CHAPTER 2 BASIC OPERATION
The sensors and conditions used to identify jams are as follows:
Jam Code Sensor Condition
Separation delay 0002 SR3 The separation sensor (SR3) does not turn on within 50
msec after the separation motor (M1) has started to rotate.
Pickup delay 0003 U502 The pre-registration sensor (U502) does not turn on within 1 sec
after the original has left the separation sensor (SR3) in the
case of a small-size original or a point near the separation
sensor in the case of a large-size original.
Pickup stationary 0005 U502
0006 SR3
The pre-registration sensor (U502) does not turn off when the
feed motor has rotated for 500 msec after the original was made
to arch at the registration roller.
Reversal outlet
delay
0011 U505 The reversal outlet sensor (U505) does not turn on a specific
time after the trailing edge of the original has moved past the
right edge of the belt registration roller.
Reversal outlet sta-
tionary
0012 U505 The reversal outlet sensor (U505) does not turn on when the
delivery motor has rotated for 500 msec after the reversal regist-
ration sensor (SR5) detected the trailing edge of the original.
Duplexing pre-
registration sensor
delay
0023 U502 The pre-registration sensor (U502) does not turn on a specific
time after the double-sided original has been moved to the pick-
up unit side from the copyboard glass after it was turned over.
Delivery inlet delay 0041 SR4 The reversal inlet sensor (SR4) does not turn on when the feed
motor (M2) has been rotated for an equivalent of 10 mm after
the original is picked up in the case of a small-size original or
from a point 51 mm of the reversal inlet sensor (SR4) in the case
of a large-size/double-sided original.
Delivery stationary 0042 SR4 The reversal inlet sensor (SR5) does not turn off a specific time
after the leading edge of the original has reached the reversal re-
gistration roller nip in the case of a small-size original or after the
leading edge of the original has reached the reversal outlet
sensor (U505) in the case of a large-size/double-sided original.
Reversal registra-
tion delay
0043 SR5 The reversal registrations sensor (SR5) does not turn on a
specific time after the reversal inlet sensor (SR4) has turned don.
Reversal flapper
fault
0045 U505 The flapper is not switched when the reversal outlet sensor
(U505) checks the switch-over at each delivery.
Delivery sensor
delay (small-size)
0046 SR5 The delivery sensor (SR5) does not turn off within a specific time
after the reversal delivery motor (M3) has started to rotate
counterclockwise.
Delivery sensor
stationary
(small-size)
0047 SR5 The delivery sensor (SR5) does not turn off when the trailing
edge of the original has been fed 50 mm after it has moved past
the delivery sensor (SR5).
Delivery sensor
delay (large-size,
double-sided)
0048 SR4 The reversal inlet sensor (SR5) doe not turn on a specific period
after delivery has started.
Reversal registra-
tion stationary
0044 SR5 The reversal registration sensor (SR5) doe not turn off a
specific time after the reversal inlet sensor (SR4) has turned off.
The separation sensor (SR3) is on when separation of the
original starts.
