摘要： One or more printers or printing systems are connected to a scanning device. Each printer includes one or more color modules that are used during a printing operation. A printer prints a target for each color module or color channel. The printed targets are then scanned by the scanning device. The printed targets may be rotated to any angle and then scanned by the scanning device. The scanned raster data is processed by a controller to detect non-uniformities in at least one density image and to generate one or more correction profiles for the printer. When an image is to be printed, one or more controllers receive the image data and use the one or more correction profiles to correct or compensate for the non-uniformities during the exposure process.

摘要： An electro-optical device includes a controller, a reference current source, a correction current source, a combining unit, and an electro-optical element. The controller generates a reference current control signal defining a first period during which a reference current is output, and a correction current control signal defining a second period during which a correction current is output, the second period being shorter than the first period. The reference current source generates the reference current based on the reference current control signal. The correction current source generates the correction current based on the correction current control signal. The combining unit combines the reference current and the correction current to generate a driving current. The electro-optical element emits an amount of light corresponding to the driving current. The controller generates the reference current control signal and the correction current control signal so that the second period is shorter than the first period.

Each array includes a plurality of light emission elements arrayed in a second direction which is perpendicularly to the first direction. The light emission elements emit light for forming an electrostatic latent image on a photosensitive surface of an image carrier. A switcher activates the light emission elements in at least one of the element arrays while deactivating the others. A developer develops the latent image as a visible image with toner.

摘要： Apparatus and methods for adjusting a skew angle of an LED array in the second of dual/tandem print engine systems to compensate for shrinkage of the printable medium exiting the first print engine. Features and aspects hereof provide for manually and/or automatically measuring the shrinkage of the printable medium as it exits the first print engine and for automatically and/or manually adjusting the skew angle of the mounting of the LED array in the second print engine. The image data applied through the LED to the corresponding photoconductor of the second print engine is similarly skewed to match the skew angle of the LED array. Thus a substantially normal bitmap image is applied through the skewed LED to the photoconductor of the second print engine shrunk in the width dimension. Visual artifacts and anomalies from the mathematical approximations and rounding are visually imperceptible at sufficiently high resolutions.
