An image forming apparatus, in which an image forming method is performed, includes an image forming device to form an image on a recording medium, a reading device to scan the recording medium having a mark and generate a scanned image, and circuitry to calculate a correction value to adjust a position of the image to be formed on the recording medium, based on the scanned image. The circuitry calculates the correction value to adjust a position of an image to be formed on a second face of the recording medium based on a first scanned image generated from a first face of the recording medium, within a period from when the first scanned image is generated from the first face to when the image starts to be formed on the second face.

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.

Systems and methods are provided for document handling. Non-vision detection systems may be capable of detecting the dimensions, orientation, and/or position of a single sheet, or multiple stacked sheets. A document scanning arrangement may be capable of double sided scanning for sheets with various characteristics. The systems and methods provided may accommodate high throughput and rapid digitization of various types of documents, at a high quality.

In an example, a print system include a component device that is operation in a number of state, a density engine, and a component engine. An example density engine identifies a plane region of a plane where print fluid is to be printed based on data of a print job and determines a density classifier for the plane based on a location of the plane region on the plane. An example component engine causes an adjustment of a component attribute of the component device based on the density classifier.

An election voting system is provided. The election voting system includes a printer for accepting printer medium. In one embodiment, the printer medium may be a paper printer medium. The printer medium includes mark(s) positioned on the printer medium that may be utilized to determine whether the printer medium is inserted into the printer in the proper orientation. The election voting system may include a sensor that identifies the presence of the mark. Two marks are positioned so that the orientation of the paper (right side up versus upside down) can be determined. In addition, in one embodiment, the marks are positioned so that even if the printer medium is rotated 180 degrees, orientation as to which side is up may be detected.

In a displacement sensor, an illumination optical system, which converts laser light emitted from an emission unit into first converging light, and irradiates with the first converging light a detection space through which a target moves. An imaging optical system converts laser light reflected from the target into second converging light, and irradiates with the second converging light a light-receiving surface of a detection unit. The image of the emission unit into which the illumination optical system focuses the first converging light is displaced along the optical axis of the imaging optical system by a temperature change of the illumination optical system. The range in which the image is displaced is limited to be located either anterior to the front principal point of the imaging optical system, or posterior to the rear principal point of the imaging optical system.

A printer for printing on a long sheet includes a print data divider and a verification processor. The print data divider outputs a plurality of segments of divided print data divided at the boundary of areas from standard print data containing print contents in each of the areas obtained by dividing a standard sheet into a plurality of the areas. The verification processor compares the size of the long sheet with the size of the area included in the standard sheet and rotates the divided print data if it is determined from a result of the comparison that the rotation is necessary.

An information processing apparatus includes a processor configured to: obtain information about a form of placement of a document placed on a document stage of an apparatus that performs reading of the document by capturing an image of the document stage on which the document is placed; and change a process that is performed in association with reading of the document, in accordance with the form of placement of the document on the document stage.

There is provided an image forming apparatus capable of preventing deterioration in accuracy of image position adjustment due to erroneous detection of a marker.

An image scanning apparatus includes a distance detector configured to output a detection signal having a value corresponding to a distance in a main scanning direction from a particular position to a side end of a document sheet being conveyed, and a controller configured to store a first position of the document sheet in a conveyance direction when the distance detector outputs a detection signal having a first value corresponding to a first particular distance, store a second position of the document sheet in the conveyance direction when the distance detector outputs a detection signal having a second value corresponding to a second particular distance, and calculate a skew angle of the document sheet based on the first position and the second position.
