Printer won't print black ink

HP Recommended
Photosmart 6520

I have completed print quality diagnostics and clean printer head many times and still won't print black ink.  On print quality diagnostic, no black shows up on the black "bar" but color does.  Alignment is good.  Help please!

Welcome to HP support community.

 

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.

    1.

  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.

  9. Print another Print Quality Diagnostic report.
