Paper Height Detection
D331 18 SM
2.5 PAPER HEIGHT DETECTION
The amount of paper in the tray is detected by the combination of on/off signals from two
paper height sensors [A] and [B].
When the amount of paper decreases, the bottom plate pressure lever [C] moves the
actuator up.
The following combination of sensor signals is sent to the copier/printer.

When the tray contains paper of a small width, the paper feed pressure may become too
low when the thickness of the remaining stack of paper has decreased. The lift motor
rotates forward 300 ms after the sensor detects a certain amount of paper remaining in the
tray to increase paper feed pressure, simulating the pressure generated by a full tray.
