16.6 Jams

16.6.1

Jams at feeding section

1) Original jammed not reaching the original length detection sensor (S63) : E711
- Jam detection
This jam is detected during the time after the document feed motor (M37) begins to rotate for-
ward to start separation until an original reaches the original length detection sensor (S63).
- 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 original empty sensor (S60) detects the original) to the origi-
nal length detection sensor (S63).
2) Original jammed not reaching the original registration sensor (S55) : E712
- Jam detection
This jam is detected during the time after an original comes to the position 10 mm short of the
original registration sensor (S55) (24.6mm further from the original length detection sensor
(S63)) until it reaches the original registration sensor (S55).
- 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 detection sensor (S63) and original registra-
tion sensor (S55) to the registration sensor.
3) Time-out of lifting tray up : E715
- Detection range
This jam is detected during the time after the lifting tray starts to be lifted until the lifting tray upper
limit sensor (S59) detects.
- Jam pulse setting
The setting value for the jam pulse is the motor driving pulse 1.5 times as mush as the normal
pulse when the lifting tray moves from the lower to upper limit.
4) Time-out of lifting tray down : E716
- Detection range
This jam is detected during the time after the lifting tray starts to be lowered until the lifting tray
upper limit sensor (S62) detects.
- Jam pulse setting
The setting value for the jam pulse is the motor driving pulse 1.5 times as mush as the normal
pulse when the lifting tray moves from the upper to lower limit.

Jams at transporting section

1) Original jammed at the original length detection sensor (S63) : E713
- Jam detection
This jam is detected during time after the document feed motor (M37) 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 detection sensor (S63).
- 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 detection sensor (S63) and proceed more 60
mm.
