Stacker Stacker Motor Check - Printronix P7000 Series 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 print test (page 211), 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 211) 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 STACKER FULL 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 194.
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. STACKER JAM 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 4 on page
42 and troubleshoot the appropriate symptom. When the stacker is
operational, clear the error log and place the printer online.
