PAPER FEED

6.9.8 PAPER HEIGHT DETECTION

Two paper height sensors [A] and [B],
working in combination, detect the
amount of paper in the tray.
When the amount of paper decreases,
the bottom plate pressure lever [C]
moves up and the actuator [D] mounted
on the same drive shaft as the pressure
lever rotates.
The following combinations of sensor
signals are sent to the printer controller.
