HP Designjet 1000 Series Printers - Printhead Rejection Issues


This document does not apply to REPLACE messages.
The printer's carriage does not accept one or more of the printheads. Typical causes are dirty electrical contacts on the printheads or carriage, or the printhead(s) themselves. Use the information below to determine the cause of the failure and perform the necessary troubleshooting steps to resolve.

Troubleshooting steps

  1. Turn the printer on.
  2. Allow printer to complete initialization.
  3. With the ink droplets icon highlighted, press Enter.
  4. Select Replace Printheads and press Enter.
  5. If the message Printheads still functional appears, scroll to Yes (Replace) and press Enter.
  6. Open the top cover.
  7. Turn the printer off.
  8. Clean the electrical contacts on the carriage and the printheads using the steps provided below.
  9. When the contacts are dry, reinstall the printheads and close the carriage cover.
  10. Close the top cover.
  11. Turn the printer on.
  12. If the error returns, replace the affected printhead(s).
    If the Printhead error icon is a question mark, each Printhead will have to be tested separately as the printer is not sure which one is causing the problem.
  13. Following replacement of the suspect printhead(s), attempt to verify functionality.
  14. If the problem persists, contact HP.

Cleaning the carriage and printhead contacts

It is recommended that a cleaning kit (HP part number C6071-60153) be used to clean the printhead and carriage contacts. The cleaning kit contains the following:
  • The Carriage Interconnect Wiper
  • A flyer with User Information
  • 15-20 Replacement sponges
The cleaning kit can be ordered by calling HP Parts store at (800) 227-8164, or by clicking here to access HP Parts store at http://www.hp.com/buy/parts. Order HP part number C6071-60153.
If a cleaning kit is not available, use a lint-free cloth (i.e. an old T-shirt) lightly dampened with water to perform the cleaning steps outlined below.

Preparing the carriage interconnect wiper for use

  1. Remove the carriage interconnect wiper and one of the replacement sponges from the package.
