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, and Q515 turns ON. As a result, +24V is supplied to the
motor coil.
Stepping pulses are output from ASIC 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.
The timing chart is below.
