ABSTRACT:
A serial printer comprises a carriage, a print member rotatably mounted to the carriage, drive means coupled to the print member for rotating the print member in a desired direction and at a desired speed, and control apparatus coupled to the drive means for generating a control signal to control the direction and speed of rotation of the print member. The control apparatus comprises means coupled to the print member for generating a first signal indicative of the rotational movement of the print member, means responsive to a second signal indicative of a command to position the print wheel at a predetermined reference rotational position for applying a predetermined control signal to the drive means to rotate the print member in a predetermined direction and at a predetermined speed, means operatively associated with the print member for generating a third signal each time a predetermined portion of the print member is rotated past a predetermined reference location, means coupled to the means for generating a first signal and to the means for generating a third signal for comparing the first signal with a predetermined third signal representative of a predetermined number of rotations of the print wheel portion past the predetermined reference location, and means coupled to the means for comparing and responsive to the first and predetermined third signals bearing a first relationship for disabling the means for applying in order to stop the print member at the predetermined reference rotational position and responsive to the first and predetermined third signals bearing a second relationship for enabling the means for applying to continue to apply the predetermined control signal to the drive means in order to continue to rotate the print member in the predetermined direction and at the predetermined speed.
