  • Patent number: 10795300
    Abstract: An image forming apparatus includes a power supply board, a driver board, and an engine control board. The driver board includes a plurality of switching elements each configured to supply and shut off a power supply for each of a plurality of distributed power supply voltages supplied from the power supply board. The plurality of switching elements includes a first switching element, to which the power supply voltage is to be applied from the power supply board, and a second switching element, to which the power supply voltage output from the first switching element is to be applied in a distributed manner. The engine control board is configured to performs failure diagnosis of the first switching element when the image forming apparatus is activated, and performs failure diagnosis of the second switching element in a case where an abnormality has occurred in any one of a plurality of loads.

  • Patent number: 9880763
    Abstract: In a case where a non-volatile memory comes close to the end of a life time and has become ReadOnly, it is impossible to erase data stored in the non-volatile memory, which may lead to a decreased robustness of maintaining confidentiality. A data processing apparatus determines whether the life time of a non-volatile memory is about to expire. In a case where the determination result indicates that the life time of the non-volatile memory is about to expire, the data stored in the non-volatile memory is erased.

  • Publication number: 20120030601
    Abstract: An information display control apparatus that is capable of displaying a plurality of filenames on a display unit so that the filenames are easily distinguished and original filenames are easily recognized. A first determination unit determines whether the number of characters of each filename is larger than the predetermined number of characters. A second determination unit determines whether the filenames have a common part. A display control unit displays a part of the filename onto the display unit within the predetermined number of characters and to display the full filename by rolling characters when the first determination unit determines that the number of characters of the filename is larger than the predetermined number of characters. The display control unit changes character rolling speed according to a determination result by the second determination unit when the filename is displayed by rolling characters.
