Page 23: Paper Lift
DETAILED DESCRIPTIONS 10 March 2006 2.2 PAPER LIFT 2.2.1 TRAY DETECTION When a tray is set in the machine, the tray detection method used depends on the tray: • The upper tray and middle tray are detected when any one of the paper size switch signals is low. -
Page 24: Lift Sensor
10 March 2006 DETAILED DESCRIPTIONS 2.2.3 LIFT SENSOR B832D930.WMF When the lift motor turns on, the pick-up solenoid [A] activates to lower the pick-up roller [B]. When the top sheet of paper reaches the proper paper feed level, the paper pushes up the pick-up roller and the actuator [C] on the pick-up roller supporter [D] de-activates the lift sensor [E] to stop the lift motor. -

The paper size switch contains three microswitches. -
Page 26: Remaining Paper Detection
10 March 2006 DETAILED DESCRIPTIONS 2.4 REMAINING PAPER DETECTION B832D932.WMF The amount of paper remaining in the tray is detected by the three paper height photo-interrupter sensors on the left rail as the bottom plate rises. Five states, determined by the position of the actuator are possible. 1. -
Page 27: Paper End Detection
DETAILED DESCRIPTIONS 10 March 2006 2.5 PAPER END DETECTION B832D933.WMF The paper end sensor [A] detects the top sheet of the paper in the tray by monitoring the reflected light. When the paper tray runs out of paper, the paper end sensor does not receive the reflected light due to the cutout [B]. -
Page 28: Image Position Correction
10 March 2006 DETAILED DESCRIPTIONS 2.6 IMAGE POSITION CORRECTION B832D934.WMF The image position sensor [A] is located in the LCT paper path above the paper path and in front of the LCT exit rollers. (This sensor is mounted on its own control board.) The sensor is a CIS (Contact Image Sensor). -
