Motors | |
|---|---|
Entrance Motor | Drives the entrance rollers that feed each sheet of paper as it enters the stacker. |
Shift Tray JG Motor | Opens the shift junction gate that directs paper to the shift tray. Paper goes past this junction gate to the proof tray or stacker exit when it is closed. |
Transport Motor | Drives the transport rollers that feed paper through the finisher between the entrance and the exit. |
Shift Exit Motor | Drives the shift exit rollers that output paper to the shift tray. |
Shift Motor | Moves the shift roller set (drive roller and idle roller) to the front and back. For every other document set, the shift roller will take each sheet of paper and move it to the front so every other stack is staggered. |
Proof Tray Exit Motor | Drives the proof tray exit roller that outputs each sheet of paper to the proof tray on top of the stacker. |
Proof Tray JG Motor | Opens the shift junction gate that directs the paper to the proof tray on top of the stacker. When this gate is closed, paper goes past this gate and goes to the stacker exit. |
Main Jogger Front Fence Motor | Moves the front jogger fence of the main jogger unit that aligns the front edge of the paper on the shift tray (near the front corner of the trailing edge). |
Main Jogger Rear Fence Motor | Moves the rear jogger fence of the main jogger unit that aligns the rear edge of the paper on the shift tray (near the rear corner of the trailing edge). |
Main Jogger Fence Retraction Motor | Raises both the rear and front jogger fences of the main jogger unit after each set is output to the shift tray and aligned. The fences are raised to position them for the next shifted set. |
Cooling Fan Motor for Paper Transport Motors | Cools the entrance motor, proof tray exit motor, and transport motor. |
LE Stopper Motor | Moves the leading edge stopper to the leading edge of the paper on the shift tray and stops. The leading edge of each sheet of paper is aligned against this stationary stopper. This aligns the stack in the direction of paper feed. |
Sub Jogger Motor | Operates the front and back fences of the sub jogger. The sub jogger is used to align either the front or rear edge of the stack near the front or rear corner at the LE stopper. This motor controls the movement of both the front and rear fence with a single belt. (The front and rear fence of the main jogger unit have independent motors and drive belts.) |
Tray Lift Motor | Raises and lowers the shift tray mounted on the roll-away cart. |
Paper Cooling Fan Motor 1 | These fans cool the area directly below the stacker entrance where paper enters the stacker and the shift tray.
|
Paper Cooling Fan Motor 2 | |
Paper Cooling Fan Motor 3 | |
| Cooling Fan for Entrance Motor | Cools the entrance motor. |
| Shutter Motor | Switches the shutters for the shift tray exit fans on/off. |
| Shift Tray Exit Fan | When thin or coated paper is used, this fan assists in preventing the paper from getting buckled while the paper stacks up on the shift tray. |
Sensors | |
|---|---|
Entrance Sensor | Detects each sheet of paper as it enters the stacker. Also signals a jam if the paper fails to arrive or leave within the prescribed time. |
Shift Tray Exit Sensor | Detects each sheet of paper as it enters the shift tray. Also signals a jam if the paper fails to arrive or leave within the prescribed time. |
Proof Tray Exit Sensor | Detects each sheet of paper as it is output to the proof tray. Also signals a jam if the paper fails to arrive or leave within the prescribed time. |
Proof Tray Full Sensor | When this photo-sensor detects the top of the stack in the proof tray, it signals that the proof tray is full and stops the stacking operation. |
Paper Height Sensor | Detects the height of the paper stack on the shift tray. The readings of this sensor are used to keep the tray at its optimum height for paper stacking. |
Shift Tray JG HP Sensor | Detects the shift tray junction gate when it reaches its home position and switches off the shift tray JG motor. |
Proof Tray JG HP Sensor | Detects the proof tray junction gate when it reaches its home position and switches off the proof tray JG motor. |
Shift HP Sensor | Detects the home position of the shift rollers and switches off the shift motor. |
Front Fence HP Sensor | Detects the home position of the front fence of the main jogger unit and switches off the front fence jogger motor. |
Rear Fence HP Sensor | Detects the home position of the rear fence of the main jogger unit and switches off the rear fence jogger motor. |
Jogger Fence Retraction HP Sensor | Detects the home position of the front and rear fences after they have been lowered by the main jogger fence retraction motor and switches off the retraction motor. |
Shift Tray Paper Sensor | Detects the presence or absence of paper on the shift tray. |
Tray Guard Sensor 1 | Switches off the stacker if the top of the stack pushes up the front or back plate and actuates the sensor. This stops stacker output (the straight-through and proof paper paths can still be used.) |
Tray Guard Sensor 2 | |
Exit Sensor | Detects paper as it exits to the finisher downstream. |
Transport Sensor | Monitors the passage of each sheet of paper in the feed path between the entrance and exit of the stacker. |
LE Stopper HP Sensor | Detects the leading edge stopper when it reaches its home position and switches off the LE stopper motor |
Sub Jogger HP Sensor | Detects the sub jogger when it reaches its home position and switches off the sub jogger motor. |
Tray Full Sensor 1: 25% | Detects when the shift tray is 25% full. |
Tray Full Sensor 2: 50% | Detects when the shift tray is 50% full. |
Tray Full Sensor 3: 75% | Detects when the shift tray is 75% full. |
Tray Full Sensor 4: 100% | Detects when the shift tray is 100% full. Signals tray full and shuts down the stacker. |
Tray Low Limit Sensor | Detects the low limit of the shift tray and signals that the tray must be removed. |
| Shutter Home Position Sensor | Detects whether the shift tray exit fan shutter is open or closed. |
Boards | |
|---|---|
Main Board | Performs overall control of the stacker. |
PSU | Steps down power source voltage to 24V power supply. |
Operation Panel PCB | Controls the buttons used for manual operation of the stacker tray, and contains the LEDs that indicate the status of the stacker. |
Solenoid | |
|---|---|
Front Door Lock SOL | Keeps the front door of the stacker locked so it cannot be opened while the stacker is operating. |
Switches | |
|---|---|
Top Door SW | Detects when the top door is open. While the top door is open, the power supply to the proof tray and straight-through paper path remains off. |
Front Door SW | Detects when the front door is opened. While the front door is open, the power supply to the tray lift motor and the stacker drive system remains off. |
Tray High Limit SW | A micro-switch that detects the high limit for shift tray operation and cuts power to the tray lift motor to shut it off. |
Tray Low Limit SW | Detects the lower limit for shift tray operation and cuts power to the tray lift motor to shut it off. |
Roll Away Cart Set SW | Detects when the tray cart is in the stacker. If the tray cart is not set inside the stacker, the power supply to the tray lift motor and the stacker drive system remains off. |
Breaker Switch | Shuts down the operation of the stacker in the event of a power surge. |
