Abstract: An image forming apparatus includes a plurality of devices configured to perform different job processing, a control unit configured to control job processing performed by each device, a reception unit configured to receive an instruction for causing the control unit to shift to a state where the job processing is capable of being performed, and a power control unit configured to, when the control unit is shifted to a stand-by state in response to receiving the instruction, supply a power to a device specified based on a job processing function corresponding to an initial screen to be displayed.

Abstract: A technique for reducing the number of times of power state transition by appropriately executing, at an accelerated time point, processing of an event that needs to be performed in a current power state before transition to another power state is provided. A data processing apparatus according to one aspect of the present invention determines, when transition of a power state from a current power state occurs, whether or not there is an event that is to be scheduled to be performed within a predetermined time in the same power state, and executes the scheduled event at an accelerated time point if it is scheduled to be processed within the predetermined time in the same power state.

Abstract: An image forming apparatus that is capable of coping with both a high power saving effect and a quick response. A reading unit reads an image of an original. A printing unit prints out image data. A control unit controls units including the reading unit and the printing unit. A detection unit detects an original placed in the reading unit. A power control unit restores the control unit and the reading unit from a sleep state when the detection unit detects an original, and further restores the printing unit from the sleep state before receiving a job when a sheet of the same size as the original concerned is stored.

Abstract: Provided is an information processing apparatus and method of controlling same in which, when data transfer is performed among a plurality of control circuits, which control circuit is used to execute data transfer is controlled appropriately based on the transfer conditions of data transfer. To accomplish this, the apparatus has first and second control circuits, a request for data transfer performed between the first and second control circuits is acquired, the transfer conditions of the acquired data transfer are analyzed and which of the first and second control circuits is to execute the data transfer is selected.

Abstract: An information processing apparatus capable of recovering the apparatus from a state in which software operation is abnormal to a state in which the same is normal. The information processing apparatus is provided with a CPU for receiving an instruction for turning off power of the information processing apparatus. Upon receipt of the instruction, the CPU determines whether or not it is necessary to turn off the power of the information processing apparatus. When it is necessary to turn off the power of the information processing apparatus, the CPU controls the information processing apparatus such that the power thereof is turned off, whereas when it is unnecessary to turn off the power of the information processing apparatus, the CPU controls the information processing apparatus such that the power thereof is not turned off.

Abstract: The present invention provides an image forming apparatus that includes a first system and a second system, wherein the permission/prohibition of access to a storage unit provided in the first system is controlled appropriately based on a signal transmitted from the second system, and a control method thereof. To accomplish this, the image forming apparatus of the present invention includes the first system and the second system, and permits access to the storage unit only when executing a program that includes a predetermined process to activate the apparatus using an external storage apparatus.

Abstract: This invention provides an information processing apparatus that reduces user operations and also the processing load on an image forming apparatus upon instructing the image forming apparatus to execute pull-print processing, and a control method thereof. To accomplish this, the information processing apparatus is connected to an image forming apparatus that stores a plurality of files to be image formed. If the image forming apparatus can interpret the format of the file, the information processing apparatus issues an image forming instruction to the image forming apparatus by designating the storage location of that file. On the other hand, if the image forming apparatus cannot interpret the format of the file, the information processing apparatus transmits data obtained by converting the file into an interpretable format, and issues an image forming instruction of that data to the image forming apparatus.
