Abstract: An imaging device having an imaging unit for illuminating and capturing an original positioned on the imaging surface. The imaging surface is illuminated by an illumination system including a plurality of light sources that non-uniformly illuminates the imaging surface such that the corner areas of imaging surface is illuminated more than the non-corner areas of the imaging surface. In one embodiment the light sources are arranged around the perimeter of the imaging surface. In an alternate embodiment the light sources are located outside the field of view of a lens of the image capturing unit.

Abstract: A method for reducing time in performing an imaging function by an imaging device. The method includes receiving at least one media sheet against an image capture window of the imaging device, detecting whether a lid for covering the image capture window is closed, capturing an image of the at least one media sheet in the image capture window in response to detecting a closed lid, receiving a start signal indicative of a user request to start an image capture operation after capturing the image, and sending a final image based upon the captured image to a destination.

Abstract: A method for reducing specular reflection in an image. The method includes capturing a first exposure of a scan surface using a first of a plurality of light sources, capturing a second exposure of a scan surface using a second of a plurality of light sources, determining which pixels captured by the light sources are speckles, and replacing a value of at least one speckle in the image with a different pixel value.

Abstract: An imaging device including a base and an enclosed chamber positioned on the base. The enclosed chamber has a scanning surface inclined with respect to the base, a reflecting member positioned opposite to the scanning surface and an imaging member adjacent the scanning surface and oriented towards the reflecting member. The imaging member is illuminated with a red, a green, a blue, and an additional color LED. In one embodiment the additional color is a color other than red, green, and blue. In an alternate embodiment the additional color is Ultraviolet (UV) or Infra-Red (IR).

Abstract: A resolution quality redefinition control system for a multi function scanner/printer controls a plurality of functions executable such as scanning, printing, copying and faxing. Multiple resolution qualities may be selected by a user for any of the functions through a user input in communication with the controller. A designated quality resolution may not be appropriate for a designated function, however. Some of the functions have an optimal resolution and/or a significant range of resolutions. When the designated quality resolution is not appropriate for a designated function, the controller re-defines the designated quality resolution as an execute resolution for each execution of one of the functions.

Abstract: Multiple enhancements are provided to a smart copy function of an imaging device to improve performance by making it operate in a time efficient manner. The enhancements include determining pre-positioning of the scan bar based upon the content type setting in the user interface. The smart copy function is also enhanced by determining when to implement and implementing a second pre-scan at a higher resolution when misidentification occurs. Another enhancement uses original size and edge to edge properties to determine content of the original document, which then allows optimal selection of the final copy scan and print parameters.

Abstract: A removable duplex unit for an image forming peripheral having a simplex media feedpath and a reversible roller for moving media in a first direction through the peripheral and in a second direction through the duplex unit, includes an auxiliary housing adapted to be removably connected to the image forming peripheral, the auxiliary housing having therein a curved duplex media feedpath of a preselected length extending through the auxiliary housing in feeding communication with the reversible roller in the simplex media feedpath wherein the duplex feedpath in the auxiliary housing is passive and does not provide energy to media passing through the duplex media feedpath.

Abstract: A method for scanning a document and printing a copy with improved efficiency is provided. The method includes scanning the document with a first resolution, determining a content type of the scanned document while scanning at the first resolution and determining an optimum scanning resolution based on the content type. Rescanning the document at the optimum resolution if the first resolution does not correlate with the optimum resolution, selecting a print setting based on the content type and printing the copy using the print setting.

Abstract: A coating apparatus for applying a coating liquid to a printing substrate. The apparatus includes a rotatable first roll, and a rotatable second roll positioned adjacent to the first roll and defining with the first roll a first nip through which the printing substrate passes. The apparatus also has a metering device for applying a layer of coating liquid onto the second roll, which in turn transfers the coating liquid to the printing substrate. The apparatus further has a controller that communicates with at least the second roll, wherein the controller performs the steps of determining whether the idle time of the second roll is longer than a predetermined threshold, setting a pre-spin flag if the idle time of the second roll is longer than a predetermined threshold, and directing the second roll to perform a pre-spin upon the presence of the pre-spin flag.

Abstract: A method of improving a sealing between a purge mechanism and a printhead includes the steps of providing a purge cap with a perimetrical sealing lip; and exercising the perimetrical sealing lip of the purge cap against the sealing surface of the printhead. The exercising is effected by generating a repetitive relative movement between the sealing surface of the printhead and the perimetrical sealing lip of the purge cap.

Abstract: A method of positioning an ink jet printhead in a printer includes dividing a bitmap into a plurality of rows of tiles. A subset of the rows of tiles to be printed in a next pass of the printhead is identified. Printable ones of the tiles in the subset of rows are identified. The printable tiles contain printable data. Within each printable tile, a top most location of the printable data and at least one of a left most location of the printable data and a right most location of the printable data are identified. A print medium is advanced in a feed direction until a portion of the print medium corresponding with the top most location of the printable data of at least one printable tile is substantially aligned with a top nozzle of the printhead.
