PCBs
No. Name
Description
PCB1
Main Control Board
Controls the operation of all motors and sensors in
the LCT unit.
PCB2
Image Position Sensor Board
Operates the CIS sensor (performs waveform
correction) the LCT. The CRB (CIS Relay Board) and
CIS sensor perform side-to-side image correction.
The CRB and CIS are a single unit. The CRB is not a
separate board.
Sensors
No. Name
Description
S1
4th Lift Sensor
Detects when the paper in the 4th tray is at the
correct height for paper feed and switches the 4th
lift motor off.
S2
4th Paper End Sensor
Detects when the last sheet feeds from the 4th
tray.
S3
4th Paper Feed Sensor
Detects the paper when it arrives at the 4th paper
feed roller and checks for misfeeds.
S4
4th Paper Height Sensor 1
4th from the bottom of the 4th tray, detects stack
height: 100%
S5
4th Paper Height Sensor 2
5th from the bottom of the 4th tray, detects stack
height: 75%
S6
4th Paper Height Sensor 3
6th from the bottom of the 4th tray, detects stack
height: 50%
S7
4th Paper Height Sensor 4
4th from the bottom of the 4th tray, detects stack
height: 25% and signals near-end.
S8
4th Paper Length Sensor (B834)
Detects the length of the paper in the 4th tray
(used in combination with the paper width
sensors).
S9
4th Paper Width Sensor 1 (B834)
1 of a set of 3 sensors that detect the width of the
