My Canon printer's scanner is not working, showing an error. What are potential causes?

If your Canon printer's scanner function is showing an error, it could be a driver issue, a connection problem specific to the scanner component, or an internal hardware malfunction. Ensure the scanner unit is properly powered and that the necessary scanner drivers and software are installed and up-to-date on your computer. Check for any physical obstructions in the scanner bed or lid. If it's an all-in-one printer, ensure the printer itself is functioning correctly, as sometimes scanner issues are linked to overall printer communication problems.
