Welcome to HP support community.

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

If copy quality is not fine, follow the below steps:

Make sure that the ink cartridges are properly vented

1. Grasp the handles on either side of the ink cartridge access door, and then raise the door until it locks into place.

   The carriage moves to the access area.

2. Press the tab on the front of the ink cartridge inward to release it, and then pull up on the ink cartridge to remove it from the slot.

   • If the error message mentions a specific ink cartridge, locate that ink cartridge, remove it from the carriage, and then continue with the next step.

   • If the error message does not mention a specific ink cartridge, remove all the ink cartridges, one at a time, and then continue with the next step.

3. Examine the vent area on each ink cartridge, above the HP logo on the top of the ink cartridge.

4. If the ink cartridge still has the orange pull-tab attached, pull to remove it.

5. If the vent is clogged, use a straight pin to gently remove excess adhesive from the vent.

7. With the nozzle and the contacts facing down, push the ink cartridge into its slot. Press down on the ink cartridge until it clicks into place. Make sure that the color icon on the ink cartridge label matches the color icon on the slot.

   NOTE: 

   Make sure that each ink cartridge is installed in the correct slot. Match the shape of the icon and the color of the ink cartridge with the slot that has the same shaped icon and color.

8. Repeat these steps to inspect the vents on each of the ink cartridges.

9. Make sure that each ink cartridge is firmly in place in its slot. Run your finger along the top of the ink cartridges to feel for any that are protruding, and if any are, press down firmly until each ink cartridge snaps into place.

10. Close the ink cartridge access door.

11. Try the print job again.

Clean the printhead automatically

1. Load plain, white paper into the paper tray.

2. On the printer control panel, press the down arrow  to select Settings, and then press OK.

3. Press the down arrow  to select Tools, and then press OK.

4. Press the down arrow  to select Clean Printhead, and then press OK.

   The printer cleans the printhead, and then prints a test page.

Let me know how it goes.
