Abstract: There is provided a tape drive. The tape drive comprises first and second spool supports on which spools of tape may be mounted. The tape drive further comprises an optical sensing system. The optical sensing system comprises a radiation emitter and a radiation detector, said radiation emitter and radiation detector having a fixed positional relationship in use with respect to said first and second spool supports. The tape drive further comprises a controller. The controller is operative to, energise the radiation emitter to emit radiation, and determine a diameter data indicative of a diameter of a spool mounted on one of the first and second spool supports based on a radiation signal generated by the detector.

Abstract: A printer comprising a printhead configured to selectively cause a mark to be created on a substrate. The printer comprises a stepper motor having an output shaft coupled to the printhead, the stepper motor being arranged to vary the position of the printhead relative to a printing surface against which printing is carried out, and to control the pressure exerted by the printhead on the printing surface. The printer further comprises a sensor configured to generate a signal indicative of an angular position of the output shaft of the stepper motor. The printer further comprises a controller arranged to generate control signals for the stepper motor so as to cause a predetermined torque to be generated by the stepper motor; said control signals being at least partially based upon an output of said sensor.

Abstract: A printer comprising a printhead configured to selectively cause a mark to be created on a substrate, a stepper motor having an output shaft coupled to the printhead, the stepper motor being arranged to vary the position of the printhead, a sensor configured to generate a signal indicative of an angular position of the output shaft of the stepper motor, and a controller arranged to generate control signals for the stepper motor. Said control signals being at least partially based upon an output of said sensor and at least partially based upon a target position. Said control signals for the stepper motor are arranged to cause a magnetic field to be generated by windings of the stepper motor. A field angle being defined between an angular position of the output shaft of the stepper motor, and an orientation of the generated magnetic field. Said control signals comprise a first control signal configured to cause said field angle to have a predetermined value, and a second control signal configured to cause said magnetic field to have a predetermined magnitude, and said controller is configured to vary said first and second control signals based upon said target position and said output of said sensor.

Abstract: A labelling machine comprises a supply spool support for supporting a supply spool comprising label stock; a take-up spool support adapted to take up a portion of the label stock; a motive device configured to propel the label stock along a web path from the supply spool support towards the take up spool support; a first arrangement configured to produce a first signal indicative of a speed at which label stock is removed from the supply spool by the motive device; a controller configured to receive the first signal and output a brake assembly control signal based upon the first signal; and a brake assembly configured to apply a braking force to the supply spool support based upon the brake assembly control signal, the braking force resisting rotation of the supply spool support. The controller is configured to output the brake assembly control signal based upon a target supply spool speed.
