Sensor
SR3 The separation sensor (SR3) does not turn on within 50
msec after the separation motor (M1) has started to rotate.
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.
U502 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.
SR3
The separation sensor (SR3) is on when separation of the
original starts.
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.
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.
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.
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.
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.
SR5 The reversal registrations sensor (SR5) does not turn on a
specific time after the reversal inlet sensor (SR4) has turned don.
SR5 The reversal registration sensor (SR5) doe not turn off a
specific time after the reversal inlet sensor (SR4) has turned off.
U505 The flapper is not switched when the reversal outlet sensor
(U505) checks the switch-over at each delivery.
SR5 The delivery sensor (SR5) does not turn off within a specific time
after the reversal delivery motor (M3) has started to rotate
counterclockwise.
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).
SR4 The reversal inlet sensor (SR5) doe not turn on a specific period
after delivery has started.
