@Bernie741, Welcome to the HP Support Community! I’m here to help.


Not all HP printers have a removable printhead. Check if the printhead has a latch towards the right corner.

If your printer has a removable printhead, you can manually reseat it. Otherwise use the steps provided to replace the printhead or service the printer.

  1. Open the door or lid to the cartridge access area. Wait until the carriage stops moving before continuing.

  2. Look for a latch on the carriage.

    • If there is no latch, the printhead is not replaceable. Go to Contact HP Customer Support to schedule a product repair or replacement. If you are in Asia Pacific, you will be directed to a local service center in your area. To confirm your warranty status, go to HP Product Warranty Check. Repair fees might apply for out-of-warranty products.

    • If there is a latch, continue to the next step.

  3. With the printer turned on, disconnect the power cord from the printer.

  4. Lift the carriage latch, slightly lift the printhead, lower the printhead back into the carriage, wiggle the printhead left and right, and then lower the carriage latch until it stops.

  5. Close the door or lid to the cartridge access area.

  6. Reconnect the power cord to the printer.

    If the error message still displays, sometimes the issue persists after inserting the printhead. Repeat the steps to reseat the printhead up to three times, and then continue to the next step if the error still displays.

Please reach out to HP Support in your region regarding the service options for your printer. 


If the printer is out of warranty, I suggest you upgrade the printer. You may visit Hp Store to check the available printers.
