6.17.2 INVERTER/DUPLEXING JUNCTION GATES
This inverter/duplexer unit has three junction gates:
[JJ]: Exit junction gate
[KK]: Switchback junction gate
[LL]: Invert/duplex junction gate
The exit junction gate [A]:
• Closes for straight-through feed (neither face-up nor duplexing selected) and the
paper goes out of the machine face-up.
• Opens to feed paper down into the inversion tray for inversion/duplexing
The switchback junction gate [B]:
• Opens before paper arrives so it can feed onto the inversion tray and into the
switchback rollers [D]
• Closes to keep the paper down and horizontal so that it will feed out properly
after the switchback roller reverses.
The invert/duplex junction gate [C]:
• Closes so that paper passes over it and into the vertical feed path for face-down
output only (no duplexing).
• Opens to guide paper down into the duplex unit so that the paper can return to
the main feed path for printing the 2nd side of the sheet.
