  • Patent number: 10310425
    Abstract: An image forming apparatus includes a detection unit configured to detect an object and a power-supply control unit. The power-supply control unit shifts the image forming apparatus to a second power state, in response to a lapse of a predetermined time following no detection of the object, when a job has not been executed until the detection unit detects no object, after the power-supply control unit shifts the image forming apparatus to the first power state. The power-supply control unit shifts the image forming apparatus to the second power state before a lapse of the predetermined time, when a job has been executed until the detection unit detects no object, after the power-supply control unit shifts the image forming apparatus to the first power state.

  • Publication number: 20170324880
    Abstract: An image forming apparatus capable of switching power state between a first power state and a second power state, which is lower in power than the first power state, shifts from the second power state to the first power state. In a case where the image forming apparatus shifts to the second power state in response to a current time reaching a set time, the image forming apparatus is controlled not to shift from the second power state to the first power state in response to an object approaching the image forming apparatus being detected.

  • Patent number: 9763032
    Abstract: An information processing apparatus capable of notifying a user of a state of data transmission via short-range wireless communication. An NFC tag controller of an MFP as an information processing apparatus holds communication setting information for wireless LAN communication, and transmits the communication setting information to a mobile terminal as an external apparatus, via NFC communication by dividing the information. An interrupt signal generated by the NFC tag controller for notifying completion of transmission of a divided information item to the mobile terminal is detected, and when the number of times of detection of the interrupt signal reaches a predetermined number of times, the user is notified that the transmission of the communication setting information is completed.

  • Publication number: 20170176920
    Abstract: An image forming apparatus capable of shifting to a state where quick activation thereof can be performed in a shorter time period when a power switch is turned off. When the off operation of the power switch is detected, a first state is stored, and when the on operation of the power switch is detected next, the state of the image forming apparatus is shifted to a second state from which the image forming apparatus can return to the first state. When the state of the image forming apparatus is shifted to the second state, time starts to be measured. When the on operation of the power switch is detected in the second state, the value of the measured time is acquired. The image forming apparatus is caused to return to the stored first state depending on the value of the measured time.

  • Patent number: 9582064
    Abstract: An image processing apparatus that is capable of being instructed to power off, by a power switch or a command from an external apparatus, and is capable of executing the restart thereof under appropriate conditions. When power-off is instructed, shutdown is started. Upon completion of the shutdown, if the power switch is on, and at the same time the power-off has been instructed by the power switch of the apparatus, the restart of the apparatus is executed, whereas upon completion of the shutdown, if the power-off has been instructed by a command from the external apparatus, the restart of the apparatus is not executed.

  • Patent number: 9086662
    Abstract: An image forming apparatus capable of performing image formation quickly and reducing power consumption. The image forming apparatus includes an image forming unit that forms images by transferring toners to sheets and fixing the toners onto the sheets using a fixing section. A page count is acquired which is indicative of the number of pages on which image formation can be formed within a time period required before the temperature of the fixing section rises from a first temperature to a second temperature. Then, when it is determined that rendering of PDL data for pages in the page count is completed, if all of the pages in the page count are for the text images, the image forming unit is controlled such that printing is started when the temperature of the fixing section has reached the first temperature.
