2.5 JUNCTION GATE MECHANISM
The junction gate [A] directs any paper reaching the bridge unit to either the upper tray (on
top of the bridge unit) or to the fi nisher, depending on which has been selected.
If the junction gate solenoid has been activat ed, the junction gate [A] points downward and
directs the paper to the upper tray [B] (dott ed line path in illustration). When the solenoid is
off, the junction gate points upward and the paper...](http://img.usermanuals.tech/thumb/64/98663/w64_mp-c3000-service-manual-1509271621_d-964.png "Page 965
