An image forming apparatus, provided with an image forming part that performs an image formation on each of individual medium pieces that are attached to a long base sheet with specified gaps wherein a long medium is configured with the long base sheet and the medium pieces, a length of the gaps being defined as a gap length, a carrying part that carries the long medium to the image forming part in a medium carrying direction, a cutting part that cuts the long medium that is being carried by the carrying part, and a cut position determining part that determines a cut position where the long medium is cut by the cutting part, the cut position being located at one of the gaps, wherein the cut position determining part changes the cut position according to the gap length.

A sheet feeding apparatus includes a stacking member, an optical sensor, a detected member, and a control unit. As an amount of sheets stacked on the stacking member decreases, the detected member moves from a first position in which optical sensor light is not interrupted, then once interrupts the light, and then moves to a second position in which the light is not interrupted. Information regarding an amount of sheets transmitted by the control unit, when stored information is about the detected member in the second position, is information notifying that an amount of sheets stacked on the stacking member is less than that of information regarding an amount of sheets stacked on the stacking member transmitted by the control unit when stored information is about the detected member is in the first position.

A sheet processing device, including measuring equipment for measuring a property of media sheets to be processed in the device, and a controller arranged to control a processing operation of the device on the basis of the measured property. The device includes a media property output interface connected to at least one data line for transmitting the measured property to another sheet processing device.

A user is allowed to set contents of imaging work for digitization of a book using a page turning device to turn over each page of the book in a spread state from an original position to a destination position and settings of the imaging work are stored in advance. When a user commands initiation of the imaging work, the stored settings are confirmed and an imaging operation screen to present, to the user, guidance information related to an imaging procedure corresponding to the settings is separately displayed.

An image forming apparatus capable of making a match between the orientation of a reference side of a sheet along which punched holes are formed and the orientation of an output image on the sheet in double-sided printing. It is determined whether or not to rotate an image based on whether the image is printed in a single-sided printing mode or a double-sided printing mode. In the double-sided printing mode, a reverse-side image is printed on a first surface of the sheet, the sheet is conveyed into the printing section through a double-sided conveying path, a front-side image is printed on a second surface of the sheet, and the sheet is discharged. In the single-sided printing mode, an image for single-sided printing is printed on a first surface of the sheet, and the sheet is discharged.

According to one embodiment, a system for a decoloring information management of a decoloring apparatus includes an decoloring processing unit, a sheet conveying unit, a sheet reading unit, a user ID reading unit, a storing unit configured to store a predetermined information, and a control unit. A sheet on which an image is formed with an decolorable colorant is subject to decoloring processing. The sheet conveying unit conveys the sheet and causes the sheet to pass through the decoloring processing unit. The sheet reading unit is arranged further on an upstream side than the decoloring processing unit. The user ID reading unit reads ID information of a user. The storing unit stores predetermined information. The control unit controls the storage unit to correlate the user ID and the read information by the sheet reading unit.

In an image forming apparatus, a paper sheet cassette stores a bunch of paper sheets to be fed. A media sensor unit measures a thickness and a surface roughness of one paper sheet fed and transported from the paper sheet cassette. A residual sheet amount sensor detects a residual amount of the paper sheets in the paper sheet cassette. A residual sheet number estimating unit estimates the number of residual paper sheets in the paper sheet cassette on the basis of (a) a thickness of a bunch of the paper sheet in the paper sheet cassette, the thickness of the bunch corresponding to the residual amount detected by the residual sheet amount sensor and (b) the thickness of the one sheet and the surface roughness of the one sheet measured by the media sensor unit.

An image processing apparatus acquires a plurality of first images and one or a plurality of second images. The first images are acquired through a first reading operation in which a reading apparatus sequentially reads first sides of a plurality of document sheets. The second images are acquired through a second reading operation in which the reading apparatus reads second sides of one or more of the plurality of document sheets. In a case where the number of second images acquired is smaller than the number of first images acquired, the image processing apparatus determines a sequence of the plurality of first images and the one or the plurality of second images such that sequential numbers of the one or the plurality of second images are differently set depending on whether an interrupting factor has arisen.

An image forming apparatus includes a generating unit, a print instruction providing unit, and a display. The generating unit generates print data of a sample sheet if a request for outputting the sample sheet is received while print data formed of plural pages is being generated. The print instruction providing unit provides a print instruction for the print data of the sample sheet after providing a print instruction for the print data that has been generated. The display displays, based on the print data of the sample sheet, an attribute of the sample sheet.

An image forming apparatus includes an image former that prints a color chart on a sheet, an in-line colorimeter that performs color measurement of color patches formed on the color chart, and an image processor that performs color adjustment based on colorimetric values of the color patches formed on the color chart. The image processor combines multiple divided colorimetric data obtained by performing color measurement of color patterns into which a chart is divided, the chart in which color patches are arrayed to be common to the color chart, and obtains colorimetric values of the color patches formed on the color chart from the multiple divided colorimetric data combined.
