7.7.2. SCAN MOTOR DRIVE CIRCUIT
1. Functions
This motor functions for main operations including FAX transmission.
This feed document paper synchronized for reading.
2. Motor operation
During motor driving, pin 25 of ASIC IC606 becomes a high level, and Q613, Q620 turns ON.
As a result, +24V is supplied to the motor coil.
Stepping pulses are output from ASIC IC606 pins, 21, 22, 23, 24, causing driver IC610 pins,
16~13todrivethemotorcoil.
The motor coil is energized sequentially in 2 phase increments, which causes a 1-step rotation.
A 1-step rotation feeds 0.065mm of document paper.
