Welcome to HP support community.


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



Run a Print Quality Diagnostic report

  1. Load plain white paper in the tray.

  2. On the printer, touch Settings, touch Tools, and then touch Print Quality Report.

If that does not print fine, check the ink cartridge vents

  1. Open the ink cartridge access door.

  2. Press the tab on the front of the ink cartridge to release it, and then pull it out of the slot.

    Remove the cartridge from the slot

  3. Examine the vent area on the top of the ink cartridge.

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

  5. Make sure the orange pull tab is completely removed.

  6. Insert the ink cartridge into its slot. Press down until it snaps into place.

  7. Repeat these steps for any other ink cartridges with defects on the report.

  8. After reinserting all the ink cartridges, run your finger along the top of the ink cartridges. If any are protruding, press down firmly until each ink cartridge snaps into place.
