E805 0000 Fan failure
only one in this copier>
The fan is faulty. -
Check the fan connector.
- Replace the fan.
- Replace the DC controller PCB.


Switching between full-speed rotation and half-speed rotation is controlled as described below.
1) Full-speed control
When the CPU on the DC controller outputs a fan full speed signal (FAN_FULL), the fan drive voltage switching circuit supplies a +24 V fan drive voltage to turn
the heat exhaust fan at the full speed.
2) Half-speed control
When the CPU on the engine controller outputs a fan half speed signal (FAN_HALF), the fan drive voltage switching circuit supplies a +16 V fan drive voltage to
turn the heat exhaust fan at the half speed.

E805-0000 (Main body fan error)
When the cooling fan of the main body starts, the fan lock detection signal (FAN_LOCK) has been held at the "H" level for longer than the prescribed time.

also check for low-voltage power supply
