5.3.5 Motor Control and Drivers

This printer has six motors (space motor, line feed motor, tractor motor, front and rear tractor selection gear
open/close motor, APTC motor, and ribbon motor) in a standard configuration. It also enables two
optional motors for the front and rear cut sheet feeders (the driving circuits are built in the sheet feeders) to
be mounted.
The motor controller (MB91110) controls eight motors using the motor control FPGA.
