Abstract: A scanning device includes a transparent platen which receives a sheet to be scanned. A backing assembly is spaced from the platen by the sheet during scanning. The backing assembly includes a backing plate of a fixed color and an electrochromic layer intermediate the backing plate and the platen. The electrochromic layer has a first state in which the electrochromic layer is opaque and has a different color from the fixed color, and a second state, in which the electrochromic layer is transparent to expose the backing plate through it. A sensor is positioned to acquire an image of the sheet based on light passing through the platen. A controller selectively applies a voltage across the electrochromic layer to change the electrochromic layer between the first and second states.

Abstract: A document scanning device includes first and second image sensors spaced along a document path and positioned to scan first and second sides of an input document. A first driven belt is configured to receive the input document directly onto a first surface of the first driven belt and transports the document past the first image sensor, where a first side of the document is scanned. A second driven belt, horizontally spaced from the first driven belt, receives the document after it has been scanned by the second image sensor and transports the document to an output. The device is suited to scanning of a variety of substrates and document sizes, such as normal, small, rigid, or delicate documents as the document path can be substantially straight and provide support for the document during scanning allowing delicate, small or rigid documents to be scanned.

Abstract: An input imaging system and method for adjusting LED light uniformity in an LED array are disclosed. For example, the input imaging system includes an LED array, wherein the LED array is divided into a plurality of different banks of LEDs, wherein a light output of each one of the plurality of different banks of LEDs is independently adjustable, an electrical device for adjusting the light output of the each one of the banks of LEDs coupled to each one of the plurality of different banks of LEDs to achieve the uniform LED light illumination profile, a diffuser coupled to the LED array to scatter the light output towards a document, a lens for collecting the light output that is reflected off of the document and a sensor coupled to the lens to receive the light output that is collected by the lens.

Abstract: An image rendering apparatus and method of operating a center tray of an image rendering apparatus. The image rendering apparatus includes a cavity, and a center tray having a home position located within the cavity and a retrieval position located outside the cavity. The image rendering apparatus further includes a retraction mechanism that is attached to the center tray and an interior wall of the cavity. The retraction mechanism is configured to allow for the extension of the center tray from the home position to the retrieval position, and from the retrieval position to the home position.

Abstract: In order to mitigate image defects caused by unwanted disturbances as a carriage module travels from a continuous velocity transport module across a CVT ramp to a platen module, a bottom surface of the CVT ramp is recessed relative to bottom surfaces of the CVT glass and platen glass to facilitate a smooth transition as the CIS carriage passes the CVT ramp during scanning. An additional carriage button is also provided on the carriage surface to ensure that at least two carriage buttons are biased against the CVT-platen assembly at all times, thereby mitigating vibrational disturbance in the system during scanning motion. The carriage module may be a contact image sensor (CIS) carriage module, a Full Width Array (FWA) carriage module, or a folded Charged Coupled Device (CCD) carriage module.
