Table 3. General Symptom List
Power Stacker
1. Check that the power stacker is enabled under the Printer
Control menu. (Refer to the Setup Guide.) If the power
stacker enable/disable option does not appear in the
menu, go to the next step.
2. Open the rear cabinet door. Check that the ON/OFF
indicator lamp is lit. If the ON/OFF indicator is not lit, go to
step 3. If the ON/OFF indicator is lit, press the ON LINE
key and check that the ON LINE indicator lights. If the ON
LINE indicator comes on, the stacker is detected by the
printer. If the ON LINE indicator does not come on, go to
step 4.
3. a) Power off the printer.
b) Unfasten the cable clamp holding the stacker control
panel cables.
c) Disconnect the stacker power cable from the back of the
stacker control panel. (See Figure 69, page 344.)
d) Locate pin 1 of connector P106. (See the cable
assembly drawing in Appendix A.)
e) Power on the printer.
f) At connector P106 check for +48 volts DC between pins
1 and 2 and +5 volts DC between pins 3 and 4. If the
voltages are correct, replace the stacker control panel. If
the voltages are not correct, power off the printer, remove
the paper path, and disconnect the stacker power cable
from the controller board. (See Figure 72, page 347.)
Check the continuity of the stacker power cable between
P105 and P106. If the cable fails the continuity test,
replace it. If the cable is OK, replace the controller board.
4. Power off the printer. Remove the paper path. Disconnect
stacker cables from the controller board, stacker
assembly, and the stacker control panel (see Figure 69,
page 344). 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.
5. Power on the printer. Check that the ON LINE indicator
lights on the stacker control panel. If the ON LINE indicator
does not light, replace the stacker control panel.
6. Power on the printer. Check that the ON LINE indicator
lights on the stacker control panel. If the ON LINE indicator
does not light, replace the controller board.
