JAM type	Misfeed at tray 2 feed section
JAM code	12-01
Detection timing	The leading edge of the paper does not turn ON the tray 2 vertical transport sensor (PS19) even after the lapse of a given period of time after the tray 2 starts to feed paper.
–	Tray 2 vertical transport sensor (PS19) is turned ON when the main power switch is turned ON, a door or cover is opened and closed, or a misfeed or malfunction is reset.
–	Tray 2 paper feed sensor (PS20) is turned ON when the main power switch is turned ON, a door or cover is opened and closed, or a misfeed or malfunction is reset.
–	In case paper position is detected as locating properly after main power switch is turned ON, door and cover are opened / closed or jam/trouble reset is done, it is regarded as paper jam at tray 2 feed section.
Misfeed processing location	-Right door -Tray 2
Relevant parts	-Paper feed motor (M22) -Tray 2 vertical transport motor (M23) -Tray 2 paper feed clutch (CL1) -Tray 2 vertical transport sensor (PS19) -Tray 2 paper feed sensor (PS20) -Expansion control board (EXCB) -Printer control board (PRCB)
