7.4.5. STEPPING MOTOR DRIVE CIRCUIT (TX)
1. Function
The stepping motor works for transmission.
2. Motor
During motor driving, pin 131 of ASIC IC501 becomes a high level, and Q507, Q504 turns ON. As a result, +24V is supplied
to the motor coil.
Stepping pulses are output from ASIC IC501 pins, 125, 128~130, causing driver IC510 pins, 16~13 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
document paper.
The timing chart is below.
The motor suspends while it is in the receive mode (about 70~80 msec), pin 131 of ASIC IC501 becomes a low level and Q507
turns OFF. Then Q504 also turns OFF, and instead of +24 V, +5 V is supplied through D504 so that the motor is held in place.
When the system is in the stand-by mode, all of the motor drive transistors turn OFF. Consequently, the motor current stops.
