Clear Canon Support Code 2110 — paper size mismatch on tray, cassette paper info & driver settings

Technician

Hey! We’ll get rid of that Canon Support Code 2110 that won’t clear.
This error is Canon’s “paper size/type mismatch” warning — the printer thinks the paper loaded in the cassette or front tray doesn’t match what your computer, phone, or the printer’s own settings say.
To target the fix, tell me: which Canon model (PIXMA TS/TR/MG/G/MAXIFY/iX/etc.) do you have, which tray you’re using (rear/front/cassette 1/2), and are you printing from Windows, macOS, iPhone/iPad (AirPrint), Android, or directly copying on the panel?

Customer

It’s a Canon PIXMA. The display shows Support Code 2110 every time. I load A4 plain paper in the cassette, but it keeps saying the paper size doesn’t match, even when I tap “OK”. The 2110 error won’t clear and I’m stuck in a loop.

Technician

Got it — that’s the classic 2110 paper settings mismatch case.
On Canon inkjet models, Support Code 2110 appears when:

• The paper size or media type in the printer driver (or app) doesn’t match the cassette/front tray paper information stored on the printer, or
• You switched between A4 / Letter / 4×6 / 5×7, glossy vs plain, borderless vs normal, without updating one side.

Our plan is to:

1. Check what size/media the printer thinks is loaded in the cassette.
2. Match that with your Windows/macOS/AirPrint driver settings.
3. Show how to use “Print with the loaded paper” and “Replace the paper” correctly.
4. Optionally adjust or disable Canon’s “detect paper setting mismatch” so 2110 stops popping up unnecessarily.

Customer

Where do I see what the printer thinks is loaded? I just put A4 in the cassette and hit print from my PC. Windows says A4, but I still get the 2110 size mismatch.

Technician

Perfect, let’s align the settings — this alone clears most Support Code 2110 loops.

Step 1 — Check cassette paper information on the printer
On the Canon’s touch screen or LCD:

• Go to Paper settings / Feed settings / Cassette settings.
• Find the entry for Cassette / Front tray (or Cassette 1 / Cassette 2).
• Confirm it’s set to Size: A4, Media type: Plain paper (or whatever you physically loaded).

If it shows Letter, Photo Paper, or different size, update it to match the real stack. The 2110 code fires anytime the internal cassette paper info conflicts with the job coming from Windows, macOS, or your phone.

Customer

The printer had Letter set for the cassette. I changed it to A4, but 2110 still pops up when I try to print from Word.

Technician

Great catch — now we match the driver side.

Step 2 — Match Windows/macOS driver to cassette info
From your PC:

• Open the Print dialog for the Canon printer.
• Click Preferences / Properties (Windows) or Print Settings (macOS).
• Set:
  • Paper Size: A4 (or the exact size you set on the printer).
  • Media Type: Plain Paper (or same photo paper as registered).
  • Paper Source: the correct tray (Cassette, Rear tray, Auto select).

If the document is set to US Letter or Borderless while the printer expects A4 plain, Canon will throw Support Code 2110 again. After syncing these three (size, type, tray), try printing one test page.

Customer

I matched A4/plain on both, but I still see prompts: print with loaded paper / replace paper / cancel. If I choose the wrong thing, 2110 comes back. What should I pick so it stops looping?

Technician

That prompt is Canon’s misprint prevention feature doing its job.

When Support Code 2110 appears:

• Print with the loaded paper: tells the printer “I know what’s in the tray, just use it.” Use this only if the paper in the tray is correct for your job.
• Replace the paper and print: use if your document size (e.g. Letter, 4×6) is right, but the tray has A4; swap paper to match, then confirm.
• Cancel: use if you want to correct settings in the print dialog instead.

After you’ve synchronized the driver and cassette settings, choosing the logically correct option once should stop the 2110 loop. If it still repeats every time, there’s usually one setting (Letter vs A4, borderless, media type, wrong tray) still out of sync — we can pinpoint it in chat if needed.

Customer

What about printing from my iPhone/iPad? I select the Canon from AirPrint and still get the Support Code 2110 on the printer.

Technician

Good question — AirPrint and Canon PRINT also rely on the printer’s tray info.

For iPhone/iPad/Android:

• On the printer, make sure the cassette/front tray is set to the size you actually use most (A4 or Letter).
• In the print dialog on your phone, confirm Paper Size matches that default.
• If 2110 appears, choose Print with the loaded paper when you know the size is correct.

If mobile apps keep sending Letter while you use A4 (or vice versa), the printer will keep warning you with Support Code 2110 paper size mismatch until they match.

Customer

Is there a way to just stop Canon from nagging me with 2110? I understand the risk, I just want the printer to use what’s loaded.

Technician

Yes — many Canon models let you reduce or disable the Detect paper setting mismatch feature.

Typical path on PIXMA/MAXIFY/GX:

• Menu / Setup → Feed settings → Detect paper setting mismatch.
• Set it to “Disable” or equivalent.

After that, the printer won’t show Support Code 2110 every time there’s a mismatch; it will just print on the loaded paper. Only use this if you’re okay with possible cropping or layout differences (e.g., Letter job on A4 paper). If you’d like, we can help you pick safe defaults for your region and media so you avoid surprises.

Customer

What if 2110 still appears even though I matched everything and tried disabling the mismatch detection?

Technician

If you’ve:

• Set cassette/front tray info correctly (A4 vs Letter, plain vs photo),
• Matched driver/mobile app Paper Size, Media Type and Paper Source,
• Chosen the correct option on the 2110 prompt, and/or disabled mismatch detection,

but Support Code 2110 still appears on every job, then:

• There may be a firmware bug or corrupted driver profile — reinstalling the Canon driver/queue often helps.
• On some models, incorrect regional defaults (US vs EU size) keep resetting; we can walk through fixing that.
• Rarely, a faulty tray sensor reports wrong paper info, making 2110 constant until serviced.

That’s the moment where a quick live session saves a lot of time. Hit Start Chat, tell us your exact Canon model and OS, and we’ll map the right settings with you.

Customer

After syncing cassette info with A4, adjusting the driver, and choosing “Print with the loaded paper”, the Support Code 2110 finally stopped. Thanks for the detailed walkthrough.

Technician

Summary: To fix a Canon Support Code 2110 paper size mismatch that won’t clear:

• Set cassette/front tray paper size & media type to match what’s actually loaded.
• Match your Windows/macOS/AirPrint settings (size, media, tray) to those values.
• On the 2110 prompt, choose the correct action once — “Print with loaded paper” or “Replace paper”.
• Optionally adjust Detect paper setting mismatch if the warning is too aggressive.

Done right, that stops the endless 2110 loop and gets your Canon printing normally. If something still doesn’t add up, open the chat and we’ll tune it one-on-one.

Quick answer: working fix for Canon Support Code 2110

Accepted fix when your Canon shows Support Code 2110 (paper size mismatch) on every job: update cassette/front tray paper info to the real size and media, match the printer driver or AirPrint settings, then confirm with “Print with loaded paper” or “Replace paper and print”. Once all three match, the 2110 error loop stops.

FAQ

Step-by-step: clear Canon Support Code 2110

1. On the printer, open Paper/Feed/Cassette settings and set the correct paper size and media for each tray.
2. On Windows/macOS, open the Canon printer preferences and match Paper Size, Media Type, and Paper Source to those tray settings.
3. Send a test print. When the 2110 screen appears, choose “Print with loaded paper” if everything matches, or “Replace paper” and adjust.
4. If warnings are too frequent and you understand the risk, adjust Detect paper setting mismatch in Feed settings.
5. Still stuck? Reinstall the printer driver/queue and repeat the alignment for a clean profile.

Note for Windows, macOS & mobile users

1. The 2110 code is generated by the printer, but your OS/app choices can trigger it if they send the wrong size.
2. On macOS and iOS, check default region and paper size; on Windows, review the printer’s default settings and app-level presets.
