    摘要： In color printing with a color registration system for the registration of plural color images on an image bearing surface, such as a photoreceptor belt (12) of a color printer, registration marks are imaged on the image bearing surface, which registration marks (32) correspond to the color images and are sensed by a registration marks sensor (22). In an initial gross registration mode the system first automatically images first registration marks (32), in the form of expanded chevron targets, which are greatly expanded in the process direction so as to avoid overlapping marks even if there is initial gross mis-registration, to thus provide wider initial mis-registration latitude for the sensor. When an acceptable initial registration is achieved, the system automatically switches to imaging more closely spaced and more frequent second registration marks (36), preferably regular chevron targets, providing higher registration accuracy. These registration targets may be generated along opposite sides of the image areas, on opposite sides of the photoreceptor (12) or other image bearing surface in the process direction.

The system first automatically images first registration marks (32), preferably "Z" targets, which provide wider initial mis-registration latitude for the sensor (22) for gross registration. When an initial registration is achieved, the system automatically switches to imaging second registration marks (36), preferably chevron targets, providing higher registration accuracy for the sensor (22). These registration targets may be generated along opposite sides of the image area on opposite sides of the photoreceptor (12) or other belt.

    摘要翻译： 在彩色打印机的彩色配准系统中，如彩色打印机的感光带（12）等图像承载面上的多个彩色图像的配准，在图像承载面上成像对准标记（32）， 对应于彩色图像并由对准标记传感器（22）感测。 在初始总注册模式下，系统首先以扩展的人字形目标的形式自动地形成第一注册标记（32），这些目标在过程方向上被大大扩展，以便即使存在初始的粗错配准，也避免了重叠的标记， 从而为传感器提供更宽的初始误配准纬度。 当达到可接受的初始注册时，系统自动地切换到成像更紧密间隔和更频繁的第二对准标记（36），优选地是规则的人字形目标，提供更高的配准精度。 这些配准目标可以沿着图像区域的相对侧，在感光体（12）的相对侧或处理方向上的其他图像承载表面上产生。

    摘要： The present invention is a method and apparatus for compensating for position error inherent in a raster output scanning printing system by adjusting (64) the intensity of image exposure to effect a correction in the output image. The invention is particularly well suited to compensate for position errors arising from a plurality of sources by first summing (62) the errors and then applying a single compensating adjustment to the intensity of individual scan rasters based upon the position error thereof.

    摘要： A method and apparatus for achieving optimum optical contrast for detecting registration marks in a multicolor print-black-first, color electrophotographic printing machine. A black mask having voids in the shape of a registration mark is formed on the photoreceptor (10). A high contrast color is then overwritten on the mask and in the voids, forming marks which indicate the position of the black image. A delay time measurement between a registration mark of a non-black color and the non-black color in the voids of the black mask will provide the relative registration between the black and non-black color imagers as those registration marks on the photoreceptor pass a marks-on-belt sensor. A second method utilizes a registration mark imaged by each imager of the color printing machine, but all of the latent image registration marks are developed with a single non-black color toner. A mark-on-belt sensor is then used to determine the relative position of the various color imagers and to send signals to the controller to make appropriate corrections.
