摘要:
A second feed roller of smaller diameter than a first feed roller is included in a media handling system. A print zone is located adjacent to the second feed roller away from the first feed roller to lower the location of the print zone. During ejection, a pivot mechanism moves from a first position adjacent to the printhead to an intermediary position. This causes arms to extend and rails to retract. The motions then pause and/or reverse, prior to full extension and full retraction. Next, the pivot mechanism moves to a second position causing the arms to fully extend and the rails to fully retract. The varied motion (e.g., pause and/or reversal) assures that the arms push at an edge of the media sheet to reliably move a media sheet into an output tray without the media sheet sailing from the printer.
