Patent number: 10464349Abstract: 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.Type: GrantFiled: July 6, 2017Date of Patent: November 5, 2019Assignee: Datamax-O'Neil CorporationInventors: Ramanathan Alaganchetty, Rajan Narayanaswami
