An image forming apparatus includes an image reading device; an image forming device including a photoconductor, a charger, an exposure device including a light-emitting element, a memory to store a first correction value for correction a light emission amount of the light-emitting element, and a driver to drive the light-emitting element, a developing device, a transfer device, and a fixing device. The image forming apparatus further includes a processor to calculate a second correction value for correcting the light emission amount, based on density data of image data of a predetermined pattern on a recording medium; calculate a third correction value for correcting the light emission amount, based on the first correction value and the second correction value; and determine, before calculating the third correction value, whether placement of the recording medium on the reading table is correct based on the density data.

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, segmenting at least a first digital image of the plurality of images into pixels associated with a foreground of the first digital image and pixels associated with a background of the first digital image, detecting a plurality of contours in the segmented first digital image, deciding, for each detected contour of the plurality of contours, whether that contour is an open contour or a closed contour, and determining that one or more sides of the document is out-of-bounds based, at least in part, on the decisions.

A control section of a reading device performs skew judgment based on an image of a preceding document scanned by the reading section to determine whether the side edge portion of the preceding document is displaced into a nip region sandwiched between a feed roller and a separation section. When it is determined that the side edge portion of the preceding document is displaced into the nip region and also the detection section, which detects a document placed on the placement section, detects a subsequent document, the control section determines a transport error.

An image forming apparatus includes a processing circuit. The processing circuit is configured to acquire setting information registered in advance by the user, determine a display mode of a list display of the setting information according to a priority assigned to the setting information or whether a job applying the setting information is executed, and control a display device to display the list display based on the display mode.

An image reading apparatus and an image reading method is provided. The apparatus and method are capable of efficiently performing a check process for determining whether a document has been forgotten after image reading only in an appropriate case. Whether a process for detecting a forgotten document is necessary to be performed is determined prior to the process every time after a reading process for reading an image of a single page.

What is disclosed is a system and method for detecting a folded page in a digital image of a scanned document. In one embodiment, the present method involves receiving a digital image of a document which has been converted to a digitized form using a document scanning device. The digital image is segmented horizontally and vertically to obtain a plurality of image segments. An edge profile is generated for the horizontal and vertical segments. A determination is then made, based on a comparison of the profiles, whether a page fold exists in the digital image. If a page fold is determined to exist in the digital image, the user is notified and the digital image is not sent to a print engine. Otherwise, the digital image is printed.

An image forming apparatus of an internal ejection type in which a sheet ejection space is provided between an image reader and an image former, the image forming apparatus includes: an illuminator provided on a wall surface partitioning the sheet ejection space; a detector that detects a position of a work target enabled to move in pulling-out and storing directions within the sheet ejection space; and a controller that performs on/off control of the illuminator depending on a detection position of the detector, wherein in a case where it is detected that the work target is in a work position for performing human work, the controller performs on/off control of the illuminator to illuminate a work target portion that faces an interior of the sheet ejection space of the work target and is subjected to the human work.

A print management system having a control apparatus and an image forming apparatus with sheet feeding cassettes includes a sheet data registration unit to register sheet data indicating an attribute of each print sheet, a sheet feeding cassette selection unit to select a sheet feeding cassette, and a sheet data selection unit to select sheet data about at least one type of print sheet from the registered sheet data. An adjustment value setting unit sets adjustment value information during image formation while feeding the selected print sheet and a database setting unit sets, in association with each other, the attribute of the selected sheet feeding cassette, the selected sheet data about the print sheet, and the set adjustment value information. The database setting unit allows setting to one piece of sheet data adjustment value information about each sheet feeding cassette selected by the sheet feeding cassette selection unit.

An image forming apparatus includes an image forming unit configured to perform a printing process of forming an image on a print medium based on print data, and a processor. The processor is configured to determine whether or not the printing process has completed based on remaining print data to be printed, when the print medium is removed from a paper discharge tray in which the print medium on which the image is formed by the image forming unit is placed, and to cause a warning to be output upon determining that the printing process has not completed based on the remaining print data to be printed.
