20120151229 | DATA PROCESSING APPARATUS, DATA PROCESSING METHOD, AND PROGRAM - A data processing apparatus includes a control unit configured to control data processing, and a communication unit configured to communicate with other apparatuses. The control unit determines, before the control unit shifts to a predetermined power-saving state, a communication speed of the communication unit to communicate with the other apparatuses when the control unit is in the power-saving state, based on an amount of packets received by the communication unit, and sets the determined communication speed for the communication unit. The communication unit communicates with the other apparatuses at the set communication speed, when the control unit is in the power-saving state. | 06-14-2012 |
20120191926 | INFORMATION PROCESSING APPARATUS THAT EXECUTES RESPONSE PROCESS TO RECEIVED INFORMATION, CONTROL METHOD THEREFOR, AND STORAGE MEDIUM STORING CONTROL PROGRAM THEREFOR - An information processing apparatus that is capable of preventing the overwriting of an incoming packet without disconnecting the network connection. The information processing apparatus receives incoming information via a network, stores it into a storage area, and executes a response process thereto. A response processing unit executes the response process to the incoming information. A first change unit switches so that the incoming information is stored into a second storage area after the incoming information, which is a factor to shift to a power mode from a power saving mode, is stored into a first storage area. A second change unit switches so that the incoming information is stored into the first storage area after the response processing unit executes the response process to the incoming information stored in the first storage area. | 07-26-2012 |
20130047019 | DATA PROCESSING APPARATUS AND CONTROL METHOD THEREFOR - When a data processing apparatus according to this invention detects generation of an event to shift from the standby state to the suspended state, it saves the contents of a memory in the standby state in a non-volatile storage device in response to detection of generation of the event, and shifts to the suspended state. When power-off is instructed in the suspended state, the data processing apparatus shifts from the suspended state to the power-off state without the mediacy of the standby state. | 02-21-2013 |
20130151873 | IMAGE PROCESSING APPARATUS, CONTROL METHOD THEREFOR, AND COMPUTER-READABLE STORAGE MEDIUM - When an image processing apparatus according to this invention accepts a shutdown instruction, and completes execution of shutdown processing, and switches the operation state of the power source switch to an OFF state using a driving unit of the power source switch if the shutdown instruction is accepted via an external device communicably connected to the image processing apparatus. | 06-13-2013 |
20140036292 | IMAGE FORMING APPARATUS, METHOD FOR CONTROLLING THE SAME, AND STORAGE MEDIUM - An image forming apparatus includes a main control unit including a plurality of control units, and a sub control unit configured to respond to a request from an information processing apparatus via a network in substitution for the main control unit when the main control unit is being operated in a power saving state, wherein, in a case where the sub control unit receives a request to which the sub control unit cannot perform proxy response from the information processing apparatus, the main control unit determines a number of the control units for responding to the request among the plurality of control units and returns from the power saving state to a normal state using the control units the number of which is determined. | 02-06-2014 |
20140111822 | IMAGE FORMING APPARATUS CAPABLE OF CONTROLLING POWER SUPPLIES TO RESPECTIVE PARTS THEREOF, AND CONTROL METHOD AND STORAGE MEDIUM THEREFOR - An image forming apparatus capable of appropriately controlling power supplies to respective parts thereof when the apparatus is remotely started over a network. When receiving data from an external apparatus via the network, a controller of the image forming apparatus decides power supplied object, among a plurality of power supplied objects of the image forming apparatus, to which power supply is to be started at startup of the apparatus, and controls such that power supply to the decided power supplied object is started. | 04-24-2014 |
20150062607 | IMAGE FORMING APPARATUS HAVING POWER SAVE FUNCTION, CONTROL METHOD THEREOF, AND STORAGE MEDIUM - An image forming apparatus, having an SSD as an auxiliary storage device, which is capable of preventing loss of data in the auxiliary storage device caused by lapse of a retention period in a power save state or a power off state. In a case where the auxiliary storage device is determined to be an SSD based on type information that is acquired when the image forming apparatus is activated, a predicted retention period is calculated, and is set in a part of the apparatus that operates in the power save state. The part of the apparatus that operates in the power save state causes the image forming apparatus to transit from the power save state to a normal state based on the set predicted retention period. | 03-05-2015 |
20150062613 | IMAGE FORMING APPARATUS CAPABLE OF PREVENTING DATA LEAKAGE AND CONTROL METHOD THEREFOR, AND STORAGE MEDIUM - There is provided an image forming apparatus capable of preventing leakage of data held in a nonvolatile main storage memory by a malicious program or the like even if a shutdown process was not normally performed last time. If it is judged, when the image forming apparatus is started, that the shutdown process was not normally performed last time, a whole or a partial area of the main storage memory is refreshed before starting the information forming apparatus. | 03-05-2015 |
