FAN CONTROL
This unit is equipped with fan to prevent the developing device from rising in temperature while printing.
The air is inhaled from the left side of the unit.
The fan rotates at high speed (typ. 4800 rpm) while printing (controlling the developing device). After printing is finished, it
rotates at low speed (typ. 2400) rpm when the temperature of the unit goes up over a fixed one or depending on the number
of printed papers (frequency).
While the fan is rotating at high speed, the voltage of 24 V is supplied to the fan, however, while rotating at low speed, the
supply voltage is decreased to 12V.
Each signal wave is as follows:
1. High-speed rotation (typ. 4800 rpm)
2. Low-speed rotation (typ. 2400 rpm)
During low-speed rotation, the rotation detection does not function.
