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 apparatus includes an output unit configured to output a printed material of a verification image in a case where a condition is satisfied, an obtainment unit configured to obtain a verification result based on a comparison between a read image of the printed material of the verification image and a correct answer image, and a control unit configured to control printing based on the verification result.

A photoelectric conversion element includes a first pixel array including first light-receiving sections arranged in a direction and a second pixel array including second light-receiving sections arranged in the direction. Each of the first light-receiving sections includes a first pixel configured to receive at least light having a first wavelength inside a visible spectrum and a first pixel circuit configured to transmit a signal from the first pixel to a subsequent stage. Each of the second light-receiving sections includes a second pixel configured to receive at least light having a second wavelength outside the visible spectrum and a second pixel circuit configured to transmit a signal from the second pixel to the subsequent stage. The second pixel circuit is provided in a vicinity of the second pixel.

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.

A printing system that performs printing includes a printing apparatus in which at least a part thereof is configured by a unit part which is a replaceable function component. The printing apparatus is controlled using a command group including a printer control command which is a command for controlling the printing apparatus and a unit inspection command which is a command used for an inspection of the unit part. At least a part of the printing apparatus is configured by a plurality of unit parts having different functions. The plurality of unit parts are configured to be inspected using the unit inspection command.

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 forming apparatus is configured to obtain user designation information indicating a type of a sheet onto which an image is to be formed, control an image forming unit to form the image on the sheet in a case where a condition for permitting image formation is satisfied, even when a detecting result from a sensor indicates a type different from the type indicated by the user designation information, and control the image forming unit to skip forming the image on the sheet in a case where the condition is not satisfied, in a case where the detecting result from the sensor indicates a type different from the type indicated by the user designation information.

A control device includes a processor and a first storage portion. The processor executes a control process based on data stored in a main memory. The first storage portion stores a first memory image related to the main memory after a process of starting-up an operating system by the processor is completed. The control device loads the first memory image into the main memory if the operating system is started up.

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.
