Filed:

Jun 27, 2003

Appl. No.:

10/609271

Inventors:

Ricky E. Robbins - Harrodsburg KY

Assignee:

Lexmark International, Inc. - Lexington KY

International Classification:

G01R 2726

US Classification:

324678, 347 14, 347 19

Abstract:

A calibration resistor and a capacitance load are placed in parallel across the output of a voltage source and a first decay time is determined for the voltage to reach a second voltage from a first voltage after the voltage source is disconnected. With the calibration resistor electrically removed, N printheads of a printer and the capacitance load are placed in parallel across the voltage source output. In a first example, the voltage across the capacitance load at a second decay time, which is shorter than the first decay time, is determined and indicates at least one possibly shorted printhead when less than the second voltage. In a second example, the voltage across the capacitance load at the first decay time is determined and indicates at least one possibly shorted printhead when less than a third voltage which is less than the second voltage.

US Classification:

347 8, 347 19, 347 9

Abstract:

A method for determining a printhead gap between a printhead and a sheet of media in an ink jet apparatus that performs bi-directional alignment of the printhead includes determining a first amount of bi-directional misalignment of the printhead at a first unknown printhead gap; changing the printhead gap from the first unknown printhead gap to a second unknown printhead gap by a known printhead gap change amount; determining a second amount of bi-directional misalignment of the printhead at the second unknown printhead gap; and calculating at least one of the first unknown printhead gap and the second unknown printhead gap based on the first amount of bi-directional misalignment, the second amount of bi-directional misalignment, and the known printhead gap change amount.

Abstract:

User-selectable functions for use in output devices to generate background images. 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:

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 imaging apparatus includes an image capturing system. A controller is communicatively coupled to the image capturing system. A scanner body has a scanner opening. The image capturing system is located adjacent the scanner opening. A document planar member is positioned across the scanner opening. The document planar member is communicatively coupled to the controller. The document planar member has an input operating state wherein the document planar member receives at least one input from a user input object and supplies the at least one input to the controller for further processing.

Abstract:

An imaging apparatus includes an image capturing system. A controller is communicatively coupled to the image capturing system. A scanner body has a scanner opening. The image capturing system is located adjacent the scanner opening. A document planar member is positioned across the scanner opening. The document planar member is communicatively coupled to the controller. The document planar member has a transparent state wherein the document planar member is clear and having a translucent state wherein the document planar member is translucent. The controller executes program instructions to control the document planar member to display scan operation related indicia formed by controlling a first portion of the document planar member to be in the transparent state and controlling a second portion of the document planar member to be in the translucent state.
