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.
摘要翻译：一个按需喷墨打印头具有一个腔室，多个液体通道进入和离开所述腔室，使得液体连续地移动到腔室中到与喷嘴开口相邻的停滞点，在那里液体基本上静止并且从停滞点离开室，使得在液体通道内的液体流导出的力的矢量和是中性的。与室相关联的致动器适于选择性地增加在停滞点处的液体的压力，从而从喷嘴开口喷出液滴。在液滴喷射之后，系统内部的连续流体流动减少了直接在喷嘴开口后面重新填充防火室的时间。这又大大增加了系统的响应时间。

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 printing on a moving print medium in a printing system is disclosed. The method includes providing a linehead defining one or more print zones. A plurality of transport rollers are provided, wherein at least one transport roller is disposed opposite the linehead, adjacent to the second side of the print medium, and aligned with one of the print zones. A vacuum assembly is disposed opposite the second side of the print medium and includes a vacuum manifold aligned with the aligned transport roller. The print medium is moved through the printing system and a vacuum force operates on the print medium such that at least a portion of the print medium is deflected thereby increasing a wrap angle of the moving print medium around the aligned transport roller. Liquid is jetted from the linehead onto the print medium to form a print.
