CHAPTER 2 OPERATIONS
VII . FANS
1. Outline
The machine is equipped with a power supply fan (FM1) for cooling the switching regulator.
The fan starts to rotate when the drive signal (FANON) from the finisher controller PCB goes '0'.
While in rotation, the fan sends the FANSTP signal to the finisher controller PCB; otherwise, the
signal will go '1', causing the finisher controller PCB to assume that the fan has stopped and indicate
an error code on the copier's control panel.
Figure 2-702 shows the location of the fan and the flow of the air; Figure 2-701, on the other
hand, shows the timing at which the fan turns on.
