Abstract
A method and apparatus for deskewing a sheet of media traveling through a paper path in a printer is provided. A buckle is formed in the sheet of media by over-driving the sheet into stationary deskew rollers that form a deskew nip downstream. A deskewing bias element includes a plurality of articulated segmented surfaces that contact the buckle and urge the leading edge of the sheet into the deskew nip. The buckle force combined with the biasing force from the deskewing bias element aligns the leading edge of the sheet with the deskew nip across the full width of the sheet, thereby removing any skew.
