    Abstract: Accurate advance of a media sheet is achieved by carrying the media sheet on a belt loop. An upstream pinch roller holds the media sheet to the belt upstream of the print zone. A downstream pinch roller holds the media sheet to the belt downstream of the print zone. A guide shim extends along the media path from a position upstream of the upstream pinch roller, passed the upstream pinch roller toward the print zone. The guide shim advances with the bottom edge of the media sheet into the print zone to stabilize the trailing edge so as to allow for a smaller minimum bottom margin.

    Abstract translation: 通过将介质片带在皮带环上来实现介质片的精确提前。 上游夹送辊将介质片保持在打印区域上游的带上。 下游夹送辊将介质片保持在印刷区下游的带上。 引导垫片沿着介质路径从上游夹送辊的上游位置延伸,使上游夹送辊朝向打印区域。 引导垫片随着介质片的底部边缘进入打印区域,以稳定后缘,以允许较小的最小底部边距。

    Abstract: An encoding system is described for a media handling system including an endless belt. The encoding system includes encoding indicia associated with the endless belt. A first encoder transducer is responsive to the encoding indicia to provide a first encoder signal. A second encoder transducer is responsive to the encoding indicia to provide a second encoder signal, the second encoder transducer spatially separated from the first encoder transducer. An encoder processor is responsive to the first encoder signal and the second encoder signal to determine position data regarding the endless belt. Interruption of indicia due to a belt seam is accommodated by transferring belt position calculation from one transducer to the other as the seam passes between the two transducers. The processor is adapted to compensate for variations in the encoder indicia pitch caused by belt temperature differentials.

    Abstract: A system for ink short protection for signaling to inkjet printheads includes a differential signaling driver having a first and a second terminal, a differential signaling receiver having a first and a second terminal, a first capacitor in series between the first terminals, a second capacitor in series between the second terminals, and circuitry for reducing charge accumulation on the capacitors. A method for ink short protection and a printing mechanism having such an ink short protection system are also provided.
