Introduction

This document contains steps for replacing the printhead in your HP printer.

Ordering the printhead assembly

If you have a defective cartridge or printhead, it might be under warranty. To check the warranty on your ink or toner supplies, go to Printer and Page Yield Overview, and then review the limited warranty information for your supplies.
  1. If you are in Asia Pacific, the site directs you to a service center in your area.
  2. Search for part number CN643A.
  3. Follow the instructions to order the printhead assembly.

Replacing the printhead assembly

Follow these steps to replace the printhead assembly.
Important: Do not remove the original printhead until you are ready to install the new printhead. Doing so might result in ink system failures. When you remove the original printhead, insert the new printhead and cartridges within five minutes.

Step one: Load paper

  6. Use the pre-moistened wipes that come with the printhead assembly to clean the electrical contacts inside the printer.
    Wipe from the top to the bottom of the electrical contacts, in one direction only. As the wipes become dirty, discard them, and then open new ones.
      注意:
    Do not wipe up and down or side to side, as doing so can damage the printer.

Step three: Return failed parts to HP

HP analyzes the failed parts to improve its printers in the future. If the new printhead assembly came with a prepaid mailing label and return instructions, follow these steps to return the failed parts to HP.
補足:
HP does not ask that all failed parts be returned, so you might have a prepaid mailing label and return instructions. You can ignore these steps if you did not receive the return documents.
  1. Put the old printhead assembly into the package that the new part came in.
