This jam is detected during the time after the scanning of an original from the large original exit
side set at the scanning position until the original passes through the read sensor.
• Jam pulse setting
The setting value for the jam pulse is the equivalent number of pulses it takes for the longest
original (LD) to pass through the read sensor and proceed more 30mm.
16. 6. 3. Jams at large original exit section
(1) Original jammed not reaching the large original exit sensor (while discharging)
• Jam detection
This jam is detected during the time after an original comes to the 4th roller until it reaches the
large original exit sensor.
• Jam pulse setting
The setting value for the jam pulse is the equivalent number of pulses it takes for an original to
proceed the distance from the 4th roller to the large original exit sensor plus 30mm.

(2) Original jammed at the large original exit sensor (while discharging)
• Jam detection
This jam is detected during the time after the leading edge of an original passes the position
20mm further from the 4th roller until it passes through the large original exit sensor.
• Jam pulse setting
The setting value for the jam pulse is the equivalent number of pulses it takes for the leading edge
of an original to proceed the distance from the position 20mm further from the 4th roller to the end
of the large original exit sensor plus 60mm.
(3) Original jammed not reaching the large original exit sensor (while registering the back side)
• Jam detection
This jam is detected during the time after the back side registration or transportation to the 1st
roller starts until an original reaches the large original exit sensor.
• Jam pulse setting
The setting value for the jam pulse is the equivalent number of pulses it takes for an original to
proceed the distance from the large original exit roller to the large original exit sensor plus 60mm.
16. 6. 4. Jams at small original reverse section
(1) Original jammed not reaching the small original reverse sensor
(to the small original reverse side)
• Jam detection
This jam is detected during the time after an original reaches the intermediate transport roller until
it reaches the small original reverse sensor.
• Jam pulse setting
The setting value of the jam pulse is equivalent number of pulses it takes for an original to proceed
the distance from the intermediate transport roller to the small original reverse sensor plus 60mm.
(2) Original jammed at the small original reverse sensor (to the small original reverse side)
• Jam detection
This jam is detected during the time after the deceleration, which is set to finish at the position
20mm short of the small original reverse sensor, starts until an original passes through the small
original reverse sensor.
• Jam timer setting
The setting value for the jam timer is the time mentioned above plus necessary time for an original
to proceed 60mm.

(3) Original jammed not reaching the small original reverse sensor
(from the small original reverse side to the small original exit side)
• Jam detection
This jam is detected during the time after discharging starts at the small original reverse section
until an original reaches the small original reverse sensor.

The setting value for the jam timer is three times as much time as mentioned above.
(4) Original jammed at the small original exit sensor
(from the small original reverse side to the small original exit side)
• Jam detection
This jam is detected during the time after an original reaches the small original exit sensor until it
passes through the small original reverse sensor.
• Jam timer setting
The setting value for the jam timer is 1.5 times as much time as it takes for an LT, which is the
longest original (of all kinds of small-sized paper) when discharging small originals, to pass
through the small original reverse sensor.
16. 6. 5. Jams at small original exit section
(1) Original jammed not reaching the small original exit sensor
(from the intermediate transport section side)
• Jam detection
This jam is detected during the time after an original reaches the intermediate transport roller until
it reaches the small original exit sensor.
• Jam pulse setting
The setting value for the jam pulse is the equivalent number of pulses it takes for an original to
proceed the distance from the intermediate transport roller to the small original exit sensor plus
60mm.
(2) Original jammed at the small original exit sensor (from the intermediate transport section side)
• Jam detection
This jam is detected during the time after the deceleration, which is set to finish at the position
20mm short of the small original exit sensor, starts until an original passes through the small
original exit sensor.
• Jam timer setting
