ABSTRACT:
During first side printing, a media sheet is fed along a feed roller over a refeed guide toward a metering roller and into a print zone. As the trailing edge approaches a metering pinch line, the metering roller stops. After a drying time, the rollers reverse direction. The refeed guide directs the media sheet around the metering roller onto an inner guide having a reversible roller. When the trailing edge of the media sheet clears the refeed guide, the reversible roller is moved into contact with the metering roller causing such roller to reverse direction. The media sheet now moves back along the inner guide onto the feed roller. When the media sheet trailing edge is detected at the feed roller, the feed roller and metering roller change direction back to the original direction. The media sheet now is fed through the print zone for second side printing.
