Prograf Pro-310 not recognizing A3+ paper

smithe — Thu, 24 Jul 2025 04:57:34 GMT

My Pro-310 printer doesn’t recognize the A3+ paper. I tried to enter the dimensions manually when “A3+” didn’t work, I’ve tried both the top and rear feeds, I’ve gone in and disabled the Paper Mismatch as advised in the online instructions, and I keep getting an error code: 2115.

All my programs are up to date and I even got the Canon paper just in case something about the weight was an issue. My PS settings match the printer settings, and I’ve followed all the instructions provided by the antique-style display panel on my printer as well as instructions provided on this site… When I started this process I thought this was operator error. Now I'm not so sure...any suggestions for how to solve or circumvent this problem would be greatly appreciated.

Hello!

It's frustrating your Canon Pro-310 isn't recognizing A3+ paper, giving error 2115 despite all your efforts. This error points to a paper setting mismatch for the manual feed tray. The most crucial step is to ensure the paper size and type (e.g., A3+, Photo Paper Pro Platinum) selected on the printer's actual display panel for the manual feed tray precisely match what you've set in Photoshop and loaded physically. Also, confirm you're loading only one sheet at a time, print-side up, and check if any deeper driver settings or a printer reset might help.

Give Canon support a call.

All my settings match each other. I've even taken pix of it so that when i contact Canon support I can show them my settings match.

Thanks for answering my question. I think I am headed up to the support team, tho!!

having the same issue not recognizing A3+ paper, reinstalled driver, reboot, all the above for basic troubleshooting and cant get it to not give me the paper error that its not loaded in the manual feeder. Tried many sheets or just a few same result. Any fix to this?
