Troubleshooting Canon Printer Support Code 1240

1. Turn Off and Unplug
For safety, turn off your printer. Unplug it from the power outlet. This prevents accidental shocks and protects your printer.
2. Find the Jam
Check these areas for jammed paper:
- Paper tray: Carefully remove the paper tray and look for any stuck sheets or obstructions.
- Rear tray (if applicable): If you use the rear tray for feeding paper, check there as well.
- Inside the printer: Open all the access panels on your printer (refer to your manual for their locations). Gently look for and remove any jammed paper.

- Check for small pieces: After removing the main jam, inspect for any torn pieces that might remain.
4. Reload the Paper
- Fan the paper: Before reloading, fan the paper stack to prevent sheets from sticking together.
- Don’t overfill: Don’t overload the paper tray. Follow the fill line indicators.
5. Restart and Test
Plug your printer back in and turn it on. Try printing a test page to see if the issue is resolved.
Preventing Paper Jams
