A Canon printer paper jam refers to a common issue where paper becomes stuck inside a Canon printer during printing. This can happen due to misaligned paper, overfilled trays, or debris inside the printer. Resolving it typically involves carefully removing the jammed paper and checking the printer's rollers and trays for obstructions to restore smooth operation.
