For a plurality of types of print media, a pre-trained model is prepared, the pre-trained model being generated by machine learning based on spectroscopic information of an unprinted area on the print medium and an identifier indicating the type of the print medium and using the identifier as a trainer. The spectroscopic information of the unprinted area on the print medium to print on is acquired. The acquired spectroscopic information is applied to the pre-trained model. Using a result thereof, auxiliary information about the type of the print medium is outputted. A specification of the type of the print medium using the outputted auxiliary information is accepted. When the type of the print medium is thus specified, printing is performed using a print condition suitable for the print medium.

An image forming apparatus includes a processor configured to: receive paper information on a type of paper on which an image is formed; acquire assist information about assistance to supply the paper by supplying gas to the paper and adjustment information about positioning of the paper after assistance to supply the paper is performed, the assist information and the adjustment information corresponding to the received paper information and relating to transport of the paper; and perform control for storing the paper information, the assist information, and the adjustment information in association with one another into a memory.

An image formation system includes an image forming apparatus and an inserter. The image forming apparatus includes an image forming device, a conveyance device, and a control device. The control device functions as a controller and an executor. The controller allows the inserter to insert an interleaving paper between sheets of printed material at an insertion start timing specified by a print job. When the plurality of calibrations include a second calibration capable of being completed within an interleaving paper insertion time required to insert the interleaving paper or a third calibration capable of being completed within a total time of the interleaving paper insertion time and a predetermined additional time, the executor executes the second calibration or the third calibration in time with the insertion start timing.

An image forming apparatus includes a processor configured to: receive paper information on a type of paper on which an image is formed; acquire assist information about assistance to supply the paper by supplying gas to the paper and adjustment information about positioning of the paper after assistance to supply the paper is performed, the assist information and the adjustment information corresponding to the received paper information and relating to transport of the paper; and perform control for storing the paper information, the assist information, and the adjustment information in association with one another into a memory.

Printers capable of determining a media type of a media and associated methods are provided. An example method includes scanning a media with a verifier associated with the printer to generate at least two consecutive windows of the media. The example method further includes determining a vertical length of a captured image based on a comparison of image characteristic values captured in the at least two consecutive windows. The example method further includes determining a media characteristic associated with the media based at least on the captured image and the vertical length and one or more stored media profiles. The example method further includes calibrating the printer based on the media characteristic.

An image reading apparatus including: a conveyor that conveys a sheet on which an image is formed by an image forming apparatus; a reader that reads the sheet conveyed by the conveyor, by using a contact image sensor; and a first hardware processor that extracts an edge of the sheet by analyzing a read image by the reader, calculates a blur amount of the edge based on the extracted edge, and calculates a curl amount of the sheet based on the calculated blur amount.

The present disclosure provides an image forming apparatus capable of improving usability in a configuration where information related to sheet size is detected automatically, and a control method thereof. A control unit is configured to execute a determination process if the control unit acquires a detection result of a size of a sheet supported on a sheet support portion by a size detection unit in a state where a first information related to a size of a sheet and a second information related to a type of a sheet that satisfy a predetermined combination condition are stored in the storage portion. The control unit determines in the determination process whether the detection result of the size of the sheet satisfies the combination condition with respect to the second information stored in the storage portion, and changes a successive procedure depending on a result of the determination process.

A control apparatus includes a storing unit, a determining unit, a first notification unit, a selection unit, and a second notification unit. The storing unit stores attribute information of sheets to be stored in sheet holding units. The determining unit determines whether attribute information of sheets to be used by a job corresponds to the stored sheet attribute information. The first notification unit notifies, in a case where the determining unit determines that the attribute information does not correspond, a user that the attribute information does not correspond to the sheet attribute information. The selection unit selects the stored sheet attribute information to change the attribute information of sheets to be used by the job. The second notification unit notifies, in accordance with selection of the sheet attribute information, the user that the attribute information of sheets to be used by the job corresponds to the stored sheet attribute information.

In a case where the printing of a plurality of copies based on an original image is to be executed by causing a feeding stage which is set for each of the plurality of copies to perform feeding, a feed operation is controlled so as to stop feeding from a feeding stage which serves as a feed target when a sheet attribute designated in a job and a sheet attribute set in the feeding stage are different from each other.

An image forming method includes: determining a number of copies; obtaining an original image including an object of a paper piece; detecting a paper piece size, the paper piece size being a size of the object of the paper piece included in the original image; clipping the object of the paper piece having the paper piece size from the original image to generate a paper piece image; and arranging the paper piece images of the number of copies on a printable area of one or more pages based on a printable size and the paper piece size and add a guide image to generate a reconfigured image, the printable size being a size of the printable area, the guide image being an image of a guide for dividing the paper piece images of the number of copies.
