Welcome to the HP support community.

I understand that you are getting print quality issues and alignment issues.

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.

Align the printer

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

2. Swipe up on the display, and then touch Printer Maintenance.

3. Touch Align Cartridges, and then touch Continue.

   The printer prints an alignment page.
