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.

Are you using genuine/oem canon inks, or generic/refilled cartridges?

Customer: replied 1 year ago.
genuine

Are you sure it is a 1414 code, and not 1401?

Expert:  Nathan replied 1 year ago.

Initially,

There are a few possible causes of this issue, including a bad cartridge, internal debris/contamination, or a hardware failure (bad printhead, bad logic board, faulty sensor, etc).

What we can try are some cleaning and reset steps.

First 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 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.

Thank you for checking.

Unfortunately the persistence of the 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 2013 model printer, it is at/past its 3 year service life, so this type of failure is not surprising.

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 $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.

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

Note:

I am an independent technician and I've spent my personal time, unpaid, in a good faith effort to assist with the question for which you solicited my services. I am only paid 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 positive 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.
