20080304847 | IMAGE-FORMING APPARATUS, AND CONTROL METHOD, PROGRAM AND STORAGE MEDIUM THEREFOR - An image-forming apparatus capable of satisfactorily maintaining the durability of a separating mechanism while preventing deformation of rubber layers of parts of a fixing unit and at the same time achieving a power saving effect. The image-forming apparatus is shifted into a power saving state without a fixing part and a pressurizing part of the fixing unit being separated. The fixing part and the pressurizing part are separated, if a return condition from the power saving state is not satisfied even after elapse of a predetermined time period from when the apparatus has been shifted into the power saving state. | 12-11-2008 |
20090284792 | PROCESSING APPARATUS, METHOD OF CONTROLLING THE SAME, AND STORAGE MEDIUM - A processing apparatus enabling initial settings to be easily configured as a user desires e.g. upon purchase of the apparatus without unpacking the apparatus from a shipping carton. The processing apparatus comprises a wireless communication unit operable by an AC power supply or a battery, and an EEPROM operable by the AC power supply or the battery and stores initial settings information for the apparatus. An MCU of the processing apparatus determines whether electric power is currently supplied from the AC power supply or from the battery. Further, the MCU determines whether or not power-on history information on the AC power supply has been stored. When the battery is used and no power-on history information has been stored, the MCU rewrites the initial settings information stored in the EEPROM, based on initial settings information received from a dealer's PC by wireless communication. | 11-19-2009 |
20100277755 | INFORMATION PROCESSING APPARATUS CONNECTED TO A PRINTING APPARATUS VIA A NETWORK AND COMPUTER-READABLE STORAGE MEDIUM HAVING STORED THEREON A PROGRAM FOR CAUSING A COMPUTER TO EXECUTE GENERATING PRINT DATA IN THE INFORMATION PROCESSING APPARATUS CONNECTED TO THE PRINTING APPARATUS VIA THE NETWORK - An information processing apparatus connected to a printing apparatus via a network encrypts print data if identification information is input, and does not encrypt print data if identification information is not input. If identification information is input and the print data has been encrypted, the information processing apparatus sends a print job including the encrypted print data to the printing apparatus via the network; otherwise, the information processing apparatus sends unencrypted print data to the printing apparatus via the network. | 11-04-2010 |
20110069338 | PRINT SYSTEM, CONTROL METHOD THEREFOR, INFORMATION PROCESSING APPARATUS, CONTROL METHOD THEREFOR, PROGRAM FOR IMPLEMENTING THE CONTROL METHOD, AND STORAGE MEDIUM STORING THE CONTROL PROGRAM - A print system which are capable of inhibiting simultaneous use of the encrypted print and the box storage to thereby increase the security of print data. A host computer has an encryption function of encrypting print data, and issues a print job for the print data encrypted by the encryption function. A print server receives the issued print job, and has a decryption function of decrypting the encrypted print data of the received print job. A printer has a storage function of storing the print data decrypted by the decryption function, and outputs the stored print data. At least one of the host computer and the print server inhibits simultaneous use of the encryption function and the storage function. | 03-24-2011 |
20110249292 | CONTROL DEVICE CAPABLE OF REDUCING POWER CONSUMPTION AND NOISE - A control device that is capable of reducing power consumption and noise generation. The control device controls output of a clock signal to a data processing circuit that executes data processing in synchronism with the input clock signal. A switching section for switching the image output clock signal between a high-frequency clock signal and a low-frequency clock signal is controlled to output the high-frequency clock signal for data processing when the data processing is executed by the data processing circuit, and output the low-frequency clock signal when the data processing is not executed by the data processing circuit. | 10-13-2011 |
20120106995 | IMAGE FORMING APPARATUS CAPABLE OF COMPUTING POWER CONSUMPTION THEREOF, AND CONTROL METHOD AND STORAGE MEDIUM THEREFOR - An image forming apparatus capable of accurately computing power consumption thereof. First power consumption consumed by a fixing device of the image forming apparatus until the fixing device becomes a state capable of fixing a toner image onto a sheet is computed, second power consumption that includes power consumption consumed by the fixing device to fix the toner image onto the sheet and power consumption consumed by conveyance of the sheet is computed according to at least a sheet type, and third power consumption consumed by an exposure unit of the image forming apparatus to expose a photosensitive member of the image forming apparatus to light is computed according to an image to be formed. Then, a sum of the first to third power consumptions is computed. | 05-03-2012 |
20120219311 | IMAGE-FORMING APPARATUS, AND CONTROL METHOD, PROGRAM AND STORAGE MEDIUM THEREFOR - An image-forming apparatus capable of satisfactorily maintaining the durability of a separating mechanism while preventing deformation of rubber layers of parts of a fixing unit and at the same time achieving a power saving effect. The image-forming apparatus is shifted into a power saving state without a fixing part and a pressurizing part of the fixing unit being separated. The fixing part and the pressurizing part are separated, if a return condition from the power saving state is not satisfied even after elapse of a predetermined time period from when the apparatus has been shifted into the power saving state. | 08-30-2012 |
20120290856 | POWER CONTROL APPARATUS, METHOD FOR CONTROLLING THE SAME AND STORAGE MEDIUM - A power control apparatus uses a job history stored in a second storage unit to update, at a predetermined time interval, a power-off sequence table defining a sequence in which power supply is to be stopped for devices when a smart power meter has requested power supply reduction, inquires the smart power meter regarding the amount of power to be reduced when a power reduction request has been received therefrom, and stops power supply to devices in accordance with the reduction power amount, the device power consumption amounts, and the power-off sequence table. | 11-15-2012 |
20130222833 | IMAGE FORMING APPARATUS, IMAGE FORMING APPARATUS CONTROL METHOD, AND STORAGE MEDIUM - An image forming apparatus including a plurality of interfaces configured to receive external inputs via a network, a display unit configured to display a screen for selecting an interface to be used in a power saving state from among the plurality of interfaces, and a power supply unit configured to supply a power to the interface that is selected on the screen and not to supply a power to a interface that is not selected on the screen in a case where the image forming apparatus enters the power saving state. | 08-29-2013 |
20140240747 | IMAGE FORMING APPARATUS THAT PERFORMS USER AUTHENTICATION BY WIRELESS COMMUNICATION, METHOD OF CONTROLLING THE SAME, AND STORAGE MEDIUM - An image forming apparatus capable of returning from the power saving state and performing user authentication by one action of holding an authentication card over a card reader even when the apparatus is in the power saving state. The apparatus performs short-distance wireless communication with an external device. A controller performs control processing including at least authentication processing. When short-distance wireless communication with the device is started, a short-distance wireless communication section delivers a return-starting interrupt, to the controller, receives authentication data from the device to thereby store the authentication data during returning of the apparatus. The controller performs authentication processing based on the stored authentication data after returning of the apparatus from the power saving state, and notifies the device of an authentication processing result by a different channel. | 08-28-2014 |
