Abstract:
A mechanism for peeling protective backing from imaged print media in an image forming device having a rotatable platen, said mechanism comprising:a peel bar pivoted at a first end proximate to said rotatable platen and adapted to peel off imaged print media from a moving protective backing at a second end; an upper roller disposed proximate to said rotatable platen under said peel bar and adapted to be rotatably driven by said rotatable platen; and a lower roller disposed under said upper roller and adapted to be pressed against said upper roller when said platen is rotating, said upper and lower rollers adapted to rotatably drive said protective backing downstream from said second end of said peel bar past said rotating platen at a faster speed than the speed of said rotating platen, said upper roller having an outer surface not being in contact with said platen and adapted to allow slip to occur between said protective backing and said outer surface of said upper roller in order to tension said moving protective backing at said second end of said peel bar.
