HP 6970 Does not print black

My Officejet Pro 6978 will not print in black. The page comes out blank. The problem came on suddenly as I printed a page earlier in the day with no problem. I tried the steps from unplugging, then clean the printhead and that just comes out in blue with no black at all. I also tried the align printhead, again no black ink came on page.  Anything else I can do? I replaced the black ink cartridge even though it didn't need it. I purchased this printer in January.

@Lamb3740

 

Welcome to HP forums, I see that your printer is not printing in black.

 

Check the estimated ink levels

On the printer control panel, touch the Ink Level Indicator icon . The control panel displays estimated ink levels.

Consider replacing cartridges marked  or  when print quality becomes unacceptable.

 

If the black cartridge is good enough then, follow the below steps:

 

Make sure the black ink cartridge is properly vented and seated correctly

  1. Turn on the printer, if it is not already turned on.

  2. Open the ink cartridge access door.

    The carriage moves to the center of the printer.

    Open the cartridge access door

  3. Wait until the carriage stops moving before you continue.

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

  5. Examine the vent area above the HP logo on the top of the ink cartridge.

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

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

    3. Unclogged vent

  8. Turn the ink cartridge so that the ink cartridge contacts face downward, and then match the label color with the color dot on the carriage.

  9. Slide the ink cartridge into its slot, and then gently press the ink cartridge down until it snaps into place.

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

  11. Make sure each ink cartridge is firmly installed 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.

  12. Close the ink cartridge access door.

Same issue here, amongst many others.  None of that worked. What was the fix to this?

This did not solve the problem.  The printer still does not print in black.  All other colors print correctly.
