JAM type	Misfeed at vertical transport section (When PF-P20 or PF-P21 is installed)
JAM code	20-02
JAM detection timing	For paper fed from the tray 2/3, loop forming has not been complete before a sheet enters the registration roller because the rise timing of load to perform registration is earlier than the rise timing of load to form a loop.
–	Paper jam of a sheet of paper left at the vertical transport section results, if a sheet of paper is determined to exist at a position detected when the main power switch is turned ON, a door is opened and closed, or a misfeed or malfunction is reset.
Misfeed processing location	• Right door • Tray 2 right door • Tray 3 right door
Relevant parts	• Main motor (M1) • Tray 2 drive motor (M1/2) • Tray 3 drive motor (M1/3) • Registration clutch (CL4) • Tray 2 transport clutch (CL2/2) • Tray 3 transport clutch (CL2/3) • Registration sensor (PS9) • Tray 2 transport sensor (PS6/2) • Tray 3 transport sensor (PS6/3) • Base board (BASEB) • Tray 2 PC control board (PCCB/2) • Tray 3 PC control board (PCCB/3)
