All operations related to carriage movement are driven by the CA motor. The CA motor
assembly consists of a motor, a timing belt, an idle pulley, and an idle pulley holder and
pulley holder spring: the motor and the idle pulley holder are mounted to the CA frame;
the belt runs between the motor and the pulley. The pulley holder spring between the
idle pulley holder and the CA frame sets belt tension. See Fig. 1.9.
