A sheet conveying apparatus includes a controller to set conveyance speeds of first, second, and third conveyance rotary members. The controller sets the conveyance speed of a sheet by the second conveyance rotary member to a first conveyance speed, which is the same as a conveyance speed of the sheet by the first conveyance rotary member, and a second conveyance speed which is different from the first conveyance speed. When the controller sets the conveyance speed of the sheet by the first conveyance rotary member to the first conveyance speed and sets the conveyance speed of the sheet by the second conveyance rotary member to the second conveyance speed, the controller sets the conveyance speed of the sheet by the third conveyance rotary member to a third conveyance speed which is a speed between the first conveyance speed and the second conveyance speed.

A positioning assembly (30) for positioning a sheet material, especially at an entry portion of a sheet material processing machine, is described. It comprises a support beam (32) on which at least a portion of a sheet material to be positioned can be placed and a plurality of clamping fingers (38). The support beam (32) is coupled to a drive unit (60) configured for translationally moving the support beam (32) along a travelling direction (y) of the sheet material, translationally moving the support beam (32) along a direction (x) transverse to the travelling direction (y) and rotationally moving the support beam (32) with respect to a pivot axis (z) being perpendicular to the traveling direction (y) and the transverse direction (x). Each of the clamping fingers (38) is coupled to an individual clamping finger actuation unit (40). Moreover, a sheet material processing machine comprising such a positioning assembly (30) is presented.

In some examples, the disclosure describes a device that includes a first media tray positioned at a media input of a pick and separation mechanism, a second media tray positioned at the media input of the pick and separation mechanism, a media scan guide to position a sheet of print media at the media input of the pick and separation mechanism, a shared media path comprising a turn roller to receive the sheet of print media from the pick and separation mechanism from a first direction and provide the sheet of print media to a print zone in a second direction, and an output zone to receive the sheet of print media from the shared media path.

A print device includes: a first opening via which a print medium is to be inserted or ejected; a second opening via which the print medium is to be ejected; a transport roller that transports the print medium; a housing that contains a transport route; a first sensor that detects presence of the print medium; and a second sensor that detects the presence of the print medium on an upstream side of the first sensor; and a processor. When a command designates the print medium to be ejected to the outside via the second opening and a length of the print medium determined from the detection states of the first and the second sensors is shorter than or equal to a predetermined length, the processor ejects the print medium to the outside via the first opening.

According to an example, an apparatus to prevent media transport jams may include an actuator to load and advance a media within a media path width. The apparatus may also include a first sensor and a second sensor to detect respective edges of the media, in which the first sensor and the second sensor may be positioned outside of a media action area and on opposite sides of the media path width. The apparatus may further include a controller to prevent the actuator from advancing the media along the media path in response to a detection of one or both of the first edge of the media by the first sensor and the second edge of the media by the second sensor.

A detecting device, which is included in an image forming apparatus, includes a detector configured to optically detect at least one of a position of a sheet, a position of an image formed on the sheet, and the image formed on the sheet, and a rotary body disposed at a position opposed to the detector and having a shaft, the rotary body being rotatable about the shaft in a sheet conveying direction of the sheet. The sheet is conveyed to space between the detector and the rotary body. The rotary body has a reference plane on an outer circumferential surface, a line formed on the reference plane and extending in a width direction perpendicular to the sheet conveying direction. The detector detects the line on the reference plane while the rotary body is rotating when the sheet does not intervene between the detector and the rotary body.
