An example apparatus is disclosed for transporting a substrate through a printing device. The apparatus comprises a shaft to carry the substrate, a motor to rotatably drive the shaft, a motor driver to provide a control signal to the motor to drive the shaft, a transport arrangement to draw the substrate from the shaft, and a controller to cause the motor driver to drive the shaft at a predetermined rotational speed, to cause the transport arrangement to apply tension to the substrate, and to detect a winding direction of the substrate on the shaft based on the control signal.

A sheet processing apparatus includes an entry portion, a sheet conveyance path extending from the entry portion, a skew correction roller pair that contacts a leading edge of a sheet conveyed in a predetermined direction from the entry portion to correct skew of the sheet, and a receiving path. The skew correction roller pair conveys the skew-corrected sheet in a direction opposite the predetermined direction. The receiving path branches from the sheet conveyance path from the entry portion to the skew correction roller pair to receive the sheet conveyed in the direction opposite the predetermined direction.

A printing apparatus comprises a conveyance control unit which controls conveyance of printing sheets so that a trailing edge of a preceding sheet as a printing sheet precedingly fed from the stacking unit and a leading edge of a succeeding sheet as a printing sheet succeedingly fed from the stacking unit overlap each other; and a skew correction unit which performs skew correction of the succeeding sheet while the succeeding sheet overlaps the preceding sheet by the conveyance control unit. The skew correction unit makes the leading edge of the succeeding sheet abut against the conveyance roller during a time from an end of a last line feed operation by the conveyance roller for printing on the preceding sheet by the printing unit to start of a next conveyance operation.

A sheet conveying device includes a detector configured to detect an attitude of a conveyance target medium, a corrector configured to perform a correcting operation based on a detection result of the detector, and circuitry configured to calculate an angular displacement correction amount and a lateral displacement correction amount of the conveyance target medium, cause the corrector to perform the correcting operation in a direction perpendicular to a sheet conveying direction, based on the lateral displacement correction amount, after the corrector grips the conveyance target medium, and cause the corrector to rotate by the angular displacement correction amount of the conveyance target medium before the corrector grips the conveyance target medium and to perform the correcting operation in a direction of rotation of the conveyance target medium, based on the angular displacement correction amount, after the corrector grips the conveyance target medium.

An ATM includes a sheet driving system with a sheet path along which sheets travel, and sheet sensors and sheet drive mechanisms adjacent the sheet path. One sheet drive mechanism is disposed apart from another sheet drive mechanism in a direction relative to the sheet path, and each sheet drive mechanism is selectively operative to change relative speed and direction of movement of disposed areas of a sheet as the sheet travels adjacent to the sheet drive mechanisms along the sheet path. A control system is responsive to sensing a sheet with a sensor to selectively actuate a sheet drive mechanism to change the position of the sheet relative to the sheet path.

A sheet stacking apparatus includes a sheet alignment mechanism configured for aligning a sheet in a predetermined reference position; a gripper arrangement configured to grip the aligned sheet at at least two spaced-apart points of the sheet and to release the sheet on a stack; and a holder configured to hold the sheet in position on the stack while the gripper arrangement releases the sheet. The gripper arrangement is movable along a predetermined trajectory for moving the sheet from the reference position to a stacking position.

A paper folding machine comprising folding mechanisms (11, 15, 24) arranged at folding positions (A-C) on a transport path (1), respectively, guides (8, 19, 20, 28, 29) positioning a paper sheet (F) relative to the folding positions by engagement with at least one side edge of the paper sheet, stoppers (12, 15, 25) stopping and positioning the paper sheet at the folding positions by bringing a leading edge of the paper sheet into contact with the stoppers, a fold misalignment detection unit (50) detecting a fold misalignment amount of the paper sheet for each folding position, and a controller (42) controlling positions of the guides and stoppers. The controller calculates, for each folding position, an average fold misalignment amount, and adjusts the position of the guide and/or stopper associated with the corresponding folding position so as to correct fold misalignment corresponding to the average fold misalignment amount.

An example roller adapter may comprise a cradle, a first roller rotatably disposed on a top side of the cradle, a second roller rotatably disposed on the top side of the cradle, and an alignment knob disposed on a base of the cradle. The first and second rollers may extend in a substantially parallel direction. The first and second roller may rotatably support a roll of flexible print media.

A medium conveying apparatus includes a plurality of feed rollers, each feed roller rotating independently at a respective speed to feed a medium, a first sensor located on a downstream side of the plurality of feed rollers in a medium conveying direction and also in a central part in a direction perpendicular to the medium conveying direction, to detect the medium, a second sensor and a third sensor located on both sides of the first sensor in the direction perpendicular to the medium conveying direction, to respectively detect the medium, and a processor to change the speed of one of the plurality of feed rollers at least until the first sensor detects the medium when any of the second sensor or the third sensor detects the medium and the first sensor does not detect the medium within a predetermined time.

A method of making a pad of labels comprises: printing display information on a top surface of a substrate; affixing a first layer of lamination material to a bottom surface of the substrate; affixing a second layer of lamination material to the top surface of the substrate, the second layer of lamination material having a release coating applied to a top surface thereof; applying an adhesive strip to a bottom surface of the first layer of lamination material, the adhesive strip being covered by a liner material; cutting the substrate having first and second layers of lamination material affixed into at least one label; removing the liner material to expose the adhesive strip after cutting the substrate into at least one label; and arranging the labels into a pad of labels.
