A method of testing a functional unit includes an optical sensor system (28) for detecting an optical signal from at least a part of a moving material web (14), a data processing system (36) for valuating the optical signals, and a display (38) displaying a state of the material web (14) and arranged in a sensitive range (30) of the sensor system (28).

A printing apparatus has: a paper tray having edge guides, each of which can guide one edge of paper in its width direction intersecting the transport direction of the paper; a paper width sensor that detects a paper width allowable in the paper tray according to the positions of the edge guides; a display controller that displays, on a display unit, a paper size selection screen on which candidate paper sizes corresponding to the paper width detected by the paper width sensor are displayed; and a selected size storage section that stores, in a storage section, paper selection information in which the paper width and the paper size selected on the paper size selection screen are related to each other.

An image forming apparatus includes a discharging tray for supporting a sheet, an operation panel and a supporting member. The sheet is discharged toward a sheet discharging direction that is a direction toward which the sheet is discharged. The operation panel is located at a position which is different from the position of the discharging tray in a width direction orthogonal to the sheet discharging direction and above the discharging tray. The supporting member is disposed at the discharging tray and capable of supporting the discharged sheet with the discharging tray. A front end portion of the supporting member is located above an upper surface of the discharging tray. At least a part of the front end portion of the supporting member overlaps the operation panel when viewed in the width direction.

An image forming apparatus includes first and second sheet storages, a sheet conveyer, an image reading unit configured to read a surface of a sheet conveyed from the first sheet storage by the sheet conveyer, an image forming unit configured to form an image on the sheet conveyed from the image reading unit, and a controller. The controller is configured to determine an amount of a color material appearing on the surface of the sheet based on image data generated by the image reading unit, determine one of the image forming unit and the second sheet storage as a sheet feeding destination, based on the determined amount of the color material and a threshold value that is associated with at least one of a type and content of an image to be formed on the sheet, and control the sheet conveyer to convey the sheet to the sheet feeding destination.

A friction sheet feeding machine is provided. The friction sheet feeding machine comprises a hopper configured to hold a stack of items. The friction sheet feeding machine also comprises a receiver configured to receive an item from the stack of items. The friction sheet feeding machine also comprises a separating mechanism configured to separate the item from the stack of items. The separating mechanism comprises a drive mechanism. The drive mechanism is configured to operate in a forward direction and a reverse direction. The friction sheet feeding machine also comprises a controller configured to generate signals to the drive mechanism to operate in the forward direction for a first period of time, and in the reverse direction for a second period of time.

A transport device includes a transport section, a processing section, a detector, and a transport controller. The transport section transports a sheet. The processing section performs processing on the sheet. The detector detects a movement of a pointing instrument on a detection surface of the detector itself. The transport controller allows the sheet to be transported by a distance corresponding to the movement of the pointing instrument, and in a direction corresponding to the movement of the pointing instrument.

A sheet folding apparatus includes a sheet folding unit disposed to fold a sheet and a conveyance unit disposed to feed the sheet to the sheet folding unit in a feed direction orthogonal to a fold direction of the sheet folding unit while correcting a skew of the sheet. The conveyance unit includes an elongated reference guide, a conveyance mechanism disposed to convey the sheet in the feed direction while exerting a force on the sheet toward the reference guide, an adjustment mechanism disposed to adjust an inclination of the reference guide with respect to the feed direction. The apparatus further includes an input unit through which a user inputs a folding misalignment amount of the sheet folded by the sheet folding unit. The inclination of the reference guide is corrected by the adjustment mechanism based on at least the folding misalignment amount inputted through the input unit.
