In an electronic image scanning device having an array of photosensitive elements, or photosites, arranged and supported for deriving electronic image information from an original, an arrangement for input of control information to the device includes a surface with a plurality of unique control images thereon, detectable by the photosites, is arranged for operator controlled movement. The scanning of the control images occurs during a non-image scanning period in the operation of the scanning device. The unique control images are recognized as control information. The operator controlled movement reflects operator selection of control information.

A system for detecting reflectance from an image bearing surface in a printer or electronic copier includes an illuminator array, positioned adjacent to the image bearing surface, comprising a plurality of discrete illuminator elements that are spaced in a linear arrangement; a light diffuser positioned between the illuminator array and the image bearing surface, the light diffuser being positioned with respect to the illuminator array to receive the light beams emitted by the illuminator elements and to diffuse the light beams for transmission to the image bearing surface at an incidence angle; and a linear sensor array positioned adjacent to the image bearing surface such that specular and diffuse portions of the light beams reflecting off the image bearing surface at a reflectance angle bearing are received by the sensors.

Disclosed is a method of adjusting a plurality of optical elements associated with a printing system ROS. According to one exemplary embodiment, sensitivity analysis is performed on a computer model of the ROS system and an optical element alignment sequence is generated to minimize the number of optical element adjustments needed to achieve a predefined ROS performance.

A system for recording an image as digital data comprises a photosensor array and a plenoptic set, including a main lens and a lenticular grating, to enable the photosensor array to obtain plenoptic image data from the sheet. A subset of the plenoptic image data is selected, such as according to a predetermined object distance, to obtain image data for a focused image. The subset of the plenoptic image can be selected after the scanning, so that prescanning of an unusual-shaped image-bearing object, such as an open book, is avoided.

A printing apparatus has a substantially shiny photoreceptor imaging surface, and a photosensor array disposed to receive specularly-reflected light from the imaging surface. A quantity of toner is placed on the imaging surface, and data is derived based on light reflected from the imaging surface. The reflected light is filtered to a color effectively complementary to the toner color. The system avoids noise caused by diffusely-reflected light from powdered toner.

An apparatus for scanning a document comprises a platen for supporting at least a portion of the document; a light source; and an optical element for directing light from the light source to the platen. The optical element defines a plurality of small planar surfaces, the small planar surfaces being arranged in a linear array. Light emanating from a source is reflected from one of the small planar surfaces and emerges substantially perpendicular to an exit surface.

Processes are presented for creating electronic banding compensation profiles for raster output scanner (ROS) devices by printing and scanning a test pattern having a series of strips extending along a process direction and spaced from one another along a cross process (fast scan) direction, analyzing the scanned data to determine facet-specific banding errors corresponding to individual strips, and selectively adjusting banding correction profiles to counteract the banding errors.

A substrate sensor system having a light source for radiating light toward a substrate position, a light sensor system positioned to receive light transmitted or reflected at the substrate, a lens that images the light transmitted or reflected at the substrate onto the light sensor system, and a telecentric stop between the lens and the light sensor system. Beneficially, such substrate sensor systems will include an electrical circuit that produces position information regarding the position of a substrate and/or the position of an image on a substrate.

Image sensor module architecture provides flexible mounting of illuminators in an imaging apparatus with flexible fasteners. The architecture involves one or more LED-based illuminators that may be mounted adjustably to provide high intensity and uniform profile luminescence. The supporting imaging and electronic circuit components are quickly assembled and disassembled from the image sensor module by using a flexible multi-function clip having multiple segments for holding multiple objects together.
