Stacker media bin
The stacker media bin goes up and down to an appropriate position according to the volume of media fed from
the compiler unit assembly so as to properly stack media to “full stack”.
Operation
The stacker media bin moves to an appropriate position according to the volume of media fed from the compiler
unit assembly. The sensor (stacker bin level 1) and the sensor (stacker bin level 2) detect the height of media in
the stacker media bin, and the sensor (stacker bin level encoder) determines the volume of media in the tray.
When media or the stacker media bin comes between the light emitter and the photo-receiver of the sensor
(stacker bin level 1) and sensor (stacker bin level 2), the emitted light is blocked, and the sensors turn “H”. The
height of media or the stacker media bin is detected based on the levels of these sensors.
This sensor information is used to control the elevator motor. The motor is activated to move the stacker media
bin while the sensor (stacker bin level) turns from the light blocking state to the light receiving state.
The sensor (stacker bin no media) is turned On or Off by the actuator attached to the carriage assembly right on
the rear side of the finisher. In case the stacker media bin abnormally goes up above the sensor (stacker bin no
media), the sensor (stacker bin upper limit) is installed above the sensor (stacker bin no media) for protection
against abnormal operation.
If an operator removes media from the stacker media bin during printing, it is detected by the sensor (stacker bin
level 2), and the ejection of media to the stacker media bin is inhibited. Then the elevator motor is activated to
move the stacker media bin to the sensor (stacker bin level 1) sensing area. Thus, the ejection of media to the
stacker media bin is restored.
If an operator removes media from the stacker media bin while printing is stopped, it is detected by the sensor
(stacker bin level 2). After three seconds have passed, the elevator motor is activated to move the stacker media
bin to the sensor (stacker bin level 1) sensing area. Thus, the ejection of media to the stacker media bin is
restored.
