A control system for controlling the movement of a cutting device (74) mounted on a carriage (52) in a printer (10) between a home position to a record media cut position. The carriage (52) has photosensing means (80) secured thereto which is operably associated with a first reflecting member (82) at the home position of the carriage (52) and with a second reflecting member (84) at the record media cut position of the carriage (52). The second reflecting member (84) is operably associated with the photosensing means (80) for partial cut or for full cut of record media by the cutting device (74). The movement of the carriage (52) is controlled by the output of the photosensing means (80) coupled to control means (160,162,164) responsive to the different intensities of the reflected light received by a light receiving element of the photosensing means (50) from the first and second reflecting members (82,84).
