JAM code

JAM detection timing
• Base board (BASEB)
Action
13-01
The leading edge of the paper is not turned ON (unblocked) the tray 3 transport sensor (PS6/3)
even after the lapse of a given period of time after the tray 3 starts to feed paper.
13-40
For paper fed from the tray 3, the image write start signal permit continues to be disabled for a
predetermined period of time after the timing of the image write start signal output.
-
Paper jam of a sheet of paper left at the tray 3 paper feed section results, if the tray 3 transport
sensor (PS6/3) is turned ON (unblocked) when the main power switch is turned ON, a door is
opened and closed, or a misfeed or malfunction is reset.
-
Paper jam of a sheet of paper left at the tray 3 paper feed 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.
• Right door
• Tray 3
• Tray 3 drive motor (M1/3)
• Tray 3 paper feed clutch (CL1/3)
• Tray 3 transport clutch (CL2/3)
• Tray 3 transport sensor (PS6/3)
• Tray 3 PC control board (PCCB/3)
Action
20-02
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.
20-10
The leading edge of the paper is not turned OFF (blocked) the tray 2 transport sensor (PS6/2) even
after the lapse of a given period of time after the tray 2 starts to feed paper.
