Lower Tray Full

[C]
[B]
[A]: Lower tray full sensor (sort/shift mode)
[B]: Lower tray lift motor
[C]: Lower tray encoder sensor
[D]: Encoder disk
[E]: Lower tray full sensor (saddle-stitch mode)
[F]: Lower tray paper sensor
The sensor that is used depends on which mode the user has selected.
Normal sorting/stapling, without saddle stitching: When the bottom of the tray
actuates sensor [A], the lift motor [B] continues to rotate for a certain number of
rotations. The rotations are detected using sensor [C] and encoder disk [D]. Then
printing stops. If sensor [C] fails, the upper limit switch (lower tray) stops the motor.
This switch (not shown in the diagram) is next to the plastic foam roller at the feed-
out slot.
Saddle-stitch mode: Sensor [A] is not used. The tray is lowered until the actuator
on the side of the tray actuates sensor [E]. Then printing stops.
In both modes, when the stack is removed from the tray, sensor [F] de-actuates
and returns the lower tray to the initial position at the feed-out slot.
