Sensor Description
notation
S4 At time of separation, the separation sensor does not detect the original when it has been moved over a
specific distance (221 mm) after the start of the separation motor.
S4,S2 At time of separation, the pre-registration sensor does not detect the original when it has been moved
over a specific distance (93 mm) after the separation sensor has detected its lead edge.
S3 At time of pickup, the post-registration sensor does not detect the original when it has been moved over
a specific distance (40 mm) after the start of the reversal motor.
S2 At time of pickup, the pre-registration roller sensor detects the original when it has been moved over a
specific distance (330 mm if small; 660 mm if large) after the start of the reversal motor.
S1 At time of reversal, the reversal sensor does not detect the original when it has been moved a specific
distance (104 mm) from the platen roller.
S1 At time of reversal, the reversal sensor detects the original when it has been moved over a specific
distance (original length x 1.5 mm) after the end of arching.
PI13 At time of delivery, the delivery sensor does not detect the original when it has been moved over a
specific distance (631 mm - original length) after the start of the belt motor.
PI13,S9 At time of delivery, the manual feeder registration roller sensor detects the original when it has been
moved over a specific distance (original length + 100 mm) after the delivery sensor has gone on.
PI13,S9 At time of delivery, the delivery sensor detects the original when it has been moved over a specific
distance (100 mm) after the manual feeder registration roller sensor has gone off.
S3 At time of pre-reversal, the post-registration roller sensor does not detect the original after it has been
moved over a specific distance (50 mm) from the start of the reversal motor.
S1,S3 At time of pre-reversal, the reversal sensor does not detect the original when it has been moved over a
specific distance (100 mm) after the post-registration roller sensor has gone on.
