This machine has a fan on the rear side to discharge the hot air around the fixing unit and cool the laser scanner unit and electric elements on PCBs. The fan is
controlled by the CPU on the DC controller PCB. Its operating conditions are as follows:
<Startup conditions>
1. During normal rotation, in the fixing cleaning mode (user mode), or after paper has reached the registration clutch
2. During transfer roller cleaning (user mode) or after operation of the main motor
<Stop conditions>
1. After post-rotation, after completion of the cleaning mode, or 30 seconds after stop of the main motor
2. After stop of the main motor due to opening of a door or occurrence of a jam or other failures
The CPU on the DC controller CPU outputs a Fan Drive signal (FANON = 'H') to turn the fan.
The CPU judges that a fan failure has occurred if it detects a Fan Lock Detection signal (FANLOCK = 'H') during fan rotation.
