Abstract: If the elapsed time since a sheet was stored in a sheet storage unit is less than or equal to a threshold value, control is performed such that the sheet is heated by a fixing unit before an image is transferred to the sheet, and if the elapsed time since the sheet was stored in the sheet storage unit exceeds the threshold value, control is performed such that processing for heating the sheet with the fixing unit before the image is transferred to the sheet is not performed.

Abstract: An image forming apparatus with a detachable fixing device that is capable of printing with high quality without printing wastefully. A storage unit stores identification information about a fixing device in association with an attribute of a sheet that is printable with the fixing device concerned. A control unit executes printing when the storage unit does not store an attribute of a sheet corresponding to a fixing device that is currently attached to the image forming apparatus. The control unit determines whether to execute printing according to an attribute of a sheet used in printing and an attribute of a sheet stored in the storage unit when the storage unit stores the attribute of the sheet corresponding to the fixing device that is currently attached to the image forming apparatus.

Abstract: The present invention prevents a printing result desired by a user from being unable to be printed out, due to registration of the same color name for sheets of different colors. To accomplish this, an image forming apparatus includes a reading unit that reads in a sheet; a generating unit that generates color data indicating a color of the sheet read by the reading unit; an obtaining unit that obtains a color name corresponding to the color data generated with the generating unit, by searching a color sample database, wherein color data and color names corresponding to the color data are stored in the color sample database; and a setting unit that sets a sheet feed cassette to the color name obtained by the obtaining unit.

Abstract: A determination is performed as to whether a media setting contained in settings information of an input print job is a standard media setting for which a standard medium is to be used or a custom media setting for which a custom medium different from the standard medium is to be used. Then, in a case where the media setting is determined to be a custom media setting, the media setting is converted to a setting of a medium that can be printed by another image forming apparatus, and the converted media setting is stored.

Abstract: Proposed is an image processing apparatus in which the data processing method is changed over in suitable fashion in accordance with job settings when binding is performed. To accomplish this, the image processing apparatus is such that when stored image data is processed, the output format is determined from a job ticket and processing for dividing image data is controlled in accordance with the output format determined. In accordance with the output format determined, the apparatus changes over the output timing of divided page image data.

Abstract: If reusable data is included in a record of VDP data, a compression level used in compressing page data including the reusable data is associated with the reusable data and stored together with the reusable data. If, after that, a record of VDP data including reusable data similar to the stored reusable data is generated, the page data is compressed according to the record based on the compression ratio associated with the stored reusable data.

Abstract: An encoder is adapted to be opposed to a scale provided with a plurality of marks or slits arranged in a first direction such that a distance between centers of adjacent marks or slits in the first direction assumes a first length. Each of photo detectors has a light receiving region adapted to receive light emitted from a photo emitter and transmitted by way of the marks or slits, and is operable to output a detection signal in accordance with a quantity of the light received by the light receiving region. The photo detectors are arranged in a second direction perpendicular to the first direction while being shifted in the first direction by a second length which is one-sixteenth of the first length. Each of signal generators is operable to generate an output signal based on at least the detection signal outputted from one of the photo detectors.
