Note that these sensors are not used unless the optional printer controller has
been installed. Then the current status can be viewed from the driver. Note that
this feature is only available for the optional paper tray units.
The two paper height sensors detect the amount of paper in the tray.
The actuator is attached to the bottom plate pressure lever.
The lift motor rotates to increase the feed pressure when the remaining paper
falls below a certain amount.
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. To counteract this, the lift motor rotates forward for a short while
after the remaining paper falls below a certain level. This increases paper
feed pressure, simulating the pressure generated by a full tray.
