12.5.3 Toner supply motor
The toner supply motor is provided to supply toner for the process unit.
The toner supply motor is driven by transistor (IC5), and its circuit is structured as follows.
The motor winding is connected to the +24V at its (+) side and to the collector of IC5 at its (-) side.
- When TSMON signal (Toner supply motor drive signal) of the I/O port GA-1 (IC7) becomes “H” level -
• IC5 is turned on
→
The +24V power supply supplies current to IC5 via the motor winding
→
the motor rotates
- When TSMON signal becomes “L” level -
• IC5 is turned off
→
The current which was flowing in the motor winding flows via the route of diode.
→
It decreases at the rate of the time constant determined by the inductance and resistance of the
winding.
→
the motor stops.
