Table 41. Numbered printer messages (continued) 57.1 FAN FAILURE Event log message : 57.00.01 Description: One of the cooling fans failed or is obstructed. Action: Caution: Turn the printer off and do not operate the printer in this condition or it can be seriously damaged. 1 = Fan 1 (FM 1) 2 Reconnect connectors J702 and J706 on the carousel motor PCA, and connector J220 on the controller board. 1 Turn the printer off and on to reset it. 3 Reconnect connector J701 on the carousel motor PCA, connectors J648 and J641 on the main relay PCA, and connector J102 on the DC power supply.
4 Measure the voltage across J702-3 (FAN1ON) and J701-2 (GND) on the carousel motor PCA after the printer is turned on. If the voltage changes from 0 V to 24 V, replace fan 1. 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 not 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 overcurrent/overvoltage detection circuit in the power supply. Wait more than two minutes before turning the power back on. 9 Replace the power supply. 380 Chapter 7 - Troubleshooting EN
