20110280598 | Device for Determining and Adjusting Transfer Voltage in an Imaging Apparatus and a Method Thereof - A device and method for determining and applying a transfer voltage in an imaging apparatus is provided. A servo voltage is determined based in part upon a change in an environmental condition. A determination is made whether or not to perform a new transfer servo operation based upon at least one of an amount of time passing since the last transfer servo operation was performed and a comparison of the determined servo voltage and a servo voltage used in a prior transfer servo operation. A transfer servo operation includes charging a photoconductive drum to a charge corresponding to a printing voltage. | 11-17-2011 |
20110293327 | Method for Increasing Useful Life of an Image Forming Apparatus - An image forming apparatus includes a plurality of photoconductive drums, each photoconductive drum transferring a portion of a toner image to an intermediate transfer member. The photoconductive drums are individually rotated to a printing speed such that a downstream photoconductive drum starts rotating prior to an adjacent upstream photoconductive drum starts image transfer. Similarly, an upstream photoconductive drum starts deceleration when its following downstream station has transferred image. | 12-01-2011 |
20120045224 | Method for Delaying the Start of a Gage for Tracking the Life of a Consumable Item for an Imaging Device - A method for delaying the start of a gage for tracking the life of a consumable item for an imaging device according to one exemplary embodiment includes counting the number of revolutions of a rotating imaging component having a correlation with the life of the consumable item and determining whether a predetermined delay threshold is satisfied based on the number of revolutions of the imaging component counted. Until the predetermined delay threshold is satisfied, starting the gage and tracking the remaining life of the consumable item are delayed. | 02-23-2012 |
20120306767 | METHOD FOR EDITING AN ELECTRONIC IMAGE ON A TOUCH SCREEN DISPLAY - A method for editing an electronic image on a touch screen display according to one example embodiment includes detecting a sequence of movement of at least one of a user's fingers on a touch screen display and determining whether the detected sequence of movement matches one of the characters in a font set. If the detected sequence of movement matches one of the characters in the font set, the matched character is entered in the electronic image. If the detected sequence of movement does not match one of the characters in the font set, a representation of the detected sequence of movement is entered in the electronic image. | 12-06-2012 |
20120311476 | SYSTEM AND METHOD FOR PROVIDING AN ADAPTIVE TOUCH SCREEN KEYBOARD - A method for providing a touch screen keyboard according to one example embodiment includes detecting the presence of a user's fingers on a touch screen display. A set of home keys of a keyboard are associated with the detected fingers. The keyboard is displayed on the touch screen display with the home keys positioned at the locations of the detected fingers and additional keys positioned relative to the home keys. | 12-06-2012 |

20130287429 | Cleaner Unit for Removing Waste Toner within an Image Forming Device - A device for cleaning a photoconductive member in an image forming device. The device includes a blade extending across the photoconductive member and having an edge that contacts a surface of the photoconductive member to remove toner therefrom. An elongated seal disposed adjacent the blade extends across a length of the blade such that an opening for receiving removed toner is formed between the elongated seal and the blade. The elongated seal includes at least one tab projecting at each longitudinal end thereof and extending between the blade and the photoconductive member so as to prevent a longitudinal end section of the edge of the blade from contacting the surface of the photoconductive member. | 10-31-2013 |
20140079427 | Method and System for Efficient Duplex Printing - An imaging device, including one or more imaging units for use in transferring toner to media sheets, one of the imaging units being a black imaging unit for transferring black toner; a media transport path having a duplex path, the duplex path having at least one set of rollers for independently moving media sheets through the duplex path; and a controller operatively coupled to the one or more imaging units and the media transport path, for staging one or more media sheets in the duplex path for a period of time. The period of time results in an increase in the interpage gap which may be utilized while the imaging device interrupts a printing operation to perform any of a number of operations. | 03-20-2014 |
20150071686 | Method and Apparatus for Magnetic Brush Retraction in Electrophotographic System - A method and apparatus for retracting a magnetic brush in an imaging device. The apparatus includes a housing containing carrier beads and toner particles; a magnetic structure at least partly disposed within the housing and generating at least one magnetic field; and an endless sleeve disposed around and rotatable about the magnetic structure, at least a portion of the sleeve extending from the housing. During toner development, the magnetic structure is in a first position for developing a magnetic brush of the carrier beads and toner particles along the portion of the sleeve extending from the housing which forms a developer nip with a photoconductor, and during a period of time when toner development is not to be performed, the magnetic structure is in a second position for retracting the magnetic to brush by causing the carrier beads to be positioned against the portion of the endless sleeve extending from the housing forming the developer nip. | 03-12-2015 |
