Hi, I'm Nathan.
Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review your details here.

Expert:  Nathan replied 4 months ago.

Are you seeing this on the computer, or the printer itself?

I am seeing the message on the printer
Expert:  Nathan replied 4 months ago.

Can you please look at the printer itself and tell me if any lights, error, or other indicators are showing there?

Customer: replied 4 months ago.
The on light the home light the ? and the return light plus the error message
Expert:  Nathan replied 4 months ago.

And you are sure the error is on the printer (not the computer)?
Can you recheck, as the error/code you sent is not a valid one.

Customer: replied 4 months ago.
If it is not the printer why is it on the printer? and why wont it turn off?
Expert:  Nathan replied 4 months ago.

I'm not saying that the printer is not the problem, just that the code you provided is not valid. I am asking you to recheck it as you may have some numbers/letters wrong.

Thank you for checking,

Unfortunately, the issues you are experiencing are symptomatic of an internal hardware defect, meaning a faulty power supply or logic board. This issue could be a manufacturing defect, but is also often caused by a power event (shock/surge, prolonged over/under voltage condition, etc).

This could also be the result of age related wear and tear, as a 2015 model, that type of failure wouldn’t be surprising as this machine was designed and built for only a 3 year service life at most.

There is one step you can take here, both as a possible fix, as well as a diagnostic evaluation

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

If this reset process does not work, it would unfortunately confirm an internal hardware failure.

This is something that would require repairs to correct; at that point it is time for a new printer. While it can be fixed, it is not practical to do so. You'd be in the $150 range to have the internal power supply replaced, and a logic board would run you $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 help with finding parts, finding a local repair shop, or recommending replacement options for you. Just let me know.

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

Thank you for your help. If it does not work, will be getting a new printer.

You are very welcome!

If looking for a replacement, I’d recommend any of the Epson workforce series printers. They tend to be very reliable, are easy to set up and use, have good print quality, and reasonably priced ink. Example: or

Note that these, like all consumer grade inkjet printers, are designed to be low cost and are essentially disposable after a few years, subsidized by the high cost of ink cartridges. If you wish to have a better quality and longer lasting printer, that comes with years worth of ink up front, consider the Epson ecotank models instead:

Alternately, for a more business/commercial grade product that will be rated for a 5 year life, consider a laser printer. Lasers cost more up front also, but a toner cartridge can last for thousands of pages. A black only all in one laser is around $125:

while a color model is about twice that:

If you have any other questions, just let me know. Otherwise, please take a moment to rate my service as this is the only way I am credited for my time. Hopefully I have earned 5 Stars but if not please let me know what I can do to ensure you are satisfied. I also invite you to contact me directly with any future support needs at and ask for Nathan.

Thank you, ***** ***** a nice day,
