An image forming apparatus includes: an operation unit that is decentered from a center line between a right part and a left part of the image forming apparatus rightwards or leftwards and that is disposed closer to a rear face or a front face of the image forming apparatus; a human sensor that detects a user intending to use the image forming apparatus; and a controller that performs control of operation of the image forming apparatus by using a detection result of the human sensor, the human sensor having a detection range set to detect the user, the user being detectable even when the user is present at least partially outside a width range of the image forming apparatus.

An information processing apparatus includes a processor configured to, in a case where a time specified processing instruction to execute a specified process at a specified time is set, in response to detecting presence of a user near the information processing apparatus upon restoration from an energy save mode to a normal operation mode, hold a time specified processing instruction scheduled for a past specified time that is time before the restoration, the time specified processing instruction being held not to be executed upon the restoration.

An image forming apparatus includes: a human presence sensor that detects a user who uses the image forming apparatus; a first covering provided in front of the human presence sensor; and a second covering provided in front of the first covering, the second covering being configured not to interfere with detection of a detection target by the human presence sensor.

A reading device includes: plural transport rolls that transport a document along a transport path, include a discharge roll disposed on a most downstream side of the transport path, and rotate and do not rotate in synchronization with one another; an opening and closing unit that exposes or covers an upstream portion of the transport path; plural detectors that are provided apart from one another along the transport path, detect a transported document, and include a discharge detector that is disposed on a most downstream side of the transport path and is disposed on an upstream side relative to the discharge roll in a document transport direction; a reader that reads an image formed on a transported document in a downstream portion of the transport path; and a controller that stops the plural transport rolls once upon occurrence of a document jam inside a device body by controlling the transport rolls and rotates the transport rolls for only a predetermined period in a case where the discharge detector is detecting no document and a length of a document is equal to or longer than a threshold length.

A sheet conveyance apparatus includes: a speed detection roller that detects a conveyance speed of a sheet by coming into contact with the sheet being conveyed and being driven to rotate; and a hardware processor that performs temperature control to make an ambient temperature of the speed detection roller a predetermined temperature.

A sheet discharge device includes a sheet discharge tray, a stopper, a sheet size detection unit, and a display unit. In the sheet discharge tray, sheets discharged from a sheet discharge port are stacked on the upper surface. The stopper is provided on a upper surface side of the sheet discharge tray and is movable to a position corresponding to the leading end of each of a plurality of sheet sizes to be used in a sheet discharge direction, and regulates the position of the leading end of the sheet. The sheet size detection unit detects the sheet size corresponding to the position of the stopper. The display unit visually displays the sheet size detected by the sheet size detection unit.

An image forming system includes an image forming unit, an inspection unit, a conveyance unit configured to convey a sheet to the inspection unit, a controller configured to execute a first inspection mode in which a sheet having an image formed thereon is conveyed by the conveyance unit to the inspection unit and is inspected, and a second inspection mode in which, without executing image forming by the image forming unit, a sheet is conveyed by the conveyance unit to the inspection unit and is inspected, and a setting unit configured to set a recovery process. The setting unit permits the setting of the recovery process in the first inspection mode and prohibits the setting of the recovery process in the second inspection mode.

An image reading apparatus includes an original tray on which an original is to be stacked; a conveyance unit configured to convey the original stacked on the original tray; a reading unit including a reading sensor having a light receiving element to receive light of a first color and a light receiving element to receive light of a second color that is different from the first color, wherein the reading unit is configured to read an image of the original conveyed by the conveyance unit by using the reading sensor to generate image data which represents a reading result of the reading unit; at least one processor configured to: determine a first abnormal position which is a position in a first direction of an abnormal pixel of the first color in the image represented by the image data, wherein, in the image represented by the image data.

A control device includes a first control substrate and a second control substrate each of which includes a processor, a first communication interface, and a second communication interface, the first control substrate and the second control substrate being connected to each other via the first communication interfaces, in which the processor of the first control substrate or the processor of the second control substrate is configured to perform data communication via the second communication interfaces in a case where connection via the second communication interfaces is detected after an error of the data communication performed by the first communication interfaces is detected.

There is provided an information processing apparatus. The information processing apparatus acquires image data of a document read via a scanner; detects a streak included in the image data acquired by the acquisition unit by using a parameter for detection processing of detecting a streak; transmits the image data, the parameter, and a detection result obtained by the detection unit to an external apparatus; and changes the parameter used by the detection unit upon reception of a change in the parameter from the external apparatus.
