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.

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.
VI-11. "13.5 ERROR FAM 5 CALL FOR SERVICE"
Multi-purpose tray pick-up unit fan (FM5) failure
<Possible causes>
1. The FM5 drive signal line connector is loose.
Action: Reconnect connector J229 on the DC controller PCB and connectors J34 and J35.
2. The multi-purpose tray pick-up unit fan is defective.
Action: Disconnect connector J229 on the DC controller PCB. Turn the power switch ON
and measure the voltage between connector J229-1 (FAN5D) and J229-3 (GND) on
the DC controller PCB. If the voltage changes from 0 to more than 18V, replace the
multi-purpose tray pick-up unit fan.
3. The DC controller PCB is defective.
