A method, non-transitory computer readable medium, and apparatus for automatically adjusting a feeder tray of a printing device are disclosed. For example, the method receives a signal to initiate a feeder tray adjustment routine, wherein the feeder tray adjustment routine determines an amount of lateral adjustment of the feeder tray to eliminate a lateral input error of a print media that is fed to a registration subsystem of the printing device, activates a mechanism to adjust a lateral position of the feeder tray by the amount that is determined, and feeds subsequent print media through the registration subsystem for printing an image on the subsequent print media.

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 sheet conveying device, which is included in an image forming apparatus and a post processing device, includes multiple position detectors and a position corrector. The multiple position detectors are aligned along a sheet conveying direction and configured to detect a side end of a sheet. The position corrector is configured to convey the sheet and correct a position of the sheet based on a positional deviation amount of the sheet, obtained by a detection result of the multiple position detectors. The positional deviation amount of the sheet is obtained by an extreme downstream position detector in the sheet conveying direction, of the multiple position detectors. A position of a subsequent sheet is corrected based on a sum of the positional deviation amount of the sheet and a positional deviation amount of the subsequent sheet.

A sensor unit includes an edge detection sensor, a sensor carriage, a unit housing, and a carriage moving mechanism. The edge detection sensor is arranged in a conveying portion for conveying a sheet and senses edge positions at both sides in a sheet width direction perpendicular to a sheet conveying direction. The sensor carriage has a carriage main body in which the edge detection sensor is incorporated, and is reciprocatably supported on the unit housing in the sheet width direction. The carriage moving mechanism makes the sensor carriage reciprocate in the sheet width direction. The sensor carriage is selectively positioned at a first position where it makes contact with a first side face at one end side of the unit housing in the sheet width direction or a second position where it makes contact with a second side face at the other end side in the sheet width direction.

A registration system for a printing device and a method for controlling the same are disclosed. For example, the registration system includes at least one sensor to detect a position of a print media, at least one laterally adjustable nip, wherein the laterally adjustable nip moves along an inboard direction and an outboard direction, a motor coupled to the at least one laterally adjustable nip to move the at least one laterally adjustable nip a desired amount of movement based on the position of the print media and a width of the print media, and a processor communicatively coupled to the at least one sensor and the motor to calculate a desired amount of movement based on the position of the print media and control the motor to move the at least one laterally adjustable nip by the desired amount of movement.

An image forming apparatus includes: a transfer section including a transfer body that transfers an image onto a sheet in a transfer nip; a belt position correction section that performs operation of correcting misalignment of a position in an axial direction of a transfer belt in the transfer nip; a sheet conveyance member that is provided on the upstream side of the transfer nip in a sheet conveyance direction and conveys the sheet; and a hardware processor that controls the sheet conveyance member so as to displace the sheet along a width direction of the sheet. The hardware processor controls displacement of the sheet conveyance member so as to follow the position in the axial direction of the transfer belt at the transfer nip.

A sheet conveying device includes a position detector configured to detect a position of a side end portion of a conveyance target medium, a position adjuster configured to move in at least one of a width direction of the conveyance target medium and a rotation direction of the conveyance target medium within a plane of sheet conveyance, while conveying the conveyance target medium, and adjust a position of the conveyance target medium, according to the position of the side end portion of the conveyance target medium detected by the position detector, a transfer rotary body disposed downstream from the position adjuster in a sheet conveying direction and having a receiver mounted on the rotary body to receive the conveyance target medium, and circuitry configured to change a rotation speed of the transfer rotary body according to the position of the conveyance target medium after adjusted by the position adjuster.

A sheet transport device includes a sheet load tray on which a sheet is loaded, a side-edge positioning unit, and a regulating unit. The side-edge positioning unit comes into contact with a side edge of the sheet in a direction intersecting a sheet transport direction at an upper surface of the sheet load tray and positions the side edge of the sheet to a normal position. The regulating unit is provided in a rotatable manner about a rotation shaft at a lower surface of the sheet load tray and regulates an output position of the sheet by rotating a stopper of the regulating unit to a position where the stopper is capable of colliding with a downstream edge of the sheet to be output in an output direction when the side-edge positioning unit moves to a position corresponding to a minimum width of the sheet.

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).
