Controlling the Feed Motor
0002-9874
The following is a diagram of the circuit used to control the feed motor (M2). The feed
motor (M2) is a 4-phase stepping motor, and the circuit has the following functions:
- turning on/off the motor
- changing the rotation direction of the motor
- changing the rotation speed of the motor
F-2-39
The CPU (IC9) on the ADF driver PCB receives data (command) from the host machine
on printing mode (magnification, operation mode, timing); in response, it generates drive
pulses to drive the feed motor (M2). The feed motor (M2) is a stepping motor, and its
direction and speed of rotation are changed by changing the order of drive pulses (A, A*,
B, B*).
