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 information processing apparatus includes a sensor that detects a property of a specific sheet, and a processor configured to output information about a sheet that satisfies a set condition regarding a relationship with the property detected by the sensor. The sensor includes at least an infrared sensor that detects the property by emitting an infrared ray to a sheet or an electric sensor that detects the property on the basis of an electrical resistance.

An image reading apparatus includes an image sensor to read a document, a sensor to detect whether the document is loaded on the image reading apparatus, and a processor to, when the sensor detects the document is loaded on the image reading apparatus, and before a scan instruction is input to the image reading apparatus, control the image sensor to execute a pre-scan job with respect to the loaded document using a default set value.

An image reading apparatus includes a medium mounting portion configured to mount a medium; a feeding means configured to feed a medium from the medium mounting portion; at least one edge guide each configured to regulate a corresponding one of at least one medium width direction edge of the medium having been mounted on the medium mounting portion; a reading means configured to read the medium and disposed on a further downstream side than the at least one edge guide in the medium feeding direction; and at least one medium detection means configured to detect the medium and disposed on a further downstream side than the at least one edge guide in the medium feeding direction and further outside in the medium width direction than at least one edge regulation position for the edge regulation by the at least one edge guide.

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.

An image forming apparatus includes an image forming unit, an intermediate transfer member, a transfer member, a power source, a fixing unit, a photo sensor photosensor, and a control unit configured to perform a mode to output a test chart which is formed by transferring a plurality of test toner images from the intermediate transfer member onto a plurality of sheets of the recording material, the test chart being used to adjust the transfer voltage applied to the transfer member. The control unit is configured to adjust the transfer voltage based on a detection result of the photo sensor photosensor detecting the plurality of test toner images recovered fixed on the recording material. In a case where a jam occurred during execution of the mode, the control unit is configured to resume the mode after the jam has been recovered.

An image processing device comprising a processor configured to: determine presence or absence of a face image for each of a plurality of pieces of image data read from at least one image presenting medium, and decide a relationship for the plurality of pieces of image data, based on a result of the determination. The relationship is a front and back of the image presenting medium or a page order, and the processor is further configured to: decides that image data including a face image is on a front side of the image presenting medium or on a page before image data not including a face image.

Methods and system are disclosed for a double-feed detector with neural network classifier. These includes accepting pages of a print-based media substrate into a scanning device with a paper feed device, back-illuminating the pages using a light source, capturing a page image of back-illuminated pages using an image capture device, detecting noise patterns exhibited by the page image using an image processor, classifying detected noise patterns using a noise pattern classifier, and determining, using classified detected noise patterns and a neural network controller for a neural network model, whether the at least one page is a sheet stack (at least two pages stacked together and passing through the paper feed device concurrently) based on the classified detected noise patterns. On condition a sheet stack is detected, a sheet stack detected signal triggers taking an action.

An information processing apparatus performs acquiring measurement results obtained by measuring a characteristic of a recording medium a plurality of times; inputting information corresponding to a type of the recording medium; acquiring an extraction range of the type indicated by the information, among extraction ranges set to respective types of recording media for determination of a type; setting, based on the measurement results and the type, a parameter for correcting the measurement results to reduce difference between the measurement results and the extraction range; correcting, by using the parameter, measurement results obtained by measuring a characteristic of a recording medium to be recorded; and extracting a candidate type of the recording media, the measurement results, based on the corrected measurement results and the extraction range.

An image reading apparatus includes: at least one processor configured to: set reading resolutions in a first and a second directions when reading an image of a document; determine an inclination amount of the document; correct an image to reduce the inclination amount; output image data indicative of an corrected image; and obtain information relating to a first direction length of the document. In a case where the first direction length of the document is less than a predetermined length and the processor outputs the image data indicative of the corrected image, whose resolution in the first direction is a first resolution and resolution in the second direction is a second resolution lower than the first resolution, the processor sets the reading resolution in the second direction to a third resolution higher than the second resolution.
