Detecting Jams

Outline

The following sensors are provided to check whether paper is present and whether the
stapler is operating normally.
• Buffer Sensor (S1)
• Feed Path Sensor (S2)
• Staple HP sensor (S11)
• Staple edging sensor (S12)

Occurrence of a jam is checked (at the check timing) according to the sensor detection state
stored in the CPU on the finisher controller PCB.
When the finisher controller PCB judges that a jam has occurred, it stops feeding/delivering
paper and notifies occurrence of the jam to the host machine.
Jam type Sensor
Buffer Sensor S1 Detected when the Buffer Sensor (S1) does not detect paper
delay jam after lapse of the specified time since reception of a paper
delivery signal from the host machine.
Feed Path S2 Detected when the Feed Path Sensor (S2) does not detect
Sensor delay jam paper after lapse of the specified time since detection of paper
by the Buffer Sensor (S1).
Feed Path S2 Detected when the Feed Path Sensor (S2) does not turn off
Sensor staionary after lapse of the specified time since detection of paper by
jam the Feed Path Sensor (S2).
Buffer Sensor S1 Detected when the Buffer Sensor (S1) detects paper without
early arrival jam receiving a delivery signal from the host machine.
Or detected when the Buffer Sensor (S1) detects paper earlier
than the specified timing after reception of a delivery signal
from the host machine.
Stapler jam S11 Detected when the staple HP sensor (S11) cannot detect the
stapler again even after the specified time has lapsed since
the stapler passed through the staple HP sensor (S11) when
stapling is executed.
Or detected when the staple edging sensor (S12) cannot
detect a staple even when recovery operation is performed
ten times when staple edging is executed.
Door open jam S1/S2 Detected when the front door is opened while paper is being
fed (the Buffer Sensor (S1) or Feed Path Sensor (S2) detects
paper).
Power-on jam S1/S2 Detected when the Buffer Sensor (S1) or Feed Path Sensor
(S2) detects paper during power-on.
Error avoidance - When the controller detected the following errors during
jam feeding operation.
• Error in the paddle motor (E577)
• Error in the front alignment motor (E530)
• Error in the rear alignment motor (E537)
• Error in the tray auxiliary guide motor (E583)
• Error in the gripper motor (E575)
• Error in the stack tray shift motor (E540)
• Error in the staple motor (E531)
