An image forming apparatus includes a first detector, a second detector, and a determination section. The first detect detects a first skew angle of a sheet. The second detector is located downstream of the first detector and detects a second skew angle of the sheet. The determination section determines whether or not to stop conveyance of the sheet based on the first skew angle and the second skew angle.

An image forming apparatus includes an image forming section, a case section, a conveyance section, a controller, an acquiring section, and storage. The controller controls the image forming section and the conveyance section according to mechanical settings information corresponding to a type of the sheet. The acquiring section acquires an identification image for identifying the type of the sheet. The storage stores therein mechanical-settings-information candidates and registered images associated with the mechanical-settings-information candidates. The controller determines whether or not a matching image exists when a sheet is loaded in the case section. Here, the matching image is a registered image matching the identification image of the registered images. The controller adjusts mechanical settings information based on a mechanical-settings-information candidate associated with the matching image of the mechanical-settings-information candidates when determining that the matching image exists.

An image forming apparatus that forms an image on a recording medium, including: a detector that detects a physical property of the recording medium and obtains a detection value; and a hardware processor that controls an operation of the image forming apparatus based on: the detection value detected by the detector, and at least one of: first information that relates to the recording medium and does not include the detection value or a physical property value calculated based on the detection value, and second information that does not relate to the recording medium and is acquired from outside of the image forming apparatus.

A system comprising a multifunctional peripheral device in which the multifunctional peripheral device comprises a processor and a display device, in which the processor detects signature lines in an electronic document, and in which the display device of the multifunctional peripheral device displays the detected signature lines one at a time.

An image processing apparatus includes an scanner, a print engine, and a controller configured to control the scanner to scan images of one or more document sheets, thereby generating scanned image data, generate print data based on the scanned image data, control the print engine to print, on sheets, the images based on the print data, generate first log image data through reducing a data size of image data associated with the scanned image data, determine whether the first log image data includes a particular type of page, and when determining that the first log image data includes the particular type of page, generate second log image data having higher image quality than the first log image data.

A machine learning applies page parameters of a complex document file to transform the complex document file into pre-press operator action predictions for the complex document file. Prompts are generated on an operator console for a pre-press operator to confirm the pre-press operator action predictions, and to apply responses to the prompts to enhance the classification model and to control a printer.

An image forming device includes: an image former that forms an image of original data included in a job on paper; a reader that reads the image formed on the paper; and a hardware processor, wherein the hardware processor performs control of determining whether the paper is paper on which the image of the original data is formed, control of allowing the image former to form an image for adjustment on the paper in a case where the paper is used for a purpose other than a purpose of forming the image of the original data, and control of allowing the reader to read the image for adjustment and adjusting the image former based on read data of the image for adjustment.

An information processing apparatus is configured to control an operation to determine a type of a printing medium to be printed by a printing unit, determine a type of printing medium indicated by information input by an input unit as the type of the printing medium to be printed, and be capable of executing a measurement mode and a designation mode. In the measurement mode, the type of the printing medium to be printed is determined by using a measurement result and a reference characteristic values set in advance. In the designation mode, the type of the printing medium to be printed is determined without using the measurement result. The information processing apparatus is configured to, even in the designation mode, change the reference characteristic value set in advance for the type of printing medium indicated by the information input by the input unit based on the measurement result.

An image forming apparatus determines a correction value for correcting an output value of each of first spectral sensors, based on a measurement result of a first measurement image acquired by the first spectral sensors and a measurement result of the first measurement image acquired by a second spectral sensor while the second spectral sensor is being moved, corrects, using the determined correction value, an output value output from each of the plurality of first spectral sensors by measuring a second measurement image, and modifies an image forming condition based on the corrected output value.

A control method in a printing apparatus includes printing, by a printing unit, an adjustment image for adjusting a printing position on a sheet, conveying, by a conveying unit, the sheet on which the adjustment image is printed, reading, by a reading unit, an image to generate image data, the reading unit being executable to perform reading by a first reading method for reading an image of a sheet without conveying the sheet or a second reading method for reading the image of the sheet while conveying the sheet, and determining, based on that a type of the sheet on which the adjustment image is to be printed is a specific type, to read the adjustment image by the first reading method.
