HP Officejet pro 6968 black ink not printing

[jcmiller]

Hi, 

I changed the black ink cartilage on my HP Officejet Pro 6968 to a new, genuine HP ink. It will now no longer print in black ink.  The display shows the cartilage is full. I have gone through the three step process of cleaning the ink head several times. I disconnected the printer while it was on, I took the ink out, aligned printer heads and cleaned printer.  HELP.

Welcome to 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.
