  • Publication number: 20170171283
    Abstract: A communication apparatus includes a receiver and circuitry. The receiver receives image data from a transmission apparatus. The circuitry identifies an image data type of the image data received by the receiver, and determines a transmission data capacity to be used for transmission of the image data at the transmission apparatus based on the identified image data type. The circuitry further sends a notification to the transmission apparatus, the notification requesting the transmission apparatus to transmit the image data based on the determined transmission data capacity, and outputs the image data that the transmission apparatus transmits based on the notified transmission data capacity.

    Abstract: An image forming apparatus includes a transfer member configured to abut against an image carrier for carrying a toner image to form a transfer nip; and a power supply configured to output a bias voltage for transferring the toner image on the image carrier onto a recording medium nipped in the transfer nip. The bias voltage includes a first voltage for transferring the toner image from the image carrier onto the recording medium in a transfer direction and a second voltage having an opposite polarity of the first voltage, the first and the second voltages being alternately output. A time-averaged value of the bias voltage is set to a polarity in the transfer direction and is set in the transfer direction side with respect to a median between a maximum and a minimum of the bias voltage.

  • Publication number: 20170095924
    Abstract: The present invention relates to a teaching data preparation device and a teaching data preparation method for an articulated robot. Pre-existing position data that approximates new position data is retrieved from a database that, from among data related to working points for a pre-existing workpiece, stores for each working point pre-existing position data that indicates the position of the working point and pre-existing orientation data that indicates the orientation of an end effector at the working point. Next, pre-existing orientation data that is associated with the retrieved pre-existing position data is extracted. Next, incomplete new orientation data is completed using the extracted pre-existing orientation data. As a result of this series of processes, the precision of teaching data can be improved.

  • Patent number: 9551956
    Abstract: An image forming apparatus is provided. The image forming apparatus includes a photoconductor, an irradiator, a developing device including a developing roller, a development bias applying device, a toner supplying roller and a supply bias applying device, and a controller. The controller changes supply bias offset by reference to at least one of five parameters including photoconductor travel distance, operation temperature of the developing device, operation humidity of the developing device, continuous operating time of the developing device, and color information of image to be produced. After changing the supply bias offset, the controller forms plural toner patterns for image density adjustment on the photoconductor by changing the development bias, and sets the development bias to a certain bias based on the image densities of the plural toner patterns so that the image produced by the developing device has a targeted image density.
