  • Publication number: 20080075486
    Abstract: In an image forming apparatus which forms an image by transferring, onto sheets fed by a feeding unit at the first feeding interval, a toner image formed on a photoconductor or intermediate transfer member, if the temperature of a fixing unit which fixes an image transferred onto a sheet falls outside a set temperature range, the sheet layout is changed to a feeding interval wider than the first feeding interval. Whether to perform adjustment processing is determined based on determination of an image forming condition. If the feeding interval is changed to a wider one in the feeding interval changing step during image formation and it is determined in the determination step to perform adjustment processing, toner patch images are formed in an area where no toner image is formed on the photoconductor or intermediate transfer member. The adjustment processing is performed based on reading toner patch images.

  • Patent number: 7200366
    Abstract: A data communication apparatus as a device. A discrimination data of own device is sent. When the discrimination data is received from another device, the discrimination data is stored as a direct communicatable device for the own device. A direct communicatable device list including the stored discrimination data is generated and sent with the discrimination data of the own device. When the direct communicatable device list is received from other device, the direct communicatable device list is stored as an indirect communicatable device for the own device. In response to selection of the discrimination data as a destination address from the discrimination data of the direct communicatable device and the indirect communicatable device, data with the destination address is sent. When the data is received from other device, the destination address of the received data is decided to coincide with the discrimination data of the own device or the direct communicatable device.

  • Publication number: 20070063972
    Abstract: Image control involves receiving source images defined with respect to respective source coordinate systems from source image generators also respectively associated with source IDs. The source images are composed to generate a composite image defined with respect to a composed coordinate system, and the composed image is sent to a viewer which displays the composed image and outputs an HID signal which indicates information defined with respect to the composed coordinate system. A layout manager stores source IDs respectively associated with layout information including position and size of at least one of the source images. An image composer composes the source images according to the layout information. An analyzer analyzes the HID signal for editing layout information stored in the layout manager, and determines a source ID associated with a source image according to the edited layout information.
