Abstract: An image forming apparatus activates target devices including connected devices and internal devices, and executes a requested process. The image forming apparatus includes an acquiring unit configured to acquire information pertaining to the connected devices, information pertaining to a startup method of the image forming apparatus, and information pertaining to maximum usable power of a power supply unit of the image forming apparatus; a specifying unit configured to verify what the target devices are and specify a corresponding activation pattern based on the information acquired by the acquiring unit, wherein the corresponding activation pattern is specified among plural activation patterns that have been set in advance, each of the plural activation patterns defining activation timings of the target devices; and an activation control unit configured to control activation of the target devices in accordance with the corresponding activation pattern specified by the specifying unit.

Abstract: When multiple-size double-side printing in an APS mode has been selected, a system CPU first reads an original which corresponds to a second side of a paper sheet, prints data of the original on the second side of the paper sheet having the same size as the original, and stacks the paper sheet on an automatic double-side unit. Subsequently, the system CPU reads an original which corresponds to a first side of the paper sheet and prints data of the original on the first side of the paper sheet stacked on the automatic double-side unit, thus completing the double-side printing. However, where the size of an original corresponding to a second side differs from the size of an original corresponding to a first side, single-side printing is effected. The original corresponding to the first side is read and data thereof is printed on a paper sheet having the same size as the original and the sheet is discharged (single-side printing).

Abstract: When an operation mode of an image forming apparatus returns from an energy-saving mode to a regular operation mode, a CPU of a main system outputs a power control signal set to High, and determines the necessariness of information display on an LCD of an operation unit control system to output a starting mode selection signal set to High when the result of the determination is positive. A CPU of the operation unit control system detects the state of a power control signal, and detects mode return from the energy-saving mode depending on the result of the above detection. The CPU of the operation unit control system also detects the state of a starting mode selection signal, and determines the necessariness of information display on the LCD depending on the result of the detection to carry out a display process depending on the result of the determination.

Abstract: An image forming apparatus including a controller configured to control each unit of the image forming apparatus, and an engine to which a startup instruction is sent from the controller and a plurality of peripheral devices is connected in series. Power is supplied to the controller and the engine separately, and further supplied to the plurality of peripheral devices from the engine. The engine independently sends startup instructions to the plurality of peripheral devices.

Abstract: A startup controller includes an engine controller, a controller, and a return signal controller. The engine controller is connected to a device that performs mechanical operation, and controls the mechanical operation of the device. The controller establishes communication with the engine controller, and controls process related to the device through the communication. The return signal controller is connected to the engine controller, and sends first information related to a startup state of the device to the engine controller. The engine controller controls the startup of the device based on the first information received from the return signal controller before the controller establishes the communication.

Abstract: Where double-side printing is effected on a single copying paper sheet to produce images of two originals thereon, the directions of images on the originals can be considered. Even where the directions of images on originals, which can be positioned only horizontally due to the structure of a copying machine, are the portrait and landscape, the printing according to the directions of images can be made. Even in the case of originals which can be positioned vertically and horizontally, the originals can be set (for input) in conformity to the direction of paper sheets set in the machine and the printing with regulated directions of images can be made by setting the directions of images. More specifically, even where a vertically positioned original is set horizontal for printing, the same printing result as in the case where it is set vertical can be obtained and the performance of the copying machine is enhanced.

Abstract: A file transfer system includes a file management server, a file transmitting terminal, and a file receiving terminal connected each other via a network. The file transmitting terminal transmits to the file management server a file and an authorization condition for accessing the file. The file management server stores the file and the authorization condition relating each other. The file receiving terminal transmits to the file management server a request for transferring the file. The file management server, in response to the request, determines whether the authorization condition is satisfied, and if the authorization condition is satisfied, transfers the file to the file receiving terminal. Accordingly, a user can safely receive the file via the network even if the user does not have an information apparatus having memory capacity large enough to receive the file.
