Chapter 5 Troubleshooting Other Symptoms
Power / IML Failures
No power, and the
operator panel is blank,
and the card cage fan is
not running
1. Check that the AC power outlet has power. Restore AC power
as required.
2. Unplug the printer AC power cord from the printer (leave it
plugged into the power outlet) and check for AC power at the
printer end of the cord. If there is no power through the AC
power cord, replace it. Plug the AC power cord into the printer
and power outlet.
3. Remove the paper guide assembly or pedestal top cover. Verify
that the AC-in power cable and the AC power input cables are
connected to the on/off switch/circuit breaker. (See Figure 46,
page 262 or Figure 53, page 280.) Connect the AC-in power
supply cable and AC power input cables to the on/off switch-
circuit breaker. Make sure all ground connections are clean and
tight.
4. Check that AC-in power cable connector P1 is connected to J1
on the power supply board.
5. Check that power supply cable connector P101 is connected to
J101 on the CMX controller board.
6. Check all cable connections on the CMX controller board.
Reseat all cables.
7. If the printer has the coax/twinax expansion board, make sure
the 60-pin expansion adapter is correctly seated in the CMX
controller board and the coax/twinax expansion board.
8. Disconnect AC-in power supply cable connector P1. Set the
circuit breaker to 1 (on). Measure AC voltage at pins 1 and 2 of
connector P1. If no voltage, replace the circuit breaker. If there is
voltage, replace the power supply board.
