    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 method for monitoring a characteristic of a printed image of a thermal transfer printer. The method comprises providing a ribbon and a substrate at a printing location of the thermal transfer printer. The method further comprises printing an image on the substrate at the printing location by transferring ink from a region of the ribbon in a printing operation, a negative image being formed on the region of ribbon. The method further comprises transporting the region of ribbon, by a ribbon transport system, from the printing location towards an imaging location along a ribbon transport path. The method further comprises when a characteristic of the ribbon transport meets a predetermined criterion, obtaining, by an image capture system, a ribbon image of the negative image. The method further comprises processing said ribbon image to generate data indicative of the characteristic of the printed image.

    Abstract: A binary array ink jet printhead assembly includes a cavity for containing ink, nozzle orifices in fluid communication with the cavity for passing the ink from the cavity to form droplets, the nozzle orifices extending along a length of the cavity, and an electrode assembly. The electrode assembly includes a front face configured to be disposed generally parallel to a plurality of droplet paths of droplets from the nozzle orifices. A plurality of charge electrodes are disposed on the front face, each charge electrode corresponding to a droplet path and disposed parallel to the droplet path. Circuitry is disposed on the electrode assembly, wherein each electrode is electrically connected to the circuitry. The circuitry is further in electrical connection to a connector for connecting the electrode assembly to a controller for the printhead.

    Abstract: Embodiments of the invention relate to ink compositions suitable for applications in the printing industry, for example continuous inkjet printing, including ultra-high speed continuous inkjet printing. The ink compositions use volatile organic solvents, a colorant, and one or more binder resins including a resin that is a phenolic resole resin, wherein the ink composition is free of methanol, halogens, halogenated compounds and bisphenol-A. A phenolic resole resin of the ink composition preferably contains less than 0.1% by weight of free formaldehyde. The one or more binder resins including the phenolic resole resin may be present in an amount that is from about 5% to about 30% by weight of the ink composition.
