4.4 Paper Jam Detection
The printer has a registration sensor and a paper eject sensor at the paper outlet to detect
whether the printed paper has been fed correctly. A paper jam is detected by whether the paper
is present at the sensor at the check periods programmed in the engine CPU memory. If the
engine CPU detects a paper jam, the main motor, paper feed motor and scanner motor is turned
off immediately and the jam status is transmitted to the video controller circuit.
A paper jam is detected in any of following conditions:
1)
Paper exists at the paper ejection sensor or the registration sensor when power is
switched on. (JAM REAR or JAM INSIDE)
2)
Paper has not reached the registration sensor within a specified time (JAM TRAYS).
3)
Printed paper has not passed through the registration sensor within a specified time (JAM
INSIDE (1) ).
4)
Printed paper has not reached the paper ejection sensor within a specified time (JAM
INSIDE (2) ).
5)
Printed paper has not passed through the paper ejection sensor within a specified time
(JAM REAR).
