  • Patent number: 9529559
    Abstract: An image forming apparatus is provided with USB sockets on front and back sides, and includes a determining unit for determining whether or not a USB device inserted to a front side USB socket 184 is a function enhancement device, and a control unit making, when it is determined by the determining unit that a function enhancement device is inserted to the front side USB socket 184, the USB device unusable and making, when it is determined that a USB device other than the function enhancement device is inserted, the USB device usable. Thus, it is possible to prevent a USB wireless LAN adapter or the like from being used constantly connected to the front side USB socket and thereby to reduce possibility of USB wireless LAN adapter of being damaged or removed.

  • Publication number: 20160223978
    Abstract: An image formation device includes a power controller that controls transition to an energy-saving mode to reduce power consumption in a standby state and starts up out of the energy-saving mode and a timer in which a timing schedule that starts up the device out of the energy-saving mode is set. The power controller controls the surface temperature of the fixing roller of the image generator to be a temperature lower than the fixing temperature that enables image formation when the image formation device is started up out of the energy-saving mode according to the timing schedule set in the timer.

  • Patent number: 7899664
    Abstract: Even in the case of an information processing apparatus different from a computer usually used by a user, the same kana-kanji conversion candidates as the computer are acquired without unifying Japanese-language converting programs and unifying usage environments. The computer comprises a kana-kanji converting portion that receives a character string from an information processing apparatus through a network to return conversion candidates. The apparatus displays the conversion candidates.

  • Patent number: 6860586
    Abstract: An image forming apparatus of an ink-jet type of the present invention is provided with an ink head section having a carriage that is composed of a plurality of ink head and scans so as to print. The ink head section is provided with black ink heads and a color ink head in such a manner that the black ink heads sandwich the color ink head. This eliminates the difference in blackness in printing, even if the carriage scans in two ways so as to print. Meanwhile, the ink heads are increased in number only by one, thereby limiting an increase in cost. In short, without a large increase in cost, it is possible to provide an image forming apparatus that forms a high-quality image, while printing time is shorted since the printing is carried out in two ways in a scanning direction.

  • Patent number: 6840596
    Abstract: An ink-jet image forming method forms an image by forming dots using a fast-drying ink and a slow-drying ink, in which, when forming an image, an ambient temperature of an area where the image is formed is detected, and dot density of a predetermined area of the image is recognized based on image data. A process used to form dots is selected based on the detected ambient temperature and the recognized dot density. Under the condition where the inks are easily dried, the slow-drying ink is used to form dots, and under the condition where it is difficult to dry the inks, the slow-drying ink is used suitably with the fast-drying ink to form dots. As a result, the inks can be dried efficiently while suppressing deterioration of image quality.
