Chapter 3
The presence of a jam, on the other hand, is checked by the finisher controller PCB, running a check at such
times as programmed in advance.
When the finisher controller PCB finds a jam, it will cause the stitcher controller PCB to suspend the ongoing
transport/delivery operation and communicate the presence of a jam to the host machine.

Sensor Description
PS3 The inlet sensor (PS3) does not detect paper within a specific period
of time (distance) after the delivery signal from the host machine
has been received.
PS3 The paper does not leave the inlet sensor (PS3) within a specific
period of time after it has detected paper.
PS4 The shift unit sensor (PS4) does not detect paper within a specific
period of time (distance) after the inlet sensor (PS3) has detected
paper.
PS4 The paper does not leave the shift unit sensor (PS4) within a specific
period of time (distance) after the inlet sensor (PS3) has detected
paper.
UN13 The buffer path 1 sensor (UN13) does not detect paper within a
specific period of time (distance) after the shift unit sensor (PS4)
has detected paper.
UN13 The paper does not leave the buffer path 2 sensor (UN14) within a
specific period of time (distance) after the shift unit sensor (PS4)
has detected paper.
UN14 The buffer path 2 sensor (UN14) does not detect paper within a
specific period of time (distance) after the shift unit sensor (PS4)
has detected paper.
UN14 The paper does not leave the buffer path 2 sensor (UN14) within a
specific period of time (distance) after the shift unit sensor (PS4)
has detected paper.
PS5 The upper delivery sensor (PS5) does not detect paper within a
specific period of time (distance) after the buffer path 2 sensor
(UN14) has detected paper.
PS5 The paper does not leave the upper delivery sensor (PS5) within a
specific period of time (distance) after the buffer path 2 sensor
(UN14) has detected paper.
PS6 The lower delivery sensor (PS6) does not detect paper within a
specific period of time after the buffer path 2 sensor (UN14) has
detected paper.
PS6 The paper does not leave the lower delivery sensor (PS6) within a
specific period of time (distance) after the buffer path 2 sensor
(UN14) has detected paper.
The lower path sensor (UN24) does not detect paper within a
specific period of time (distance) after the buffer path 2 sensor
(UN14) has detected paper.
UN24 The paper does not leave the lower path sensor (UN24) within a
specific period of time (distance) after the buffer path 2 sensor
(UN14) has detected paper.
Paper exists within the transport path at power-on.
Paper exists in the path during initial rotation of the host machine. 1721
MSW1 The front cover switch (MSW1) has identified the front cover as
being open during machine operation.
