Removing The Power Stacker - IBM Infoprint 6500-v05 Maintenance Manual

6. Using the rear operator panel, press the PAPER ADVANCE (down arrow) key until three or four pages feed through the
stacker throat.
a. Check the LCD on the front operator panel for faults. If there is a fault, the paper out detector is failing and needs to be
checked and cleaned.
b. If there are no faults on the LCD, load the forms in the printer and through the stacker throat. Feed enough forms into
the stacker so that they fold properly in the tray or stacker base.
7. Run a Ripple Print or All H's operator print test (page 213), and make sure that both rows of rubber paddles are rotating
inward and the pinch rollers are rotating downward.
8. Run the All E's + FF test (page 213) for ten pages. The stacker should stack and fold the paper without errors.
9. Move the elevator up approximately one inch and cover the emitter with opaque or black tape. From your laptop or the host
computer, run a multiple page print job. The elevator should start to move upward about 1/2 inch every three seconds until
it reaches its topmost position. The LCD should display 018 STACKER FULL CHECK STACKER when the elevator
reaches the top of its travel.
10. Lower the elebator by pressing ELEVATOR DOWN key. The elevator should stop at its bottom position without motor
noise. If you hear motor noise, do the "Stacker 'chatters' at upper or lower limit" procedure on page 189.
11. Set the elevator at the lowest position permitted by the amount of paper stacked in the tray. Run an operator print test and
induce a paper jam before the paper throat of the power stacker. 017 STACKER JAM CHECK STACKER should display on
the front operator panel.
12. If the stacker has not failed any test up to this point, the stacker checks out OK. If errors occurred during these checks refer
to Table 7 on page 462 and troubleshoot the appropriate symptom. When the stacker is operational, clear the error log and
place the printer in the READY state.
Stacker Motor Check
1. Power off the printer.
2. Open the rear cabinet door.
3. Unfasten the cable clamp holding the stacker operator panel cables.
4. Disconnect stacker rail cable connector P107 from J3 on the back of the stacker operator panel.
5. Disconnect stacker frame cable connector P102 from connector J4 on the back of the stacker operator panel.
6. Find pin 1 of connectors P107 and P102.
7. Check both cables for damaged pins, continuity, and shorts.
