Troubleshooting Other Symptoms
Stacker does not stack
properly 1. Check for and remove obstructions preventing elevator
movement.
2. Check for misaligned stacker rails. Adjust the stacker rails
if they are not vertical and parallel.
3. Power on the printer. Operate the power stacker. (Refer to
the
User’s Manual .) While the stacker is operating, check
that:
a) all motors are operating
b) the paddles are rotating
c) the elevator moves smoothly and without obstruction
d) the timing belts are undamaged and the belt pulleys are
not slipping
e) the extension springs are attached and undamaged (not
bent or stretched)
f) the drive rollers are not damaged
g) the constant force springs are tightly mounted and
undamaged
Tighten pulley setscrews and/or replace damaged
components as necessary.
4. Check the stacker limit switches. (See page 121.) If the
limit switches are OK, go to the next step.
5. Check the stacker motors. (See page 122.) If the stacker
motors are OK, go to the next step.
6. Remove the paper path. Disconnect stacker cables from
the controller board, stacker assembly, and the stacker
control panel (see Figure 74, page 368). Check cables for
cuts, breaks, or damaged pins. Check continuity of cables.
(See Appendix A.) Replace any cable that is damaged or
fails continuity test. Reconnect all stacker cables to the
controller board, stacker, and stacker control panel.

Stacker elevator moves by
itself 1. Power off the printer. Inspect all stacker LEDs for dust,
chaff, or dirt. (See Figure 100 through Figure 102,
page 396 through page 400.) Clean the stacker LEDs and
the sight tubes in the LED mounts.
2. Power on the printer. If the stacker elevator moves by
itself, replace the stacker LEDs. (See Figure 100 through
Figure 102, page 396 through page 400.)
