  • Patent number: 7715777
    Abstract: An image forming apparatus includes an image carrier; a charger that electrically charges the image carrier; an image forming section that forms an electrostatic latent image on the image carrier and develops the electrostatic latent image; a transferring-fixing section that transfers the image from the image carrier and fix the image onto a recording medium; a cleaning member; and a cleaning member moving section. The cleaning member cleans an unnecessary substance adhering onto a surface of the image carrier by abutting against the surface of the image carrier, and is capable of moving between an abutment position and a separation position where the cleaning member is separated from the image carrier. The cleaning member moving section moves the cleaning member from the separation position to the abutment position in accordance with a surface resistance of the surface of the image carrier.

Control input variable values may be determined based on the error-space feedback values and one or more gains. A motor control signal for a motor for each drive roll may be determined based on the control input variable values and the state variables. Each motor control signal may impart a desired angular acceleration for at least one drive roll. The identifying step and each determining step may be performed repeatedly to register the sheet to the desired trajectory.

  • Patent number: 7715037
    Abstract: A communication system and apparatus for a xerographic imaging system for enhanced collaborative communication between the machine user and the remote troubleshooting advisor. The machine includes an imager for showing a selected virtual representation of the machine including an image of the machine illustrating an area of the machine having the troubleshooting need. A communication link exists between the user and the advisor and comprises a bi-directional visualization of a selected virtual representation synchronously displayed to the user and the advisor via respective imagers. An image adjuster is operated by the expert for selective adjustment of the virtual representation to suggest a section of the area of the machine wherein action by the machine user may resolve the troubleshooting need. The selective adjustment is communicated to the machine user through the communication link whereby upon viewing this suggested adjustment, corrective action is suggested to the user.

  • Patent number: 7715728
    Abstract: An optical transmitter includes a light-emitting element, a driving circuit, a temperature detection unit, a storage device and a control circuit. The driving circuit causes, based on an input signal, the light-emitting element to emit an optical signal having a pulse shape. The temperature detection unit detects an ambient temperature of the light-emitting element. The storage device stores temperature characteristics information of the light-emitting element. The control circuit controls the driving circuit based on the ambient temperature detected by the temperature detection unit and the temperature characteristic information stored in the storage device, so that an extinction ratio of the optical signal having the pulse shape becomes substantially constant.

  • Publication number: 20100110117
    Abstract: A method for restoring ink conductivity of ink in an ink reservoir comprises detecting an ink conductivity of an ink volume in an ink reservoir, and comparing the detected ink conductivity to a predetermined ink conductivity operational range. A flush routine is performed in response to the measured ink conductivity being outside of the predetermined ink conductivity operational range. The flush routine includes: disabling ink supply operations to the ink reservoir; emptying the ink reservoir of ink; refilling the ink reservoir with ink; measuring an ink conductivity of an ink volume in the refilled ink reservoir; and comparing the detected ink conductivity to the predetermined ink conductivity operational range. The imaging device is returned to a normal operating mode in response to the measured ink conductivity being within the predetermined ink conductivity operational range after a flush routine has been performed.
