A system and method for aligning documents for scanning includes a multifunction peripheral with a controller having a processor and associated memory. The controller issues instructions controlling operation of a scanner. A tangible document is placed on a surface of a scanner platen, and a sensor determines its location relative to the platen. An optimal position of the document relative to the platen is determined. The processor then generates a graphical rendering on an associated display indicative of a directed repositioning of the document on the platen in accordance with a determined optimal position of the document relative to the platen.

A position detecting device includes an image sensor and circuitry. The image sensor is configured to read reflected light of light emitted from a light source onto a medium to be read. The circuitry is configured to perform black correction processing on an output signal of the image sensor using black correction data of the image sensor and detect a position of the medium from the output signal after the black correction processing.

An image reading device can perform fixed-reading processing where image data is read by a fixed-document method and conveyed-reading processing where image data is read by a sheet-through method while a reading module is kept staying at any of a plurality of image reading positions including a reference reading position. A control portion, when a reference second adjustment value for the reference reading position used for shading correction in the conveyed-reading processing is acquired, calculates a second adjustment values for a plurality of image reading positions based on the reference second adjustment value, and when the reference second adjustment value is not acquired and a first adjustment value used for shading correction in the fixed-reading processing is acquired, calculates the second adjustment values for the plurality of image reading positions based on the first adjustment value.

A system and method for aligning documents for scanning includes a multifunction peripheral with an intelligent controller having a processor and associated memory. The controller issues instructions controlling operation of a scanner. A tangible document is placed on a surface of a scanner platen, and a sensor determines its location relative to the platen. An optimal position of the document relative to the platen is determined. The processor then generates a graphical rendering on an associated display indicative of a directed repositioning of the document on the platen in accordance with a determined optimal position of the document relative to the platen.

A position detecting device includes circuitry. The circuitry is configured to control a reading device to detect, as a first detection result, an outer shape of a processing subject and a position of an image pattern on the processing subject; control the reading device to detect, as a second detection result, a mark arranged on a position reference member, the mark corresponding to a predetermined position in the reading device; and detect a first correction value of the reading device and a second correction value of the reading device corrected by the first correction value on basis of the second detection result and reflect the first correction value and the second correction value to the first detection result to correct a processing position in the processing subject.

An imaging device includes: an imaging unit that divides an object to be imaged into multiple areas, and captures multiple divided images; a correcting unit that corrects the multiple divided images captured by the imaging unit; and a generating unit that generates one composite image by compositing the multiple divided images after being corrected by the correcting unit.

An image forming apparatus includes a scanner configured to read an image of a document and generate image data of the image according to a reading mode, a storage device configured to store the image data and the reading mode used when reading the image of the document, and a processor. The processor generates a combined image that includes the image of the document and a reading direction image that indicates a reading direction of the scanner and has a shape indicating the reading mode, and store data of the combined image in the storage device. The processor determines a position of the reading direction image in the combined image and a size of the reading direction image in the combined image, based on a reading resolution of the scanner and a resolution of the image data stored in the storage device.

Provided are systems and methods for identifying, isolating, and/or aligning sheets. An identification system can facilitate accurate identification of a sheet by (i) vacating one or more components of the system that are not the sheet from a zone of detection, and/or (ii) determining a reference axis of the sheet. An isolation system can facilitate accurate isolation of a sheet by (i) providing targeted air flow, and/or (ii) introducing a wave into the sheet. Identification systems and/or isolation systems described herein may facilitate isolation of sheets that were previously fastened together by one or more fasteners. An alignment system can facilitate accurate alignment of a first sheet at an upstream location relative to a second sheet at a downstream location via machine learning.

An image forming apparatus includes: a transfer section that transfers an image to a sheet; a sheet conveyance member that is provided on an upstream of the transfer section in a sheet conveyance direction and that conveys the sheet; and a hardware processor that controls the sheet conveyance member to displace the sheet, wherein a preset value defining a displacement condition of the sheet conveyance member for providing a correct position of the image on the sheet is set.

An image forming apparatus includes a scanner, a printer for printing an image based on an image read by the scanner, a memory storing a setting value for adjusting positioning of an image to be printed by the printer on a sheet of a sheet size, and sheet size information specifying the sheet size corresponding to the setting value, a display, and a processor. The processor is configured to control the display to display an operation guidance screen for readjustment of the setting value, control the scanner to perform a scanning of a sheet provided in accordance with the operation guidance screen, acquire, as a readjustment sheet size, a size of the provided sheet based on a scanning result of the scanning, and update the setting value stored in the memory based on a difference between the sheet size indicated by the sheet size information and the readjustment sheet size.
