The detection sensor and detection timing, and displayed code are indicated as follows.
Jam type Sensor Detection timing Displayed code
EntryStart time-out jam -
EntryStart OFF is not detected even when the specified time has lapsed since EntryStartAck ON was replied.
2FC0
EjectStartAck time-out jam -
EjectStartAck ON is not detected even when the specified time has lapsed since EjectStart ON was reported.
EjectStartAck OFF is not detected even when the specified time has lapsed since EjectStart OFF was reported.
2FC1
Upper tray empty jam S9
An attempt is made to feed paper from the upper tray when no paper is loaded in the upper tray.
2FC2
Lower tray empty jam
S12
An attempt is made to feed paper from the lower tray when no paper is loaded in the lower tray.
2FC3
Cover open jam - The front cover is opened during inserter operation or the inserter top cover is opened during inserter operation. 2300
Power-on jam
-
Paper is detected in the unit at power-on or start of mechanism initialization.
2400
-
Paper is detected in the unit during the multi-rotation of driving mechanism such as motors, rollers, etc., for initialization.
Error prevention jam -
A jam is caused without causing an error when a problem is detected.
2C01
Emergency stop jam - The inserter stops operating upon reception of an emergency stop signal. 2FC4
Entrance sensor delay jam S20
The entrance sensor does not detect paper even when the specified time has lapsed since a paper handover request signal was
received.
20E0
Entrance sensor 2 delay jam S21
Delivery sensor 2 does not detect paper (in the horizontal paper feed mode) even when the specified time has lapsed since the
entrance sensor detected paper, or delivery sensor 2 does not detect paper even when the specified time has lapsed since paper was
inserted from the inserter.
20E2
Registration sensor jam
S3,S7 The registration sensor corresponding to the paper feed tray does not detect paper even when the specified time has lapsed since
paper fed from the inserter started.
20E4
Middle feed sensor delay jam S8
The middle feed sensor does not detect paper even when the specified time has lapsed since paper feed to the reversal unit standby
position started.
20E5
Reverse entrance sensor delay jam S18
The reverse entrance sensor does not detect paper even when the specified time has lapsed since the middle feed sensor detected
paper.
20E6
Reverse sensor delay jam S17
The reverse sensor does not detect paper even when the specified time has lapsed since the reverse entrance sensor detected paper (in
the reverse insertion mode), or the reverse sensor does not detect paper even when the specified time has lapsed since paper feed to
the reversal unit standby position started after switchback.
20E7
Reverse timing sensor delay jam S16
The reverse timing sensor does not detect paper even when the specified time has lapsed since the reverse entrance sensor detected
paper (in the straight insertion mode), or the reverse timing sensor does not detect paper even when the specified time has lapsed
since the reverse sensor detected paper (in the reverse insertion mode).
20E8
Entrance sensor stationary jam S20
Paper does not pass by the entrance sensor even when the specified time has lapsed since the entrance sensor detected paper.
21E0
Delivery sensor 2 stationary jam S21
Paper does not pass by the delivery sensor 2 even when the specified time has lapsed since the delivery sensor 2 detected paper.
21E2
Registration sensor stationary jam
S3,S7 Paper does not pass the registration sensor corresponding to the paper feed tray even when the specified time has lapsed since paper
feed to the reversal unit standy position started.
21E4
Middle feed sensor stationary jam S8
Paper does not pass by the middle feed sensor even when the specified time has lapsed since paper passed by the registration
sensor corresponding to the paper feed tray.
21E5
Reverse entrance sensor stationary
jam
S18
Paper does not pass by the reverse entrance sensor even when the specified time has lapsed since paper passed by the middle feed
sensor.
21E6
Reverse sensor stationary jam S17
Paper does not pass by the reverse sensor even when the specified time has lapsed since the reverse sensor detected paper (in the
reverse insertion mode), or paper does not pass by the reverse sensor even when the specified time has lapsed since the reverse
sensor detected paper at the start of paper feed to the reversal unit standby position after switchback.
21E7
Reverse timing sensor stationary jam S16
Paper does not pass by the reverse timing sensor even when the specified time has lased since paper insertion started.
