6.4.5. STEPPING MOTOR DRIVE CIRCUIT
1. Function
The stepping motor works for both transmission and reception.
2. Motor
During motor driving, pin 163 of ASIC IC501 becomes a high level, driver pin 12 of IC506 becomes a low level, and Q519 turns
on. As a result, +24V is supplied to the motor coil.
Stepping pulses are output from gate array IC501 pins, 157, 160~162, causing driver IC506 pins, 15~12 to drive the motor coil.
The motor coil is energized sequentially in 2 phase increments, which causes a 1-step rotation. A 1-step rotation feeds 0.13 mm
of recording paper or document paper.
