These are the motors that drive the rollers of the stacker:
- [1] Entrance motor. Drives the entrance rollers and other transport rollers that feed the paper straight through the stacker to the transport motor.
- [2] Shift tray exit motor. Drives the rollers that feed paper from the shift tray junction gate onto the shift tray.
- [3] Proof tray exit motor. Drives the rollers that feed paper up from the proof tray junction gate to the proof tray on top of the stacker.
- [4] Transport motor. Drives the rollers that feed paper out of the stacker from the straight-through paper path.
This is a cross-sectional view of the paper feed path and the motors.
The entrance motor [1] drives not only the entrance roller but several other feed rollers as well.
The shift tray junction gate [2] is opened by the shift tray junction gate motor [3]. When the junction gate is opened, paper is guided to the shift tray. The shift tray exit motor [4] drives the shift rollers that feed the paper onto the shift tray. When the shift tray junction gate is closed, paper passes over to the proof tray junction gate.
The proof tray junction gate [5] is closed by the proof junction gate motor [6]. When the gate is closed, paper passes over the junction gate into the paper path for the proof tray [7] above. The proof tray exit motor [8] drives the rollers in the paper path to the proof tray. When the proof tray junction gate is open, the paper passes below the junction gate towards the stacker exit.
Once the paper has passed both junction gates, the paper will be fed by the rollers driven by the transport motor [9] until it exits the stacker at [10].
