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: A feeding system in a printing apparatus is disclosed. For example, the feeding system includes a feed roll, a retard roll, a movable arm, a spring and a temperature dependent flexible material. The movable arm is coupled to the retard roll. The spring is coupled to the movable arm. The temperature dependent flexible material is located below the spring to move the retard roll towards the feed roll via the spring coupled to the end of the arm to maintain a nip force applied by the retard roll against the feed roll as a temperature in a location of the printing apparatus changes.

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: What is disclosed is an apparatus and method for calibrating an optical module of a document scanning device. In one embodiment, imaging sensors of an optical module of the scanning device are used to obtain an image scan of a calibration strip mounted on a surface of a platen on which a sheet to be scanned has been manually placed. The calibration strip has a first vertical line at a first distance from a right edge of the strip, a second vertical line at a second distance from a left edge of the strip, and a sloping horizontal line positioned between the first and second vertical lines. A slope of the horizontal line is non-zero. In a manner more fully disclosed herein, the image scan of the calibration strip is to obtain calibration measurements. The calibration measurements are, in turn, used to calibrate the scan head of the optical module.

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.
