New HP PC operating with Windows 11 and my HP Envy 7640 printe  is suddenly giving me poor print quality with horizontal streaks in documents and weird colors.

Hi @hurricanerick, Welcome to the HP Support Community! 

Your printer’s suddenly gone abstract artist on you, huh? 🎨 Streaks and weird colors definitely aren’t part of the design!

Here’s how to fix the issue:

Check Ink Levels

• Open the HP Smart app or the printer’s control panel.
• Check the ink levels and replace any cartridges that are low or empty.

Clean the Printheads

• On the printer’s control panel, go to Setup > Printer Maintenance > Clean Printhead.
• Follow the on-screen instructions. You may need to run the cleaning process multiple times.

Print a Test Page

• Print a Print Quality Diagnostic Page:
  • Go to Setup > Reports > Print Quality Report.
  • If you see gaps or streaks in the color bars, a second printhead cleaning may be needed.

Align the Printhead

• Go to Setup > Printer Maintenance > Align Printhead.
• Follow the prompts and print an alignment page.

Check for Clogged Nozzles

• If streaks persist, remove the ink cartridges and gently clean the nozzles with a lint-free cloth slightly dampened with distilled water.
• Let them dry before reinserting.

Update Printer Firmware

• Visit HP Support to check for firmware updates.
• In the HP Smart app, go to Advanced Settings > Printer Updates.

Use Genuine HP Ink

• If you’re using third-party cartridges, consider switching to genuine HP cartridges, as they work best with HP printheads.

Thank you Kuroi for your suggestions.  I have actually done all those things you mentioned, including cleaning the black cartridge with a clean cloth and distilled water.  The tri-color cartridge tested perfectly fine, but the black cartridge would not even after I cleaned it.  Thinking it was the driver because it is an older printer that was working fine with my Windows 10 HP laptop; but this ugliness started with my new HP Windows 11 laptop.  Anyway, I downloaded the HP Smart App and the "recommended" driver went through all the layers until I got a page with "Windows 11 and HP Envy 7640 are NOT supported."

I'm looking for a new printer now.  Thank you again for trying to help.
