16. 6. Jams
16. 6. 1. Jams at feeding section
(1) Original jammed not reaching the original length sensor
• Jam detection
This jam is detected during the time after the feed motor begins to rotate forward to start
separation until an original reaches the original length sensor.
• Jam timer setting
The setting value for the jam timer is three times as much time as it takes to transport an original
from the pickup position (where the empty sensor detects the original) to the original length
sensor.
(2) Original jammed not reaching the registration sensor
• Jam detection
This jam is detected during the time after an original comes to the position 10mm short of the
registration sensor (24.6mm further from the original length sensor) until it reaches the registration
sensor.
• Jam timer setting
The setting value for the jam timer is three times as much time as it takes to transport an original
from the middle position between the original length sensor and registration sensor to the
registration sensor.
16. 6. 2. Jams at transporting section
(1) Original jammed at the original length sensor
• Jam detection
This jam is detected during time after the feed motor starts to rotate in reverse so that the
registration roller starts to transport an original to the read roller until the trailing edge of the
original passes through the original length 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 original length sensor and proceed more 60mm.
(2) Original jammed at the registration sensor
• Jam detection
This jam is detected during the time after the original passes through the original length sensor
until it passes through the registration 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 original length sensor to the registration sensor plus 60mm.
