A method for determining accuracy of an actual position of a plurality of independent motors in a printing press is provided. The method includes commanding each of the plurality of motors in the printing press via a controller to move a desired initial position, comparing an actual position of each motor to the desired initial position of each motor, determining if the actual position of each motor is within a predetermined tolerance of the desired initial position, and resetting any motor outside the predetermined tolerance to be within the predetermined tolerance. A printing press is also provided. The printing press includes a plurality of printing press components and a plurality of motors. Each motor drives at least one of the printing press components and each of the motors has a desired initial position. The printing press also includes a position detector for determining an actual position of the motor with respect to the desired initial position of the motor.
