An image forming apparatus includes a scanner, a printer configured to print an image based on an image read by the scanner, a memory, and a processor. The memory stores a setting value for adjusting positioning of an image to be printed by the printer on a first sheet of a first sheet size, and sheet size information specifying the first sheet size corresponding to the setting value. The processor is configured to modify the setting value stored in the memory based on sheet information related to a second sheet to be used for printing, the second sheet having a second sheet size different from the first sheet size.

A control device includes a controller that determines, based on physical property information corresponding to physical property of a recording sheet and read information on an image evaluated as abnormal through reading of an image on the recording sheet by a reading section on a recording sheet conveyance path, a process condition under which an image forming section performs image forming on the recording sheet.

An information processing apparatus includes a processor configured to: acquire a read image resulting from reading a recording medium where a diagnostic image to be used to diagnose an image forming apparatus is formed; acquire, from the read image, an image read portion of the recording medium from which the diagnostic image is read and one specific portion of a non-formation read portion, the non-formation read portion resulting from reading a non-formation portion of the recording medium where the diagnostic image is not formed; and output the image read portion and the one specific portion.

Anon-transitory computer-readable storage medium stores computer-readable instructions executable by a processor of an information processing device. The instructions support a general-purpose printing program incorporated in an operating system of the information processing device. The instructions, when executed by the processor, cause the information processing device to obtain, from a printer, main body information about sheet characteristics for each feed tray of the printer, obtain print settings from the general-purpose printing program, generate, based on the main body information, notification data including sheet information indicating the sheet characteristics for a feed tray set in the print settings, and provide the notification data to the general-purpose printing program, thereby enabling the notification data to be displayed on the print setting screen.

In some examples, a fuser for a printing device includes a memory device comprising corrective data corresponding to a reference color table for the printing device that is able to operate in a plurality of different modes, the corrective data comprising quantized coefficients derived from a compression of a difference color table including a plurality of difference nodes in which each difference node represents a value that is to be combined with a corresponding node of the reference color table, the quantized coefficients useable to produce a reconstructed difference table. The corrective data including residue values to combine with the reconstructed difference table to produce a customized color table for a selected mode of the plurality of different modes.

Provided are an image forming apparatus for outputting a plurality of images having different sizes according to a method pre-set by a user without interrupting a current printing operation when the plurality of images having different sizes are obtained and a method of operating the image forming apparatus.

An image processing apparatus includes an acquisition unit, an identification unit, and a generation unit. The acquisition unit acquires image data generated by reading an image on an original. The identification unit identifies a predetermined size of an original, the predetermined size being different from a size of the original. The generation unit adds image data of a different image to the acquired image data, without changing a size of the image in the acquired image data, to generate image data corresponding to the predetermined size of the original.

This disclosure is directed to improving the precision of color reproducibility in a whole image region of any product provided with a base layer(s) regardless of any form of the base layer(s). The RIP (Raster Image Processor) device includes a color conversion processor that applies a color conversion process adapted for presence or absence of a base layer and for a base color to content data representing part or all of details of an image layer at a respective one of positions in an image region indicated by the image layer, and an image layer data generator that generates image layer data representing ejection-related information of ink droplets of a plurality of colors using the content data that has been subjected to the color conversion process.

An image reading apparatus includes a platen, a copyholder configured to rotate around a rotary axis, and a reader configured to read a reading surface pressed against the copyholder, of a document placed on the platen. The reader is supported by the copyholder to be able to move in a direction not parallel to the rotary axis.
