ABSTRACT:
A paper handling system is provided which allows for controlled passage of a pivot between a normally biased initial position and a task-performing position. The pivot includes a sheet-directing member and a track which is fixed relative to the sheet-directing member and is movable to the task-performing position in opposition to pivot bias. A follower, which is configured for selected travel along the track, selectively applies a force against the track in opposition to biased sheet-directing member movement. A processor-controlled printhead carriage is used to trigger and then to regulate pivot rotation.
