Line Feed
The drive circuit is made up of transistors
Q8, Q9, Q10, and Q11. Four drive signals
from the gate array are processed in this
circuit. Higher voltage and current are
added to the phase control signals to turn on
the line feed motor. The signals are sent to
the line feed motor and the ribbon motor
through CN1.
Ribbon Motor Drivers
This circuit is made up of transistors Q3,
Q4, Q5, Q6 and Q7. When turned on, the line
feed motor signals from the gate array are
supplied with more current in the drive
circuit and sent out to the motor. The
common return line is on Q7, which is
turned on for each phase signal sent to the
motor. These signals are sent through CN5.
