The fan iscontrolled by the CPU on the DC controller PCB. Its operating conditions are as follows:1. During normal rotation, in the fixing cleaning mode (user mode), or after paper has reached the registration clutch2. During transfer roller cleaning (user mode) or after operation of the main motor1. After post-rotation, after completion of the cleaning mode, or 30 seconds after stop of the main motor2. After stop of the main motor due to opening of a door or occurrence of a jam or other failuresThe 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.F-9-2ASICCPULEDLCDKey SWImage processorPCB Control panel PCBFM1Fixing unitDownload Free Service Manual And Resetter Printer at http://printer1.blogspot.com
