An image forming apparatus which eliminates the need for a paper thickness detection sensor and saves time and effort for a user when performing remote scanning. An image reading unit of the image forming apparatus is connectable to an external client via a network and generates image data by reading an original. In the remote scanning, the image reading unit reads the original conveyed by a conveying unit in accordance with an instruction from an external client. A conveying speed at which the original is conveyed by the conveying unit when the remote scanning is performed is set in accordance with an original thickness setting. A first original thickness setting made on the image forming apparatus and a second original thickness setting made on the external client are obtained. When the second original thickness setting is different from the first original thickness setting, the original thickness setting is set to the second original thickness setting.

An information processing device according to aspects of the present disclosures is configured to obtain remaining amount information regarding a remaining amount of the consumable in use from a managed device, and obtain stock amount information regarding a stock amount of an unused consumable from an information source. When the consumable is replenished or replaced, the information processing device determines whether or not the stock amount of the consumable is equal to or less than a threshold value that is defined as a determination criterion based on the remaining amount information and the stock amount information, and displays a consumables management screen displaying a status object indicating a status of the consumable that is determined, in the determining process, that the stock amount is equal to or less than the threshold value.

A sheet feeding apparatus includes a control unit. After finishing feeding the sheet, if the sheet detection unit does not detect the sheet when the lift plate is positioned at the sheet feeding position, the control unit sets the waiting position to a lowest position. Further, if the sheet detection unit detects the sheet and if the remaining amount detection unit detects that the remaining amount of the sheets is a predetermined amount or less, the control unit sets the waiting position to a height position between the sheet feeding position and the lowest position. Further, if the sheet detection unit detects the sheet and if the remaining amount detection unit detects that the remaining amount of the sheets is more than the predetermined amount, the control unit sets the waiting position to the lowest position.

An image reading apparatus including: a conveyor that conveys a sheet on which an image is formed by an image forming apparatus; a reader that reads the sheet conveyed by the conveyor, by using a contact image sensor; and a first hardware processor that extracts an edge of the sheet by analyzing a read image by the reader, calculates a blur amount of the edge based on the extracted edge, and calculates a curl amount of the sheet based on the calculated blur amount.

A billing system used together with an image forming apparatus for forming an image on a sheet and discharging the sheet includes: a counting unit for counting, when a print job is interrupted, a billing unit number for a sheet which already has an image formed thereon when the interruption occurs and which has not discharged from the image forming apparatus; a determination unit for determining whether the print job is continued or cancelled after the print job is interrupted; and a billing unit for counting a billing counter corresponding to an amount for which the image forming apparatus is used, and billing a user who uses the image forming apparatus according to the billing counter, wherein the billing unit switches whether the billing counter is counted by using a count result of the counting unit in accordance with a determination result of the determination unit.

A medium conveying apparatus includes a processor to detect edge pixel from a first line image and a second line image, select a first surface or a second surface of the medium, based on the number of the detected edge pixels, a comparison between a gradation value of each of the detected edge pixels and a gradation value of a peripheral pixel of each of the detected edge pixels, or a variation of gradation values of pixels within a predetermined distance from each of the detected edge pixels or the peripheral pixel of each of the detected edge pixels, estimate a shape of the medium based on a line image acquired by imaging the selected surface, and control a conveying roller or cut out a medium image from the first line image and the second line image and output the medium image, based on the estimated shape.

An image forming apparatus includes: a tray on which at least one sheet is loaded; a sensor and a controller. The sensor measures overall weight of the sheet loaded on the tray. The controller calculates decrement from the overall weight measured by the sensor upon completion of a job. The controller calculates total weight of the sheet loaded on the tray through execution of the job. The controller executes a logout process based on the decrement and the total weight.

Provided is an image-forming device that improves convenience for a user. The image-forming device includes a plurality of power-supply stages, remaining paper amount detection sensors, and a system control unit. A remaining paper amount detection sensor detects the remaining paper amount in a paper-supply stage. When the remaining paper amount that is detected by the remaining paper amount detection sensor is less than a fixed value, the system control unit sets the paper-supply stage having a paper amount that is less than the fixed value as a FAX use only paper-supply stage.

An image processing apparatus includes a data processing part that processes image data: a storage part that stores billing information including a plurality of wireless communication identifiers and usage histories of the data processing part, each of the usage histories being associated with wireless communication identifiers, a communication part that establishes a wireless communication associated with one of the wireless communication identifiers such that the communication part wirelessly communicates with an external device, and a control part that, when receiving an image processing job from the external device through the communication part, determines one of the wireless communication identifiers that is used to establish the wireless communication wherein the one of the wireless communication identifiers is defined as a destination identifier, controls the data processing part based on the image processing job and updates one usage history that is associated with the destination identifier.

Copy and scan printing may include scanning, by scanner disposed along a paper path between a paper delivery roller and a paper pickup roller, content of documents (302). Further, copy and scan printing may include determining whether the documents are to be copied (304), in response to a determination that the documents are to be copied, determining whether a page count of the documents to be copied is available (306), and generating copies of the documents (310).
