CANON Error Code 13.21
MEDIUMCommon IssueCanon Error 13.21: Paper Jam in Fuser Delivery Area
Error 13.21 on Canon printers indicates a paper jam specifically detected in the fuser delivery area, preventing paper from exiting the printer.
Canon error code 13.21 typically signals a paper jam occurring after the paper has passed through the fuser assembly but before it reaches the output tray. The fuser is responsible for melting toner onto the paper, and this error suggests the paper successfully fused but then encountered an obstruction or issue during its final journey out of the printer. Common causes include small pieces of paper stuck from previous jams, debris like staples or paper clips, worn or damaged exit rollers, or issues with the duplexing path if the paper is attempting to print on both sides. This error is usually triggered by a sensor that fails to detect the paper at the expected time or detects it for too long, indicating it's either stalled or crumpled. While often a simple jam, persistent 13.21 errors can point to mechanical problems within the paper exit path, such as worn gears or misaligned components, which can be exacerbated by using incorrect paper types or heavily curled media.
- 1
Turn off the printer and unplug it from the power source to ensure safety before proceeding.
- 2
Open all accessible covers and trays, including the rear cover, top cover, and any side access panels, to gain full visibility of the paper path.
- 3
Carefully inspect the paper exit area, the fuser unit (if accessible without tools), and the path leading to the output tray for any visible paper fragments, crumpled sheets, or foreign objects.
- 4
Gently pull any jammed paper in the direction of the paper's normal travel. Avoid tearing the paper, as small pieces left behind can cause future jams.
- 5
Use a flashlight to thoroughly check for small, hidden pieces of paper or debris, especially around rollers and sensors.
- 6
Close all covers and trays securely. Ensure they click into place.
- 7
Plug the printer back in and turn it on. Attempt to print a test page to see if the error has cleared.
- 8
If the jam persists, try removing and reseating the fuser unit (if your model allows for user replacement) to ensure it's properly seated.
- 9
Ensure you are using paper that meets the printer's specifications for weight and type. Heavily curled or damp paper can contribute to jams.
You should consider calling a printer technician if, after performing all the DIY troubleshooting steps, the 13.21 error persists. This indicates a deeper mechanical or electronic issue that cannot be resolved with simple jam clearing. This might include worn or damaged fuser rollers, faulty paper exit sensors, issues with the duplexing unit, or internal component damage that requires specialized tools and expertise to diagnose and repair. Continued attempts to force paper through a damaged mechanism can lead to more extensive and costly repairs.
