摘要： A system is described for tracking a position of a receiver medium as it travels along a media path. A laser provides heat to the receiver medium in a localized area sufficient to permanently alter a physical property of the receiver medium thereby forming a reference mark. A sensor at a downstream position along the media path is adapted to sense the reference mark providing a sensed signal. The sensed signal is analyzed to determine a position of the receiver medium as the receiver medium passes through the second position along the media path by detecting a position of the reference mark.

摘要： A printing system for printing on a print medium is disclosed. A first linehead is disposed opposite a first side of the print medium. The first linehead defines print zones where a liquid is deposited onto the first side of the print medium. A plurality of transport rollers are disposed adjacent to the second side of the print medium. At least one transport roller is aligned with one of the one or more print zones of the first linehead. A vacuum manifold is disposed opposite the second side of the print medium. The vacuum manifold is aligned with the aligned transport roller and outputs a vacuum force that operates on the second side of the print medium to deflect the print medium causing an increase in the wrap angle of the print medium around the aligned transport roller.

摘要： A method for color density correction in a printing system that includes a linehead, with one or more printheads, that jets ink onto a moving print media and an integrated imaging system that captures images of content printed on the moving print media is provided. One or more pixel data values and a measured density value trace for a printed test block are produced by scanning the test block and averaging pixel data in a print media transport direction. A color and a density of the ink in the printed test block are determined using the pixel data values. The measured density value trace is compared with a respective reference density value. It is determined whether there is a difference between the measured density value trace and a reference density value is determined. If there is a difference, ink laydown for the printhead is adjusted based on the difference.

摘要： A drop on demand ink jet print head has a chamber with a plurality of liquid passages into and out of said chamber, such that liquid is continuously moved into the chamber to a stagnation point adjacent to the nozzle opening, whereat the fluid comes substantially to rest, and out of the chamber from the stagnation point such that vector sum of liquid flow derived forces within the liquid channels is neutral. An actuator associated with the chamber is adapted to selectively increase the pressure of the liquid at the stagnation point to thereby eject a liquid drop from the nozzle opening. Continuous fluid flow internal to the system decreases the time to refill the fire chamber directly behind the nozzle opening after droplet ejection. This in turn dramatically increases the response time of the system.
