An image forming apparatus includes: an image forming unit configured to form an image on each of media; a plurality of sheet feeding cassettes each configured to store the media; a media sensor which is provided on a conveyance path through which the media are fed from any of the plurality of sheet feeding cassettes to the image forming unit, and is configured to detect a type of the conveyed media; a memory configured to store, for each sheet feeding cassette, the type of media stored in each of the plurality of sheet feeding cassettes; and a controller configured to output, to a display, a selection screen for selecting a sheet feeding cassette in which media to be used in calibration of adjusting a density of the image to be formed by the image forming unit are stored.

An identification apparatus for identifying a type of a sheet obtains, by a sensor, a plurality of parameters including a parameter concerning a characteristic of the sheet, and identifies the type of the sheet based on a result of inputting the plurality of parameters obtained by the sensor to an estimation model obtained by machine learning using, as input data, parameters corresponding to the parameters which are obtained by the sensor and include a first parameter and a second parameter classified in accordance with whether a value tends to change due to a predetermined element, and also using, as supervised data, a type of a sheet if the parameters are obtained. The estimation model includes a first partial model to which the first parameter is input and the second parameter is not input, a second partial model to which the second parameter is input and the first parameter is not input, and a third partial model that outputs a result concerning the type of the sheet based on an output from the first partial model and an output from the second partial model.

An image forming apparatus includes: a sensor configured to detect first information related to a physical property value of a sheet, the sheet to have an image formed thereon; and a processor configured to: obtain second information related to a brand of the sheet; and store the first information and the second information in a memory, the first information being detected by the sensor, the second information being obtained by the processor.

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.

Disclosed is an image forming apparatus, which may execute a job including printing an image. The disclosed image forming apparatus may include: a printer; a detector that may detect a property of a printing paper sheet, the printing paper sheet being a paper sheet used by the printer in the printing; and a determinator that may, on the basis of the property detected by the detector and a situation of the job, determine conditions for executing the printing.

Included is a print permitting/forbidding control unit configured to decide actual permitting/forbidding regarding printing regarding each of sheet feed trays, based on any one of, or a combination of any two or more of, settings of permitting/forbidding printing with regard to each sheet feed tray, setting's of permitting/forbidding printing with regard to each sheet size, and settings of permitting/forbidding printing with regard to each sheet type. At least part of settings used by the print permitting/forbidding control unit to decide actual permitting/forbidding regarding printing, out of the settings of permitting/forbidding printing with regard to each sheet feed tray, settings of permitting/forbidding printing with regard to each sheet size, and settings of permitting/forbidding printing with regard to each sheet type, can be made to differ for each user.

An image forming apparatus 10a includes (i) an image input apparatus 1, (ii) a control section 5a, (iii) a document detecting section 24 including a blank page detecting section and a separator sheet detecting section, and (iv) a file creating section 31 for creating a file of image data. The image input apparatus 1 has a double-side reading function. The file creating section 31 has a blank page skipping function and a separating function. The control section 5a includes a function setting section 51 for enabling the double-side reading function and the blank page skipping function when enabling the separating function.

A print control apparatus to communicate with a printing apparatus includes storage, display, setting, and selection units. The storage unit stores identification information of a plurality of sheets in association with stored adjustment values of a plurality of adjustment items. The display unit displays the stored identification information of the plurality of sheets. The setting unit sets, based on a user instruction, the adjustment values of the stored adjustment items. The selection unit selects, based on a user instruction, identification information of one sheet from among the identification information of the plurality of sheets displayed on the display unit. Based on a selection, the display unit displays, in addition to the displayed identification information of the plurality of sheets, at least one of the adjustment items of which set adjustment values are stored from among the adjustment values associated with the selected identification information of the one sheet.

A printer driver is implemented with a drawing function for each of the driver-executable drawing processes. The drawing function includes a first drawing function corresponding to a first drawing process. The printer driver causes the controller to receive an execution instruction of the driver-executable drawing process from the operating system together with setting information of the driver-executable drawing process. The first drawing function causes the controller to execute the first drawing process when the execution instruction to instruct execution of the first drawing process is received and a value of the setting information as received is a first value, while transmit a non-execution information indicating that the first drawing process is not executed to the operating system without executing the first drawing process when the execution instruction to instruct execution of the first drawing process is received and the value of the received setting information is not the first value.
