Abstract: A media processing device includes: a platen roller configured to move a media unit along a media processing path to traverse a printhead adjacent to the platen roller; an upstream drive assembly including (i) an upstream stationary roller disposed along the media processing path on a first side of the platen roller; and (ii) an upstream movable roller adjacent to the upstream stationary roller; a downstream drive assembly including (i) a downstream stationary roller disposed along the media processing path on a second side of the platen roller; and (ii) a downstream movable roller adjacent to the downstream stationary roller; a controller configured to control a motor to move, according to a predefined sequence, the upstream movable roller and the movable roller between respective engaged and disengaged positions.
