8-1-10-1 Head Feeding Mechanism

This printer is using DC24V PM Type Stepping motor.

As shown in figure the motor section consists of the motor. Motor speed control IC, motor drive/brake circuit and motor speed interface.

When the carriage motor is driven and the carriage motor gear is moved in the direction of arrow B(forward rotation), the rotational power is conveyed to the belt drive pulley, then the belt. Next the carriage sub assembly, which is fixed to the belt, moved in the direction of arrow B.

When the carriage motor gear is rotated in the direction of arrow A (reverse rotation), the carriage sub assembly is moved in the direction of arrow A.
