Welcome to the HP support community.

I understand that you are getting print quality issues, I am glad to assist you.

Did you make a copy and check if that works fine?

Meanwhile:-

Print a Print Quality Diagnostic page

1. On the control panel, swipe down to open the Dashboard, and then touch the Setupicon.

2. Swipe up on the display, touch Reports, and then touch Print Quality Report.

If that does not print fine, follow these steps to fix the issue.

Manually clean the area around the ink nozzles

1. Gather the following materials:

   • A clean, lint-free cloth or a clean, dry cotton swab

   • Distilled or bottled water

        CAUTION: 

     Do not use tap water because it might contain contaminants that can damage the printhead.

2. Open the ink cartridge access door.

   

3. Wait until the printer is idle and silent before you continue.

4. Lightly press down on the ink cartridge to release it, and then pull the ink cartridge out of its slot.

   

      CAUTION: 

   Do not remove both ink cartridges at the same time. Remove and then clean each ink cartridge one at a time. Do not leave an ink cartridge outside the printer for more than 30 minutes.

5. Hold the ink cartridge by its sides.

   

6. Lightly dampen a clean, lint-free cloth or swab with bottled or distilled water.

7. Clean the face and edges around the ink nozzle with the cloth or swab.

      CAUTION: 

   Do not clean the ink nozzle plate.

   

   1. Nozzle plate - Do not clean

   2. Area surrounding ink nozzle - Do clean

   3. Ink cartridge contacts - Do not clean

8. Wait 10 minutes for the cleaned area to dry before you continue.

9. Hold the ink cartridge by its sides with the contacts toward the printer, insert the ink cartridge into its slot, and then gently push the ink cartridge until it snaps into place.

   

10. Repeat these steps to clean around the nozzles on the other ink cartridge.

11. Close the ink cartridge access door.

No change after cleaning the ink cartridges. I noticed however that now, suddenly, HP Support is referring to my printer, scanner, copier, as a "scan only " device.

@cdtsr

This is an all in one printer

You can Scan, Copy and print using this printer.

As you have tried all possible troubleshooting steps and the issue still persists.

This seems to be a hardware issue.

I am sending you a private message with the steps to talk to HP support.

Please check the mailbox icon at the top-right corner of this screen.

I hope this helps resolve this issue completely,

Cheers.
