Abstract: A consumable supply item for an imaging device holds an initial or refillable volume of ink. A housing defines an interior having a pair of opposed electrodes. The electrodes have a capacitance that varies in response to an amount of liquid between them. A controller energizes one electrode and receives an output reading from the other. The controller processes the reading on board the housing and supplies it as a digital data stream to the imaging device during use. A memory stores calibration values for an empty and full housing. The controller writes back to the memory present fluid levels obtained from the output reading of the electrode. An enable output allows operation or not of a fluid pump in the imaging device. Materials, construction, modularity, and fluid communication ports are further embodiments, to name a few.

Abstract: A RFID linking device-based switchable sensor can be used to detect an unseated condition of one component with another component. The switchable sensor includes a RFID linking device, such as a RFID tag, with an electrical circuitry mountable on the one component and a switchable device incorporated with two portions of the electrical circuitry physically and electrically separated from one another such that the switchable device is exposed and normally in a first condition disabling the RFID linking device to a communicatively unavailable state. The switchable device is accessible from externally of the switchable sensor and thus switchable to a second condition, due to contact with an actuator element on the other component, enabling the RFID linking device to a communicatively available state in response to the one component being placed in the seated condition with the other component.

Abstract: An image forming device may be upgraded through scanning an encoded upgrade sheet. A controller and associated circuitry in the image forming device may extract upgrade data, including firmware data for the device, from the scanned upgrade sheet and write the data to a memory device. The upgrade sheets may include an image comprising a pattern of data blocks, with each block having a color shade representative of binary data. The upgrade sheets may be distributed to users in different manners, including mailing upgrade sheets, electronically mailing the image, or providing the image on a network accessible to the users. The upgrade sheets may include a preamble that triggers the upgrade procedure as well as header and footer information describing the upgrade data.

Abstract: A method of operating an imaging apparatus having a duplexer and a perforation device for processing a sheet of media having a first surface and a second surface opposite to the first surface includes forming an image on the first surface of the sheet of media; advancing the sheet of media through the duplexer; and forming a plurality of close-spaced perforations on the sheet of media from the second surface toward the first surface.

Abstract: An apparatus for perforating a sheet of media includes a perforation forming mechanism including at least one perforation device. The perforation forming mechanism is configured to drive the perforation device through the sheet of media to extend through the sheet of media by a distance.

One embodiment of the invention provides an image capture and printing device for creating a scanned image of an item or an original image. The device includes a user interface configured to present a plurality of capture-to functions and to receive input from a user indicating a selection of at least one of the plurality of capture-to functions; an image capturer configured to capture an image, where the size, shape, or intensity of the image, or a combination thereof is based upon the selected capture-to function; and a print engine configured to print the captured image as a background layer in a copy.

Abstract: Method for printing an image on a print medium having an edge or an edge portion. A printer adapted to print the image by printing dots is obtained. Dots are printed beyond a preselected distance from the edge or edge portion at a first percent of print dot density. Dots are printed at and within the preselected distance from the edge or edge portion at a varying percent of print dot density, wherein the varying percent steps down and not up at least two times as the distance from the edge or edge portion of dots to be printed decreases. In one example, the printer is an inkjet printer.
