Hi, I'm Sadique. Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP
This error indicates an error with your printhead.
How old is this printer?
As of first step we will try cleaning the printhead. We will remove the printhead from the printer and then soak it in hot water for about 10 minutes. We have to clean the printhead in hot water such that no ink residue is left in it.
I'll give you a manual which will help you to remove the printhead.

I was wondering if you have any updates related to the printer.
