Abstract
A dot matrix printer having a plurality of hammers forming in part a hammerbank, with a motor for driving the hammerbank, and a controller for releasing the hammers for printing on a print media. A counterbalance is mechanically linked to the hammerbank for balancing it during movement. Lands and grooves are connected for rotation with the motor. A sensor sends pulses corresponding to the lands and grooves for controlling the hammerbank movement. The hammerbank is linked to the position of the lands and grooves as mechanically connected to the motor.
