Canon Printer Error Code 2900: How to Fix It

Q: What does Canon error code 2900 mean?

Canon error code 2900 means the scanner lamp inside your Canon printer is failing to warm up or initialize correctly. The scanner lamp needs to reach a specific light output level before a scan or copy job can start, and this error appears when that process takes too long or fails entirely.

Q: Can I still print even when error 2900 is showing?

In many cases, yes — Canon error 2900 is specifically related to the scanner function, so standard printing from your computer may still work. However, copy jobs and scanning will be unavailable until the error is resolved, and on some Canon models the error may block all operations.

Q: How do I reset a Canon printer to fix error 2900?

To reset most Canon printers, press and hold the Stop/Reset button for 5 seconds while the printer is powered on. On models with a touchscreen menu, go to Device Settings, then Reset Settings, and select Reset All. After the reset, allow the printer to fully restart and test the scanner again.

Q: How long does the Canon scanner lamp take to warm up normally?

Under normal conditions, a Canon scanner lamp warms up within a few seconds — typically 3 to 10 seconds — before a scan begins. If the lamp is taking noticeably longer or never completes the warm-up, error 2900 will be triggered. Cold ambient room temperatures can sometimes slow warm-up slightly, but should not cause a full error.

Q: Is it worth repairing a Canon printer with error 2900 or should I replace it?

If your Canon printer is relatively new or a higher-end model, repairing the scanner lamp assembly is usually worth the cost. However, for entry-level or older Canon PIXMA printers, repair costs from a service technician may approach or exceed the cost of a new printer. Compare the estimated repair quote against current prices for a comparable replacement model before committing to professional service.

Abstract

Canon printer error code 2900 appears when the scanner lamp inside your Canon all-in-one printer or copier is taking too long to warm up or has failed to initialize properly during a scan or copy job. This typically means the lamp isn't reaching the correct temperature or brightness level needed to scan documents accurately. While this is a medium-severity issue, it is often resolvable at home through a series of resets and checks before considering professional repair.
