Error code SCAN-ERROR on the Canon Canon imageCLASS MF453dw 40 ppm Wireless Duplex Mono Laser All-in-One Printer means: Scanner Error — Scan/Copy Function Failure. The scanning unit has encountered an error preventing scanning and copying functions. The scanner motor may have failed, the scanner carriage may be stuck, or a communication error occurred between the scanner and the main board.
