Hi @Leiv,
Welcome to HP Support Community.
Thank you for posting your query, I will be glad to help you.
Resolve errors such as Incompatible printhead, Missing or failed printhead, and Printhead problem for Officejet printer.
Perform the following tasks in the order given. Use the printer after each task to see if the issue is resolved.
Reset the printer
- Reset the printer to recover from printer errors or failures.
- If your printer has a rechargeable battery, remove it.
- Press the power button to turn off the printer. If the printer does not turn off, disconnect the power cord from the printer.
- Unplug the power cord from the power source.
- Wait 60 seconds.
- Connect the power cord directly to a wall outlet and to the printer.
- Turn on the printer to complete the reset.
Clean or service the printhead
- If your printer has a removable printhead, you can manually clean it. Otherwise use the steps provided to replace the printhead or service the printer.
- Open the door or lid to the cartridge access area. Wait until the carriage stops moving before continuing.
- 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 the error still displays, continue to the next step.
- Go to the HP Parts Store.

- If your printer uses four ink cartridges, search for CN643A.
- If your printer uses five ink cartridges, search for CN642A.
- Follow the steps to order the printhead.
- NOTE:
