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).
