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.

Expert:  Nathan replied 9 months ago.

Unfortunately this error indicates a hardware problem,

specifically, it is the result of a bad printhead (or the logic board that controls it).

The head is a "wear item" that fails with age/use. As this is a 2010 model printer, it is well past its 3 year service life, so this type of failure is not surprising.

At this point the printer is at double its designed maximum lifespan and has greatly exceeded any value that could be reasonable expected of it.

There is one step you can take here, to clean and reset the system, but it is very unlikely to help. 99.9% of the time, this does come down to a hardware fault.

While it can be fixed, it is not worthwhile to do so. You would have to, at a minimum, replace the printhead, which costs about $150; 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.

Depending how you'd like to proceed, I can advise on the cleaning/reset steps if you wish to try, help with finding parts, finding a local repair shop, or recommending replacement options for you. Just let me know.

Best regards, ***** ***** for the news,

Nathan

Please note:

I am an independent technician and I've spent my personal time, unpaid, in an effort to assist with the question for which you solicited my services. This site works on the honor system, and to that end, I have prioritized working with you ahead of other paying customers.

Although you’ve already paid your fee to the site, I am only compensated for my efforts when customers such as yourself leave positive feedback for my work. Again I apologize there is not a better outcome here, though this is really beyond either of our control. I do hope you’ll consider leaving a 5 star rating for me, rather than “shoot the messenger”, so that I may get credit for my time spent in good faith to answer your question accurately. Rating 1 or 2, or not rating at all, does not produce a refund, it only penalizes me for trying to help.
