Purchased a 5510 about 5 months ago. Was working fine, now says... "Incompatible Printhead, The Printhead installed is not intended for use in this printer, or is damaged" Refer to printer documentation.
So, it's obviously the correct printhead, but there is NOTHING in the "documentation" about it".
I have taken the full inks out and put back in. I have looked to see if I can possibly take out the print head, but don't know how, and there is NO documetation. This is making me ANGRY. Brand new printer, barely used, and it's all messed up.
Kids are going back to school, homework will be started up again soon... need this working.
Thanks for any help!
