Abstract: A system for registration of one or more color separation images on a photoconductor belt prevents misregistration that otherwise can occur between different scan lines and between different latent images due to side-to-side movement of the photoconductor belt. The registration system operates to detect movement of the photoconductor belt (12). Based on the detected movement, the system operates to control modulation of laser beams (46) used to form the latent images to ensure precise registration of the color separation images. As one advantage, the movement of the photoconductor belt can be detected precisely and inexpensively by a photodetector (92) scanned with the same laser beam used for imaging, the photodetector being disposed adjacent the edge (62) of the photoconductor belt.

Abstract: A system for registration of color separation images on a photoconductor belt (12) in an imaging system operates to detect (76) a position of an edge of the photoconductor belt (12). The registration system detects the position with the same laser scanner used for forming latent images on the photoconductor belt. The registration system includes a belt steering control (103) system that steers the photoconductor belt (12) based on the detected position to reduce deviation of the belt from a continuous transport path. The registration system also may include a scan control system (88) that, based on the detected position, controls the modulation of laser beams scanned to form latent images on the photoconductor belt (12). By controlling belt steering (103) and laser beam scanning (88), the registration system maintains the image quality of a final multi-color image upon transfer of registered color separation images to an output substrate.

Abstract: An apparatus and method useful within an imaging apparatus which is capable of producing a multi-colored image on a medium from image data in an electrophotographic system comprises a photoreceptor (110) on which a plurality of electrostatic images can be captured. The photoreceptor (110) can be driven through a photoreceptor path and caused to be transported at a cyclically varying velocity. A plurality of exposure devices (130) direct light beams (132) which strike the photoreceptor (110) at various locations along the path, the lengths between where the beams (132) strike is such that a plurality of images can be registered relative to each other and such that the registrations account for the cyclically varying velocity. The photoreceptor (110) can be driven by a stepper motor (134) and scanned once with each step of the stepper motor (134) or once for a plurality of discrete steps.

The system for registering multiple image planes of a single image in an electrographic system includes a receptor drum capable of capturing two or more overlaying image planes, an exposure device for forming overlaying image planes on the receptor drum, and at least one developer station transferring a developer to the receptor drum corresponding to each of the overlaying image planes. A measuring device is provided for measuring the rotational position of the receptor drum. A drive mechanism is provided for controlling a motor coupled to the receptor drum by at least one drive belt. A closed loop positioning system is coupled to the measuring device and the drive mechanism. The closed loop positioning system is capable of modulating the angular velocity of the receptor drum to achieve image plane registration of the two or more image planes. The system is capable of achieving image plane registration error of preferably about 100 νm or less, more preferably about 50 νm or less, and most preferably about 20 νm or less. The system is capable of achieving image plane registration error of about ± 0,5 scan lines or less.

Abstract: A scanner module for use in an imaging system includes a laser scanner operable under control of the imaging system for scanning a laser spot along a scan line to write a plurality of pixels along the scan line. The scanner further includes a scanner module memory including pixel placement correction data downloadable to the imaging system for use in controlling the placement of pixels along the scan line. The scanner module memory may further include output power correction data downloadable to the imaging system for use in controlling the output power of the laser scanner in the generation of the plurality of pixels along the scan line. Imaging systems use the correction data stored in the one or more replaceable scanner modules for use in controlling the placement of pixels along the scan line and/or for use in controlling output pwer of the laser scanner. Systems and methods for generating the correction data for the laser scanner modules are also described. Scan correction data can be used to reduce differences in the scan profiles of multiple scanners, such that the multiple scanners produce substantially the same scan profile. In this manner, color planes formed using multiple scanners can be placed in substantial registration with one another, thereby alleviating the visual effects of scan profile differences from scanner-to-scanner.
