3.7 Detecting Jams

3.7.1 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 (UN24)
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.

Sensor Jam description
PS3 The Inlet Sensor (PS3) doesn't detect the paper within the
specified time (distance) after the delivery signal reception sent
from connection machine.
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
PS4 Shift Unit Sensor (PS4) doesn't detect the paper within the
specified time (distance) after Inlet Sensor (PS3) detects the
paper and do the feeding.
PS4 The paper doesn't come out from Shift Unit Sensor (PS4) within
the specified time (distance) after Inlet Sensor (PS3) detects the
paper and do the feeding.
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.
UN13 The paper doesn't come out from Buffer Path 1 Sensor (UN13)
within the specified time (distance) after Shift Unit Sensor (PS4)
detects the paper and do the feeding.
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.
