Detecting Jams

Jam inspection in Finisher

To detect whether there is paper or not, or whether the paper can properly be fed or not, the
followings are the detection sensor for paper.
• Inlet Sensor (PS3).
• Shift Unit Sensor (PS4).
• Upper Delivery Sensor (PS5).
• Lower Delivery Sensor (PS6).
• Buffer Path 1 Sensor (UN13)
• Buffer Path 2 Sensor (UN14).
• Lower Path Sensor (UN22)

Whether jam is occurred or not, determined by whether there is paper or not in the sensor
area by the time of timing check that memorized in advance by Finisher Controller PCB.
When Finisher Controller PCB detected jam, it will break feeding/delivery movement through
Stitcher Controller PCB. And at the same time inform the connection machines about the jam
occurrence.
Jam type Sensor
Inlet sensor delay PS3 The Inlet Sensor (PS3) doesn't detect the paper
within the specified time (distance) after the
delivery signal reception sent from connection
machine.
Inlet sensor stationary PS3 The paper doesn't come out from Inlet Sensor
(PS3) within the specified time (distance) after
Inlet Sensor (PS3) detects the paper and do the
feeding
Shift Unit Trailing Edge Sensor PS4 Shift Unit Sensor (PS4) doesn't detect the paper
delay within the specified time (distance) after Inlet
Sensor (PS3) detects the paper and do the
feeding.
Shift Unit Trailing Edge Sensor PS4 The paper doesn't come out from Shift Unit
stationary Sensor (PS4) within the specified time (distance)
after Inlet Sensor (PS3) detects the paper and do
the feeding.
Buffer Path 1 Sensor delay UN13 Buffer Path 1 Sensor (UN13) doesn't detect the
paper within the specified time (distance) after
Shift Unit Sensor (PS4) detects the paper and do
the feeding.
Buffer Path 1 Sensor UN13 The paper doesn't come out from Buffer Path 1
Stationary Sensor (UN13) within the specified time (distance)
after Shift Unit Sensor (PS4) detects the paper
and do the feeding.
Buffer Path 2 Sensor delay UN14 Buffer Path 2 Sensor (UN14) doesn't detect the
paper within the specified time (distance) after
Shift Unit Sensor (PS4) detects the paper and do
the feeding.
Buffer Path 2 Sensor UN14 The paper doesn't come out from Buffer Path 2
Stationary Sensor (UN14) within the specified time (distance)
after Shift Unit Sensor (PS4) detects the paper
and do the feeding.
Upper Delivery Sensor Delay PS5 Upper Delivery Sensor (PS5) doesn't detect the
paper within the specified time (distance) after
Buffer Path Sensor (UN14) detects the paper and
do the feeding.
Upper Delivery Sensor PS5 The paper doesn't come out from Upper Delivery
Stationary Sensor (PS5) within the specified time (distance)
after Buffer Path 2 Sensor (UN14) detects the
paper and do the feeding
