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.
Amount of Paper
Near End
30%
70%
100%
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.
