    摘要: Xerographic printing system using a Raster Output Scanning (ROS) system incorporating a two wavelength (.lambda.) laser diode source for the ROS and a charge retentive member in the form of a belt or drum structure which is responsive to the two wavelengths. The printing system utilizes a CAD development system in addition to two DAD developments during the second pass for enabling the addition of a gamut broadening color resulting in process color imaging with an enhanced gamut.

    摘要: Full color, single pass and two-pass imaging processes using black, magenta, cyan and yellow toners and Non-interactive Development without fringe field development. Corona discharge is utilized for voltage leveling certain developed images prior to their passage through DAD developer housings. A Raster Output Scanner (ROS) used for creating the latent electrostatic images is also used for voltage leveling of images developed on the first pass of the two pass imaging process in order to remove certain other images for eliminating fringe field images as well as other undesired images.

    摘要: An imaging system is provided which combines the perfect registration capabilities of xerocolography to form perfectly registered red, green and blue images in a single pass in one mode of operation. In another mode of operation, the color gamut possible with RGB toners is extended using black toner to develop an image that is formed using a second imager or exposure device. The result is an extended gamut color imaging process using four colors side by side in a single pass with a minimum amount of color desaturation and with a minimum number of image registrations. Yet another mode of operation provides for creating K+2 colors in a single pass. The three or two colors may be used to form highlight colors and/or logo colors.

    摘要: Creation of multiple color images is accomplished in a single pass utilizing a multilayered photoreceptor structure having layers which are responsive to different wavelength lasers. A composite image including three images areas is formed with substantially perfect registration. A CAD and DAD image are developed using CMB development and a second DAD image is developed using a non-interactive development system. Development of the second DAD image without developing halos around the CAD image by recharging the photoreceptor prior to development of the second DAD image.

    摘要: Full process color imaging is provided with the use of two xerocolography engines in tandem. Each of the two xerocolography engines is capable of creating three perfectly registered latent images with subsequent development thereof in a spot next to spot manner. Each engine is provided with three developer housing structures containing five different color toners including the three subtractive primary colors of yellow, cyan and magenta. Two of the primary colors plus black are used with one of the engines. The third primary color is used with the second tandem engine which also uses one of the primary colors used with the first engine as well as a fifth color which may be a logo or a gamut extending color. The full process color imaging capability provided is effected without any constraints regarding the capability of the laser imaging device to image through previously developed components of a composite image. Also, the development and cleaning field impracticalities imposed by quad and higher level imaging of the prior art are avoided. Moreover, the number of required image registrations compared to conventional tandem color imaging is minimal. Therefore, only one registration is required compared to three or four by conventional tandem engine imaging systems.

    摘要: Full color, two-pass imaging process using black, magenta, cyan and yellow toners and Non-Interactive Development (NID) without fringe field development. A switchable wavelength flood lamp structure is provided for producing blue and red light. One wavelength is used during the first pass of a photoreceptor through various processing stations for revealing an imagewise voltage for development with magenta toner using an NID system. The other wavelength is used during a second pass of the photoreceptor for revealing another imagewise voltage to be developed with magenta toner.
