OVERALL MECHANICAL INFORMATION
Name
lift motor off.
Detects when the last sheet feeds from the 6th
tray.
Detects the paper when it arrives at the 6th paper
feed roller and checks for misfeeds.
4th from the bottom of the 6th tray, detects stack
height: 100%
5th from the bottom of the 6th tray, detects stack
height: 75%
6th from the bottom of the 6th tray, detects stack
height: 50%
4th from the bottom of the 6th tray, detects stack
height: 25% and signals near-end.
Detects the length of the paper in the 6th tray
(used in combination with the paper width
sensors).
1 of a set of 3 sensors that detect the width of the
paper in the 6th tray.

1 of a set of 3 sensors that detect the width of the
paper in the 6th tray.
Detects the leading and trailing edges of the paper
in the paper path near the 6th tray. Checks the
timing of the feed and signals a jam if the paper is
late or lags at this location.
Detects jams in the paper path where the
transport motor feeds the paper from the 6th tray.
Detects jams at the exit of the LCT unit.
Mounted on the CRB (CIS Relay Board), this
contact image sensor detects the side-to-side
edges of the paper in the paper path. The
machine uses this information to correct the
position of the image when the lasers fire.
