Controlling the Delivery Reversal Motor (M3)
0002-9898
The following is a diagram of the circuit used to control the delivery reversal motor (M3).
The delivery reversal motor (M3) is a 4-phase stepping motor, and the circuit has the
following functions:
- turning off/on the motor
- controlling the rotation direction of the motor
- controlling the rotation speed of the motor
F-2-35
The CPU (IC4) on the ADF driver PCB receives data (command) from the host machine
on print mode (magnification, operation mode, timing); in response, it generates drive
pulses to drive the delivery reversal motor (M3). The delivery reversal motor (M3) is a
stepping motor, and the direction and speed of rotation are changed by changing the order
and frequency of drive pulses (A, A*, B, B*).
