Abstract: A uni-directional waste ink removal system cleans ink residue from an electrostatic sensing element of an ink drop detector in a printing mechanism when the electrostatic sensing element, supported by a base, is actuated between an activated position, a storage position, and back to the activated position. The system also includes a scraper and an absorber which first contact the sensing element when the base is in the storage position, thereby ensuring ink residue may be absorbed, and that ink residue is only scraped from the sensing element in one direction as the base is moved to the activated position. A method of cleaning ink residue from an electrostatic sensing element of an ink drop detector, and a printing mechanism having such a unidirectional waste ink removal system are also provided.

Abstract: A printer control apparatus and an algorithm for determining the peak instantaneous speed of a substrate through a thermal ink jet printer and a printer apparatus are disclosed herein. The printer includes a dryer module, a print head module, and a controller. The method includes determining the tolerable peak instantaneous speeds of the substrate through the print head and dryer modules, which by their sequential nature, operate out of phase from one another. The lower of the two speeds is then selected as the optimum instantaneous speed of the substrate through the printer. A controller in the printer carries out methods disclosed herein.

Abstract: A powder composition containing a powder of a modified polymer having a recurring unit containing at least one carboxyl group, the carboxyl groups of part of the recurring units being in the form of a salt with an aliphatic amine having at least 6 carbon atoms, and a powder of a surfactant. The powder composition is used for forming an image on a printing medium, in which method the composition is applied over a surface of a transfer medium to form a layer of the powder. An image of a liquid ink capable of dissolving or swelling the powder is then formed on the layer so that the viscosity of the liquid ink increases when contacted with the powder. The image on the transfer medium is contacted with the printing medium so that the image is transferred to the printing medium.

Abstract: When a print nozzle or other firing element of an ink jet print head fails, printed image quality suffers. In a print head where there are additional printing elements that continue to work and that are adjacent the failed element, a failed firing element can be compensated for by increasing the firing rate of, or firing pulse duration to, one or more printing elements that are adjacent to the failed element. Additional ink deposited on the printing medium will bleed onto areas that are normally printed onto by the failed firing element.

Abstract: An apparatus and method for ink-jet printing on a recording medium is provided which includes the steps of jetting aqueous ink drops on paper in the form of an image. The aqueous ink used is a slow-drying (high-surface tension) ink which does not penetrate the paper/paper fibers for a relatively long time. Prior to penetration of the paper/paper fibers, the water in the droplet is quickly evaporated from the ink while still resident on the paper surface. The evaporation process is substantially completed prior to an additional liquid ink being jetted onto the same or adjoining location of the recording medium. The evaporation is rapid enough to prevent the resident ink from substantially migrating/wicking to any adjacent location or into the recording medium. Further the drying energy is transferred to the resident ink spots from the same direction as the printheads ensuring less energy requirement.

Abstract translation: 提供了一种用于在记录介质上进行喷墨印刷的设备和方法，其包括以图像形式将水性墨滴喷射在纸上的步骤。 使用的水性油墨是一种慢干（高表面张力）油墨，其不会在相对长的时间内渗透纸/纸纤维。 在纸/纸纤维渗透之前，液滴中的水从墨水中迅速蒸发，同时仍然驻留在纸张表面上。 在附加的液体墨水喷射到记录介质的相同或相邻位置之前，蒸发过程基本上完成。 蒸发速度足够快以防止驻留的墨水基本上迁移/吸附到任何相邻位置或记录介质中。 此外，干燥能量从与打印头相同的方向转移到驻留的墨点，确保较少的能量需求。
