Hi @Louise2679 

Welcome to the HP Support Community! 

Thanks for posting your query! We're here to help you get back up and running.

Perform the following tasks in the order given to resolve the print quality issue with your printer. Use the printer after each task to see if the issue is resolved.

Clean the printhead (HP Smart app)

Clean the ink smears (HP Smart app)

Check ink cartridges

Very low ink levels, using non-HP cartridges, and rough handling can cause print quality issues. 

Check the paper, print settings, and quality of the file being printed

Print an alignment page with the HP Smart App

Thank you for updating me @Louise2679. 

I understand that all recommended methods have already been tried and the issue remains unresolved. It’s good to know you’ve ordered a replacement print head—once it arrives and is installed, that should help determine if the problem is indeed with the print head itself.

Keep me posted for any further assistance.

I changed the printhead, even though I did not have a printhead message on the touch display.  After I replaced the printhead and before snapping into place that is when the printhead error message appeared.  Then i followed the message on the display.  Completing the process of alignment.  The color blue has returned.

It sounds like you’ve successfully resolved the issue with your printer after replacing the printhead. Even though the printer didn’t initially show a printhead error, swapping it out triggered the system to recognize the new hardware, which is why the error message appeared at that stage. 

Following the alignment process was the right move — alignment ensures the new printhead is calibrated correctly with the printer’s mechanics and ink flow.

The fact that the blue color has returned is a strong sign that the printhead replacement and alignment worked as intended. If you notice any further color inconsistencies, running another alignment or a printhead cleaning cycle from the printer’s maintenance menu can help fine-tune the output.

If you have any more questions or need further assistance, please don't hesitate to ask. We're here to help! 

Thanks again for your confirmation, and we wish you an amazing day ahead! 😊
