An information processing apparatus, to communicate with an image forming apparatus having a predetermined sheet feeding unit, includes a selection unit and a setting unit. The selection unit selects one storage method at least from among a first and second sheet information storage method. The setting unit executes a setting, based on the selected one storage method, for the predetermined sheet feeding unit. In the first sheet information storage method and after the sheet information is set for the predetermined sheet feeding unit, the setting of the sheet information is not cancelled when an absence of a sheet on the predetermined sheet feeding unit is detected. In the second sheet information storage method and after the sheet information is set for the predetermined sheet feeding unit, the setting of the sheet information is cancelled when an absence of a sheet on the predetermined sheet feeding unit is detected.

A printing apparatus having an insert-sheet inserting function includes a plurality of sheet-feeding ports, a printing mechanism that performs printing on paper fed from each sheet-feeding port, and a controller that controls the printing mechanism. In a case where no insert-sheets are present in a sheet-feeding port for insert-sheets when the printing mechanism feeds the insert-sheets from the sheet-feeding port for insert-sheets, the controller selects another sheet-feeding port different from the sheet-feeding port for insert-sheets as a new sheet-feeding port for insert-sheets on the basis of a paper specification of paper used for printing data to be printed and a sheet-feeding port setting.

A spectral characteristic obtaining apparatus includes a color information obtaining unit including a plurality of spectral sensors aligned in an array direction, the spectral sensors being configured to receive light reflected from an object so as to obtain first color information of the object; a spectral characteristic calculating unit configured to estimate a spectral characteristic of the object based on the first color information by using a preset transformation matrix; a calibration color index configured to include a region of a color with a known spectral characteristic; and a transformation matrix calibrating unit configured to calibrate the transformation matrix by using second color information obtained from the calibration color index, wherein the spectral sensors are configured to obtain the second color information from the same region included in the calibration color index, while relative positions thereof with respect to the calibration color index are changed at a time of calibration.

Systems and methods are provided for document handling. Non-vision detection systems may be capable of detecting the dimensions, orientation, and/or position of a single sheet, or multiple stacked sheets. A document scanning arrangement may be capable of double sided scanning for sheets with various characteristics. The systems and methods provided may accommodate high throughput and rapid digitization of various types of documents, at a high quality.

An image forming system includes: an information processing apparatus configured to output information related to a print job to form an image on a recording medium, the image forming apparatus being configured to be operable in a plurality of power modes including a first normal power mode in which the information is output and a first power saving mode in which power consumption is less than the first normal power mode; and an image forming apparatus having: an image forming unit configured to form an image on the recording medium based on the print job output from the image processing apparatus, and an operation unit to be operated by a user to instruct to form the image by the image forming unit.

An information processing apparatus includes a processor configured in which an area to be processed in a document is specified using a position of a marker placed on a surface of the document. When the marker is placed, the processor uses a placement position of the marker to specify the area to be processed and register area information indicating the area to be processed. When the marker is not placed and the area information is registered, the processor executes predetermined processing with respect to the area to be processed that is indicated by the area information. When the marker is not placed and the area information is not registered, if the area information is registered after a predetermined area of the document is registered as a target, the processor specifies the area to be processed as indicated by the area information as the area to be targeted by the processing.

The image forming apparatus includes a processor configured to perform a print process on print media of plural pages, based on print data for the plural pages, acquire reprinted pages by performing a reprint process on separate print media for defective pages for which a result of the print process is defective, with print settings determined according to an arrangement posture of excellent pages, for which a result of the print process is excellent, on a reuse tray, and output the excellent pages transported from the reuse tray and the reprinted pages together.

A post-processing apparatus acquires a status of an image forming apparatus and sheet information of sheet feeders in the image forming apparatus, and when determining that sheets used in a print job that the image forming apparatus is instructed to perform need to be fed on the basis of the acquired status and sheet information, transmits information on the sheet feeding together with an instruction to perform the print job to the image forming apparatus when instructing the image forming apparatus to perform the print job.

An image forming apparatus includes a mounting surface provided on a main body and on which paper is placed; a person detection section provided in the main body; a processor configured to control return from a sleep state of the main body, based on the detection of a person by the person detection section, and perform control such that in a case where there is no paper on the mounting surface when transition to the sleep state, a nearby person approaching the main body is included in a detection target of the person detection section, and a passerby passing near the main body is not included in the detection target, in the sleep state, and in a case where there is a paper on the mounting surface when the transition, the nearby person and the passerby are included in the detection target, in the sleep state; and a notification section that notifies of paper remaining in a case where there is a paper on the mounting surface after the return.

An image forming apparatus includes: a plurality of paper feed trays that feed accommodated sheets of paper; a detector that detects absence of paper in the paper feed trays; an image former that forms an image on a sheet of paper fed from one of the paper feed trays based on a print job; and a hardware processor that identifies a job attribute of the print job issued, selects a first tray switching condition or a second tray switching condition that is more lenient than the first tray switching condition in accordance with the job attribute identified, and in response to the detector detecting absence of paper in the paper feed tray in use during execution of the print job, switches to another paper feed tray that satisfies the tray switching condition selected.
