Stacker Problems
460
a. Check the stacker limit switches (page 191).
b. Move the elevator up and down using the ELEVATOR UP and ELEVATOR DOWN keys on the rear operator panel.
While the elevator is moving, press the ELEVATOR UP or ELEVATOR DOWN key. Elevator motion should stop.
c. With the elevator at its lowest position, run the Shuttle Slow test () from the front operator panel. While the test runs,
interrupt both IR beams, one at a time, and verify that the elevator rises.
d. With the Shuttle Slow test running, verify that:
- Both paddle shafts rotate downwards towards the paper stack;
- While holding each of the idler rollers one at a time, the rest of the idler assembly continues to rotate freely;
- That the pinch rollers are rotating downwards at the pinch point;
- With the elevator at its lowest position, create a stack of four continuous forms. Press the FORM FEED key on rear
operator panel. All of the forms should pass through the pinch rollers and stack normally.
Stacker Confidence Check
1. Verify that all cables are properly connected at the back of the rear operator panel.
2. From the rear operator panel, do and observe the following:
a. Power on the printer and make sure it goes the READY state.
b. The green LED should be on.
c. Press the ON LINE key and observe the yellow LED. The yellow LED should come on when the printer is online.
d. The yellow LED should be off when the printer is offline.
e. Press the PAPER ADVANCE (down arrow) key. The printer should do a form feed every time you press this key.
f. Press and release the ELEVATOR UP key. The elevator should go up.
g. Press and release the ELEVATOR DOWN key. The elevator should go down.
3. Disable the power stacker from the configuration menu using the front operator panel. With the printer in the NOT READY
state (offline), press the ELEVATOR UP key on the rear operator panel. The elevator should move upward and
automatically stop when it reaches its highest position. (Do NOT force it up.)
4. Using the heaviest form available at the customer’s site, slide the form over the paper path and into the stacker throat. It
should be able to go through the stacker throat without having to force it. If the form cannot go through the stacker throat,
do the STACKER JAM troubleshooting procedure on page 50.
5. With the power stacker still at its highest position, enable the power stacker using the configuration menu atthe front
operator panel. Put the printer in READY state. The stacker elevator should automatically go to the lowest position
possible, depending on how much paper is in the stacker tray.
