System and method for optically detecting media feeding malfunctions in an image forming apparatus

A system and method for optically detecting media feeding malfunctions in an image forming apparatus captures images of a surface of a sheet of media as image signals to detect positional changes of the sheet of media. The detected positional changes are used to determine that a media feeding malfun...

Zusammenfassung:A system and method for optically detecting media feeding malfunctions in an image forming apparatus captures images of a surface of a sheet of media as image signals to detect positional changes of the sheet of media. The detected positional changes are used to determine that a media feeding malfunction has occurred when the positional changes satisfy a predefined condition.
