2.6.2 Detecting Jams (Saddle Stitcher Unit)

The saddle stitcher unit identifies any of the following conditions as a jam, and sends the jam signal to the host
Sensor Jam Condition
PI104 When the feed path sensor (PI104) does not
detect paper after prescribed time (distance) has
elapsed since the inlet sensor (PI103) detected
paper.
PI104 When paper does not exit the feed path sensor
(PI104) after delivering for a prescribed time
(distance) after the delivery sensor (PI104) has
detected paper.
PI118 When the escape tray path sensor (PI118) does
not detectpaper after a prescribed time (distance)
haselapsed since reception of a delivery signal
from the host machine
PI118 When paper does not exit the escape tray path
sensor (PI118)after a prescribed time (distance)
has elapsed since this sensor detected paper.
When the tray 1 or tray 2 loading position has not
been changed at reception of a delivery signal
from the host machine, or when the reception
interval of the delivery signal from the host
machine is shorter than the paper processing
time by 150 ms or more.
PI50 When the staple motor (M1111) is rotated
forward, the staple home position sensor (PI5)
does not turn back ON after a prescribed time has
elapsed after it goes OFF, and the staple home
position sensor (PI50) becomes ON within
prescribed time after the staple motor (M1111) is
rotated backward.
* Replace the stapler unit when the staple
home position sensor (PI50) becomes faulty
since it is built in the stapler unit.
PI103, When paper is detected by the inlet sensor
PI104, (PI103), the delivery path sensor (PI104), or the
PI118 escape tray path sensor (PI118) during power on.
PI102, When the front cover open/close sensor (PI102)
MSW101 or the front cover close detect switch (MSW101)
detects that the cover is opened.
