6.14.2 PAPER FEED ERROR DETECTION (A, B JAM)
The machine detects an error if one of these occurs:
•
The paper registration sensor and paper feed timing sensor are both on
immediately after the main switch is turned on.
•
During printing, paper upper wrapping is detected (see section 6.14.3), but after
the drum stops, the paper feed timing sensor is also on.
Delay
Paper Feed Jam
1) The registration sensor is not on at these times:
Normal paper: within 308 pulses (96.8 mm) + Retry 308 pulses.
Thick paper: 319 pulses (100.2 mm) + Retry 319 pulses.
2) When the paper feed motor starts, the paper feed start sensor is ON.
Delay
Registration Feed Jam
The paper feed timing sensor is not
on within 85 pulses (26.7 mm).
