Cyan color will not print.

[gclovis]

Printer is HP Office Jet Pro 6978  All-in-One

Product Number TOF29A

Cyan color will not print.  I have done the 3-pass "Clean Printhead " cycle at least 5 times, waiting at least 30 minutes between cycles.  No improvement.  I have replaced the cartridge with a NEW HP 902XL cartridge.  All cartridges are HP manufacture.  Black and other colors are all working.  Is there anything else to try?

Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help,

I understand that your Cyan ink cartridge is not printing, If you have already performed the steps from the document Black or Color Ink Not Printing: https://support.hp.com/in-en/document/c01997899 and the issue persists, it could be a hardware failure.
