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, James.
This is a “diffuse” message which simply denotes an internal fault. That can be caused by anything from debris/obstruction (paper jam, bent/damaged rails, out of place purge assembly/wiper, or dirty/dislocated encoder strip) to an actual hardware defect (bad sensor or control board, faulty carriage drive motor/gear/belt, bad printhead/carriage pcb).
What we can try here are some cleaning and reset steps.
First, open up the printer, and check for any internal debris such as scraps of paper, paperclip or staple, etc. Check if you’re able to move the carriage manually, or if it moves on its own when lifting the lid. If it does move, you can proceed with cleaning by blowing out the Inside compartment with compressed air and checking carefully on both sides for any obstructions. Next remove all of the ink cartridges, then clean the metal electrical contacts on the back, as well as where they mate up inside the printer, using qtips and rubbing alcohol. Dry well, then reseat the cartridges. Then wipe down the encoder strip, which is a clear plastic strip running the width of the printer, that sits just slightly above and behind the carriage.
Then reset the machine:
unplug power at the wall outlet
wait 5 minutes
press and hold the power/on button for 60+ seconds
keep holding while plugging back in, and for another 60 seconds after, then release
Let me know the results, and I’ll advise further if needed.
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.
