Thanks for posting your question on Justanswer.com, a global paid independent support site.My Name is ***** ***** I will be assisting you today. The problem you are facing is caused due to two reasons, one defective printhead or two defective logic board. Unfortunately, in both the cases, you have to send the printer for repairing. But, before that you can try the steps below and check the result. Let me know, if you need any further help otherwise please remember to give a positive rating, as that is the only way I am compensated for my time and effort.
Remove all the cartridges.
Turn off the printer and unplug.
Clean the contacts on the cartridges as well as inside the printer with cotton swab and IP alcohol.
Power on the printer.
Reseat the cartridges.
