JAM typeMisfeed at tray 2 feed section
JAM code12-01
JAM detection timingThe leading edge of the paper does not turn ON the tray 2 vertical transport sensor (PS12) even after the lapse of a given period of time after the tray 2 starts to feed paper.
Paper jam of a sheet of paper left at the tray 2 feed section results, if the tray 2 vertical transport sensor (PS12) is turned ON when the main power switch is turned ON, a door is opened and closed, or a misfeed or malfunction is reset.
When the main power switch is turned ON, residual paper detection starts between each sensor. Paper jam of a sheet of paper left at the tray 2 feed section results, if the tray 2 vertical transport sensor (PS12) is turned from OFF to ON.
