A printing apparatus that includes a holding unit configured to hold a roll sheet performs supplying the sheet by rotating the roll sheet held by the holding unit; nipping and conveying the supplied sheet; performing printing on the conveyed sheet; detecting occurrence of a print medium jam of the sheet; and, if the printing apparatus has detected a print medium jam of the sheet, performing a control process of supplying the sheet in a state in which the conveying is stopped.

The present application relates to a tracking arrangement for the tracking of a material defect in a sheet material, such as a container material or a product-packaging material. The tracking arrangement may comprise a defect sensor, which is configured to detect a material defect in a sheet material moving thereby or therethrough. The tracking arrangement may also comprise a first structure sensor, which is configured to detect at least one inherent structural feature of the sheet material itself in the region of the material defect, as well as a control arrangement, which is configured to receive data from said first structure sensor.

A method of film production includes the steps of obtaining defect information including information on the position of a defect (D) in a separator original sheet (12b), slitting the separator original sheet (12b) to produce a plurality of separators (12a), and determining, on the basis of the defect information on a single defect (D), that a separator (12a) actually having the defect (D) and another separator (12a) adjacent to the above separator (12a) are defective.

A printer includes a transport unit that transports continuous paper, a medium support unit in which a support surface that is capable of supporting continuous paper that is transported by a transport unit, and first concave sections, which are indented from the support surface, are formed, and an image capture unit, which is disposed on a lower side of the support surface, and which captures an image of a lower surface of the continuous paper.

An apparatus and method for stretch wrapping of a palletized load uses film tension feedback derived from a film tension control load cell to control film dispensation. The load cell measures film tension and the film payout rates is determined by the film tension. Film tension values are used to determine when an out of bounds condition occurs, namely, when a film break has occurred, or when a possible film break is about to occur or when the film has been cut at the end of a wrapping cycle. To prevent film free end entanglement caused by a break, clamps engage the film so the film tail is controlled, eliminating the risk of recoil. The broken film tail may then be quickly and reliably reattached to the rotating load in a desired position.

In one example in accordance with the present disclosure a device to detect media being wound around a wheel is described. The device includes a reel that collects the media and a movable arm pivotally coupled to the reel to provide tension to the media being wound around the reel. The device also includes a controller that detects media is being wound around the reel by 1) determining an angular position of the movable arm and 2) calculating, based on the angular position of the movable arm, when an output of a motor that rotates the reel is non-zero.
