CANON Error Code E03.PAPER.JAM.REAR

The E03 error indicates a paper jam specifically detected in the rear access area or duplexing unit of your Canon printer.

1. 1

   Turn off your Canon printer and unplug it from the power outlet to ensure safety.

2. 2

   Carefully open the rear access cover of the printer. This panel is usually located on the back and may have latches or clips.

3. 3

   Gently pull out any visible jammed paper. Always pull in the direction of the paper path, if possible, to avoid tearing.

4. 4

   If you have a duplexing unit, remove it (if detachable) and check underneath and inside for any small pieces of torn paper.

5. 5

   Inspect the entire rear paper path for any small scraps of paper, staples, paper clips, or other foreign objects.

6. 6

   Close the rear access cover securely, ensuring it clicks into place if applicable.

7. 7

   Plug the printer back in and turn it on. Allow it to initialize and see if the error clears.

8. 8

   Try printing a test page with fresh, good-quality paper loaded correctly in the paper tray.

9. 9

   If the error persists, try running the printer's internal cleaning cycle for paper rollers, if available in your printer's menu.

10. 10

    Consider replacing the paper you are using with a fresh ream, as old or damp paper can cause frequent jams.

If you've meticulously followed all the DIY steps, including checking for small paper scraps and foreign objects, and the E03 error continues to appear, it's time to consider professional assistance. Persistent E03 errors often indicate a deeper mechanical issue, such as a faulty paper sensor in the rear path, worn-out rollers that aren't picking up paper correctly, or a problem with the duplexing unit itself. These issues typically require specialized tools and expertise for diagnosis and repair, which are beyond standard user maintenance.
