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 problem solving. However, the power supply should be disconnected during parts removal.
The sheet-metal parts can have sharp edges. Be careful when handling sheet-metal parts.
CAUTION: Many repair operations will require you to flatten or straighten flex cables. However, where possible, try to avoid doing so. You must make sure that all FFCs are fully seated 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.
Throughout this chapter, the reinstallation process should follow the reverse order of the removal process documented. Where necessary, the tasks include reinstallation tips to aid in the installation of replacement parts.

reminder when removing product parts. Always perform service work at an ESD-protected workstation or mat. If an ESD workstation or mat 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.

Service approach
IMPORTANT: Ensure the product has the latest firmware installed for the initial installation of the product. Certain repairs to this product also require updated firmware, as noted in this document. Download firmware for this product at www.hp.com.
CAUTION: When working on the product, do not pick up the unit by the scanner assembly or output tray. If you need to move the product while performing any service procedures, remove the scanner assembly/output tray to reduce the weight of the product and decrease the chances of damaging the product.
Before performing service
●Remove all paper from the product.
●Turn off the power using the power button.
●Unplug the power cable and interface cable or cables.
●Remove the output bin.
●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 Tray 2 cassette.
●Remove the duplex module, which is located inside the left door.
NOTE: When removing the duplex module, avoid making direct contact with the black cylinder to prevent ink smear on skin or clothes. Keep the duplex module level to avoid spilling any maintenance ink.
After performing service
●Plug in the power cable.
●Reinstall the output bin.
●Reinstall the ink cartridges (if they were removed prior to performing service).
●Reinstall the Tray 2 cassette.

●Reinstall the duplex module.
●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 the necessary reassembly steps have been completed.
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 verify that the expected printing sounds occur.
6.Print a print-quality page, and then verify that there are no lines, streaks, banding, or other print quality defects.
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.
