Abstract: A coating process for the fabrication of organic photoreceptors employs an electrically conductive single slot die biased to allow an electric field between the die and the ground plane on the photoreceptor substrate. The homogenous coating dispersion is fed through the die at a predetermined gap and rate to control coating thickness at the same time that an electric field is applied. The formulation, rheology, particle mobility, coating speed, electric field and the like are controlled so that the photogenerator particles migrate to the substrate in the dwell time defined by the coating die region.

Abstract: An apparatus and related method for automatically aligning one or more print head modules in an ink jet printing system are provided. A mounting supports and aligns a print head module with respect to three axes of movement. The mounting includes rotatable cams that contact control surfaces connected to the print head module to move the print head module in a desired direction. The related method automatically positions multiple stationary print heads with respect to three axes of movement, including rotational adjustment about a Z-axis. The method also automatically adjusts the position of a single print head with respect to its angular rotation about the Z-axis.

Abstract: A head position management section prereads image data as many lines as the print width of a black head divided by the number of print divisions in a black mode, if the image data is black only, updates the head position, performs vertical scanning control, and instructs an image preparation section to transfer print data as wide as the print width from an image memory to a band buffer. If color data exists at the preread time, a mode change point is set in the line immediately preceding the color data. With the head position set to the mode change point, vertical scanning control is performed and horizontal scanning is repeated at the position as many times as the number of divisions. At the time, the transfer area of print data by the image preparation section is reduced in sequence and the image to the mode change point is completed. Then, the print mode is changed to a color mode and print is continued.

Abstract: A color image of a dot-sequential system is converted into a color image of a field-sequential system and a color image can be encoded/decoded at a high speed with a high compression ratio. A pixel value of image data of a dot-sequential system is sequentially inputted to a reference area generating means, and the reference area generating means outputs target pixel data and reference area data. A same pixel value distributing and generating means generates and outputs a same pixel value distribution from the target pixel data and the reference area data. A predictive information encoding means encode data in accordance with an encoding generating table, and outputs predictive information encoded data and an encoding result signal. A dot-sequential/field-sequential image converting means converts pixel data of dot-sequential system into image data of field-sequential system when data cannot be encoded.
