PAPER HEIGHT DETECTION

2.4 PAPER HEIGHT DETECTION
The amount of paper in the tray is
detected by the combination of two
paper height sensors [A] and [B].
When the amount of paper decreases,
the bottom plate pressure lever [C]
moves up and the actuator [D], which
is mounted on the same drive shaft as
the pressure lever, rotates.
The following combination of sensor
signals is sent to the copier.
