Press the OK button again to confirm that you want the pick roller to rotate.
●Turn the power off.
2.Remove Tray 2, and then carefully place the product front-side up.
NOTE: Debris can scratch or damage the back of the product. Before you place the product front-side up, remove any debris from the work surface. If possible, set the product on a clean, dry cloth to prevent scratching and damage.
3.Release the two white plastic locking tabs and remove the pickup roller.

CAUTION: Do not touch the spongy roller surface unless you are going to replace the roller. Skin oils on the roller can cause paper pickup problems.
1.Remove paper tray (if installed), and then carefully place the product front-side up.
NOTE: Debris can scratch or damage the back of the product. Before you place the product front-side up, remove any debris from the work surface. If possible, set the product on a clean, dry cloth to prevent scratching and damage.
2.Carefully release the roller cover and rotate it down and away from the roller.
Reinstallation tip Make sure that this cover snaps into place over the roller when the roller and holder are reinstalled.
