Stacker Tray
The stacker tray is an output tray on the finisher LX that is used to store compiled sets in a
stack. The stacker tray lowers in steps to accommodate up to 200 sets.
The stacker tray is raised and lowered by a system of gears and belts. The gears and belts are
driven by the stacker elevator motor through a rack gear. Refer to

Elevation System
The position of the stacker tray is controlled by an encoder and sensor.
The encoder has a number of apertures cut into it and is connected directly to the main stacker
tray drive gear via a shaft.
As the stacker tray drive gear rotates to lower or raise the stacker tray, the encoder also
rotates. The rotation of the encoder is monitored by the encoder wheel sensor which is an opti-
cal sensor that reflects light onto the encoder. Refer to
