Exit
Roller
The junction gate solenoid drops the junction gate, and the
original feeds up towards the reverse roller, instead of down into
the exit tray.
When the trailing edge of the original has passed the exit roller,
the junction gate solenoid turns off, and the reverse roller feeds
the original back into the ARDF.
The second side is scanned.
After scanning the second side, the machine inverts the original
again, so that it is stacked correctly in the exit tray.
