摘要:
An image forming apparatus which is capable of bringing processing devices, such as sheet feed devices and post-processing devices connected respectively to the image forming apparatus, into operable states in timing optimal for carrying out an image forming job, thereby improving productivity and operation rate of the image forming apparatus as well as saving energy. A print job is analyzed to determine at least one sheet feed device and at least one post-processing device to be used in executing the print job, and states of the determined devices are checked to determine at least one of the sheet feed device and the post-processing device to be caused to start a preparatory operation in advance before the print job is executed. Power supply to the at least one of the sheet feed device and the post-processing device is turned on in timing such that the preparatory operation is completed in time for the start of execution of the print job.

摘要:
A sheet feeding apparatus provided with a fan for blowing air against sheets stacked on a sheet tray, a position detecting sensor for detecting the position of the sheets floated up by the fan, and a tray lifting and lowering mechanism for lifting and lowering the sheet tray. The tray lifting and lowering mechanism is controlled on the basis of a result of detection by the position detecting sensor.

There is provided an image forming apparatus that is capable of preventing input errors and eliminating the necessity of complicated input operations in making settings for a sheet mixing operation in which color image output sheets and black-and-white image output sheets are mixed into one group. A stacker tray stores sheets with color images formed thereon by a color MFP and is equipped with a storage device, into and from which information relating to the sheets can be written and read. A black-and-white MFP operates in response to attachment of the stacker tray to an inserter attached to the black-and-white MFP, to execute an image formation job by providing control such that the sheets with color images formed thereon stored in the stacker tray and sheets with black-and-white images formed thereon by the black-and-white MFP are mixed according to the information stored in the storage device of the stacker tray.

A control board includes a main-board and a plurality of sub-boards which control loads. The sub-boards each include a providing unit which provides a board type ID, a read unit which reads an installation location ID, and a transmission unit which transmits the board type ID and the installation location ID to the main-board. The main-board includes a communication control unit, a configuration information acquisition unit which acquires configuration information expressed by a combination of the board type ID and the installation location ID, an analysis unit which analyzes the configuration information, and a control unit which controls the sub-unit on the basis of information analyzed by the analysis unit.

An image processing apparatus includes a first determination unit for determining the direction of an input image, a second determination unit for determining if the input image is a portrait type or landscape type, and an image rotation unit for rotating the input image in correspondence with the determination results of the first and second determination units. The image rotation unit rotates one of portrait type and landscape type images to adjust the direction of the image in a predetermined direction, and rotates the other one of portrait type and landscape type images to adjust the direction of the image in a direction perpendicular to the predetermined direction.
摘要:
An image processor rotates an image in conformity with the orientation of an original, thereby enhancing user convenience. An original conveyed by an automatic conveyance device is read by an image reader and the image is stored in an image memory. A character in the stored image is subsequently recognized by a character recognition unit and the orientation of the character is discriminated. The image is rotated by an image editor in conformity with a stapling position, and the rotated image is recorded by an image recording unit. Sheets of paper on which images are recorded are stapled at the stapling position by a staple provided in a sorter.

A copier has an operating mode in which copying is performed upon closing the cover of a platen and use is made of the size of an original to copy the original. An example is a mode in which the image of an original is divided up into a plurality of blocks and the images of the respective blocks are enlarged and each is copied on a separate sheet of copy paper. In such a scenario, it is determined whether the size of the original is capable of being sensed by sensors. If it is determined that sensing is not possible, processing for inferring the shape of the original is executed. In accordance with this processing, the size and orientation of the copy paper as well as the currently prevailing copying mode are checked, then the size and orientation of the original are inferred based upon the results of the check. Even if the size of the original is cannot be sensed, therefore, it is possible to infer the size and execute copying accordingly.

A first heating device heats a recording sheet having a developer image formed thereon, and a cooling device cools the recording sheet having been heated. A second heating device heats the recording sheet having been cooled, thereby giving gloss to the image on the recording sheet. A cooling capability of the cooling device is switched over in accordance with temperature detected by a temperature sensor which is disposed in a conveying path for the recording sheet under cooling by the cooling device.
