Even after 3 printhead cleanings and printhead alignment I still have blank horizontal lines.

[Bob3355]

Poor page printout quality as described above after doing all the printhead cleaning and aligning.  This happened for a while but always "cleaned up". Now no more improvement.  Message on printer says may need new printhead.  How do I know for sure? and what is the part number?  Thanks.

Hi @Bob3355,

Welcome to the HP Support Community.

Thank you for posting your query. I will be glad to assist you.

I see that you are facing an issue with your printer that has horizontal lines while printing.

Make a copy on the printer standalone and let me know if you have horizontal lines? (Place an original document on the scanner glass and make a copy to confirm hardware is working fine)

To understand the issue and help you, please share the details listed below:

- May I know which application you are using to print?

- When was the last time your printer was working fine?

- Were there any changes made to your printer recently?

- May I know which devices are you using to print eg: Windows PC, Mac, or Smartphone (Android or iPhone)?

Note: Do not share any of your personal information such as serial, phone number, email ID, etc.

Take care and have a great day ahead!
