  • Patent number: 10464349
    Abstract: A system to calculate line feed error in labels on a printer includes a holder assembly under the label line feed and before the printer burn line; a first sensor and a second sensor on the holder assembly, a fixed distance, L, between them; and a processor. The first sensor senses a first position of a label edge, L1A. The second sensor senses a second position of the label edge, L1B. The processor calculates the distance, L1AB, between the first position and the second position and calculates the line feed error over the fixed distance, L, by taking the difference (L?L1AB). The processor calculates the feed correction to be done to the label, given by [(L?L1AB)/L]×D, where D is a distance between the first sensor and the burn line of the printer. The processor instructs the printer line feed to implement the calculated feed correction.

  • Patent number: 7223033
    Abstract: A pinch control apparatus in a printer for controlling a pinch force exerted on a medium which is being fed into a printing zone is provided. The pinch control apparatus includes a camshaft rotatably mounted across a width of the medium, at least one cam attached to the camshaft, a plunger and a biasing rod. The cam has a predefined profile and is able to rotate with the camshaft. The plunger abuts the predefined profile of the at least one cam. The biasing rod extends from a pinch plate to the plunger to bias the pinch plate to a linefeed roller for exerting the pinch force on the medium therebetween. The pinch force exerted on the medium is controllable by the rotation of the camshaft.
