New HP902XL black ink cartridge prints imperfectly

[DougOlson]

I installed a new HP 902XL black cartridge in my OfficeJet Pro 6978 printer this afternoon. The black ink cartridge prints randomly, sketchily, and not the complete whole document. I have "run" a 'Print Quality Diagnostics' page, 'Align Printheads' page, 'Clean Printheads' page, 'Clean Printer' page, 'Print Diagnostic Information' page, and 'Print Status Report' page and the new HP 902 XL black cartridge still does not print all of the document. What do I do?

Welcome to the HP support community.

Make sure the ink cartridges are 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.

   

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.

8. 1. 

      Clogged vent

   2. With a straight pin, gently remove excess adhesive from the vent

   3. Unclogged vent

9. 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.

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

    

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

12. 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.

13. Close the ink cartridge access door.

Good afternoon, Sandytechy20:

Thank you, very much, for writing to me, yesterday, January 10, 2020, with a possible solution to 'why' the new HP902XL black ink cartridge is not printing in my HP OfficeJet Pro 6978 printer. I very carefully tried your solution and the black ink cartridge still did not print. Do you have any other solutions on how to correct this problem? Thank you!!

Yours truly,

Doug Olson

P.S. I tried to insert into this e-mail three (3) PDF files showing the three (3) pages that did not print the black ink. I was not successful doing this.

D.O.
