installed, install the input tray.
2 Turn the printer off and on to reset the printer.
ERROR CYCLE POWER: Event log message: 56.00.02
Description:
Indicates an illegal output error. For example, the multi-bin
mailbox is not installed and it was selected as the output destination, or
there are transparencies in the duplexer.
Action:
1 Open the printer and remove media from the paper path.
2 Verify that the media type is set in the printer control
panel.

7 Check the AC power supply.
8 If the problem is not rectified after the printer is turned
off and on again, find the cause of activation of the over current/overvoltage detection
circuit in the power supply. Wait more than two minutes before turning the
power back on.
9 Replace the power supply.

J703-1 (GND) on the carousel motor PCA after the printer is turned on. If the voltage
changes from 0 V to 24 V, replace fan 2.
5 Measure the voltage across connector J701-1 (+24 VB) and
J701-2 (GND) on the carousel motor PCA after the printer is turned on. If the voltage
is about 24 V, replace the carousel motor.
6 Measure the voltage across connector J641-1 (+24 VB) and
J641-4 (GND) on the main relay PCA after the printer is turned on. If the voltage
is 24 V, replace the main relay PCA.
7 Check the AC power supply.
8 If the problem is not rectified after the printer is turned
off and on again, find the cause of activation of the over current/overvoltage detection
circuit in the power supply. Wait more than two minutes before turning the
printer back on.
9 Replace the power supply.
FAN FAILURE: Event log message:57.00.03
Description:
One of the cooling fans failed.
3 = Fan 3 (FM 3)
Action:
