ABSTRACT:
A metering roller and feed guide are included in a desktop printer between a first roller and a print zone. During first side printing, a media sheet is fed along the first roller and directed by an upper feed guide over the refeed guide to a second roller. The metering roller feeds the media sheet through the print zone. As the trailing edge approaches a metering pinch line, the metering roller stops. After a drying time, the second roller reverses direction moving the media sheet back toward the refeed guide. The refeed guide blocks the original path and directs the media sheet toward a repick guide and the first roller. The media sheet is fed onto the first roller for second side printing. In one embodiment the media sheet is wrapped around the first roller and unwrapped into the input tray during the refeed process to accommodate long media sheets.
