HP Smart Tank 750 Black Ink Tube Empty Unable To Print Black

[JOE20208]

Hi all!

I recently got an old smart tank 750 from a friend and everything but the black ink works! The black ink tube is completely empty and the ink levels are full. I’ve tried cleaning the print head 3-5 times per HP’s instructions but nothing has worked. The other colours are fine and the ink can flow through the tubes from the ink tank to the ink head but only black cannot. Please help!!!

Hi @JOE20208,

Welcome to the HP Support Community.

Thank you for posting your query, I will be glad to help you.

I see that you are facing an issue with printing in black on your printer.

A) Please follow the steps below to perform a power drain.

 1) Unplug the power cord from the printer & wall.

2) Press and hold the power button down for 15 seconds and release the power button, wait for about 30 seconds.

3) Plug the power cord back into the printer and wall, ensure the printer is plugged into the wall & not into a surge protector.

4) Unplug the power cord > Wait for 30 seconds > Plug the power cord back in > Power on the printer

B) Kindly refer to the steps on this link to update the printer firmware and let me know if that resolves the issue.

C) Refer to the steps on this link to further troubleshoot.

D) If the issue still persists, refer to the steps on this link to restore factory defaults and let me know if that resolves the issue.

I hope this helps.

Take care and have a good day
