Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble, Daisy.
This is not something that can be reset.
Unfortunately this error indicates a hardware problem,
specifically, it is the result of a bad printhead (or the logic board that controls it).
Since you have already replaced the head, that leaves the main logic board or the carriage pcb as the failure point.
The head (and board) is a "wear item" that fails with age/use. As this is a 2009 model printer, it is well past its 3 year service life, so this type of failure is not surprising. The printer has served well over double its designed life at this point and greatly exceeded any value that could be reasonably expected of it.
While it can be fixed, it is not worthwhile to do so. You would have to, at a minimum, replace the printhead (again), which costs about $85; if the logic board is bad you’re looking at $200-250. For $80-100 you can replace the entire machine with a brand new model, with current technology and a fresh warranty, which makes more sense than buying the new part for an older printer.
Your best recourse here is to return that new printhead, and start fresh with a new printer.
Depending how you'd like to proceed, I can advise on finding parts, finding a local repair shop, or recommending replacement options for you. Just let me know.
