A medium feeding device includes: a placement unit on which a medium is placed; a pair of edge guides that is provided at the placement unit such that the edge guides are movable in a medium width direction to guide edges of the medium in the medium width direction that is a direction intersecting a medium feeding direction; feeding rollers that feed the medium placed on the placement unit; a path state detection section that detects a detection value in accordance with a state of the medium feeding path; a guide position detection section that detects positions of the edge guides; and a control section that determines whether or not the detection value detected by the path state detection section has exceeded a threshold value.

A medium transport apparatus includes a medium transport path through which a medium passes, a path state detection section configured to output a detection value corresponding to a state of the medium transport path, a control section configured to compare the detection value output by the path state detection section with a threshold value for the detection value and determine whether an abnormal condition has occurred in the medium transport path, and a storage configured to store history information including the detection value acquired in the past, in which the control section changes the threshold value based on the history information.

A printing apparatus includes an instruction unit configured to instruct a conveyance unit to convey a first sheet, and a detection unit configured to detect a size of the conveyed first sheet, the detected size being used for image processing for printing on a different sheet from the first sheet. The instruction unit is configured to instruct, before the detection unit detects the size of the first sheet, the conveyance unit to convey a sheet next to the first sheet.

According to an example, a printing apparatus may include a first output bin, a second output bin, a first light source positioned to illuminate a portion of the first output bin, a second light source positioned to illuminate a portion of the second output bin, and a controller. The controller may activate the first light source in response to a media being outputted to the first output bin and may activate the second light source in response to a media being outputted to the second output bin to direct a user to the first output bin and/or the second output bin containing a most recently printed media.

A printing apparatus includes a processor that causes a conveyance unit to convey a first sheet to print an image on the first sheet in a free size printing mode, before a user instruction for starting printing is accepted, and causes the conveyance unit to start conveying a portion of sheets of a plurality of sheets following the first sheet to print a portion of images on the portion of the sheets following the first sheet, before detection of the size of the first sheet. The processor also causes, in the free size printing mode, the conveyance unit to start conveying other sheets, of the plurality of sheets, following the portion of the sheets following the first sheet, to print other images on the other sheets, in accordance with having confirmed detection of the size of the first sheet.

An image forming apparatus include an apparatus body, a cassette, and a size detector to detect a size of a sheet stored in the cassette. An image forming unit forms an image on a sheet fed from the cassette depending on a size setting and a type setting stored in a memory. In addition, a controller executes a first rewrite process to rewrite the size setting in a memory with size information acquired as a detection result of the size detector, if the cassette in an open state is closed, a determination process to determine whether the size information used for rewriting the size setting in the first rewrite process and the type setting stored in the memory satisfy a predetermined combination condition, and a second rewrite process to rewrite the type setting in the memory with predetermined type information that satisfies the combination condition with respect to the size information used for rewriting the size setting in the first rewrite process if the combination condition is not satisfied in the determination process.

A slide rack determination system for a digital slide scanning apparatus. In an embodiment, a motor drives a slide rack at a known rate toward an engagement surface. The elapsed time until engagement may be used to detect the presence or absence of the slide rack and/or the height of the slide rack. In addition, one or more sensors may detect one or more features of the slide rack, and these feature(s) may be used to determine the presence or absence of a slide rack, whether usage of the slide rack is supported or unsupported by the digital slide scanning apparatus, the orientation of the slide rack, and/or the manufacturer and/or model of the slide rack.

Aspects of the present disclosure provide methods and apparatuses for processing a digital image of a document, for example, to determine whether the document is a long document. An exemplary method generally includes obtaining a plurality of digital images of the document, determining a type of the document, loading one or more pre-defined metrics associated with the document based on the determined type of the document, determining one or more characteristics of the document based on one or more analyses performed on the plurality of digital images of the document, comparing the one or more characteristics of the document with the one or more pre-defined metrics, and determining the document to be a long document based, at least in part, on the comparison.

An image scanning apparatus comprises a pair of regulating members that regulates a position of the document sheet stacked on a stacking unit, at least one of the regulating members being movable in a width direction; and units that detects a length in the width direction between the regulating members, and detects the width of the document sheet conveyed by a conveyance unit; wherein in a case where a difference between the detected length and the detected width of a document sheet is smaller than a threshold, a first sheet-to-sheet interval is set, and in a case where the difference between the detected length and the detected width of the document sheet is larger than the threshold, a second sheet-to-sheet interval which is larger than the first sheet-to-sheet interval is set.

An image processing apparatus including a display unit includes a processor and a memory storing instructions, when executed by the processor, causing the image processing apparatus to function as a detection unit that detects occurrence of a sheet jammed inside the image processing apparatus and a display control unit that displays a screen based on detection of the occurrence of the jammed sheet. The screen includes a first region for displaying work that a user carries out to remove jammed sheets from inside the image processing apparatus and a second region for displaying work that the user carries out after removing the jammed sheets from inside the image processing apparatus.
