Multi-purpose tray pick-up unit fan FM5 failure

CHAPTER 4

Action: Disconnect connector J216 on the DC controller PCB. Turn the power switch ON and measure the voltage between connector J216-1 (FAN2D) and J216-3 (GND) on the DC controller PCB. If the voltage changes from 0 to more than 18V, replace the power supply fan.

3.The DC controller PCB is defective. Action: Replace the DC controller PCB.

VI-9. "13.3 ERROR FAM 3 CALL FOR SERVICE" Fixing unit/scanner fan (FM1) failure

<Possible causes>

1. The FM1 drive signal line connector is loose.

Action: Reconnect connector J208 on the DC controller PCB.

2. The fixing unit/scanner fan is defective.

Action: Disconnect connector J208 on the DC controller PCB. Turn the power switch ON and measure the voltage between connector J208-1 (FAN1D) and J208-3 (GND) on the DC controller PCB. If the voltage changes from 0 to more than 18V, replace the fixing unit/scanner fan.

3.The DC controller PCB is defective. Action: Replace the DC controller PCB.

VI-10. "13.4 ERROR FAM 4 CALL FOR SERVICE" Fixing unit fan (FM4) failure

<Possible causes>

1. The FM4 drive signal line connector is loose.

Action: Reconnect connector J225 on the DC controller PCB and connectors J25 and J26.

2. The fixing unit fan is defective.

Action: Disconnect connector J225 on the DC controller PCB. Turn the power switch ON and measure the voltage between connector J225-1 (FAN4D) and J225-3 (GND) on the DC controller PCB. If the voltage changes from 0 to more than 18V, replace the fixing unit fan.

3.The DC controller PCB is defective. Action: Replace the DC controller PCB.
