1 Duplex motor
2 Paper exit roller
3 Paper exit sensor
4 Registration sensor
5 Duplex sensor
An independent drive motor in the duplex machine handles paper ejection and reversing. Paper
from the registration roller is sent to the paper exit roller. The paper exit roller reverses its
rotation after the trailing edge of the paper has passed the paper exit sensor (but the paper has
not fully exited into the output tray), and then sends the paper into the duplex paper path. When
the trailing edge of the paper passes the duplex sensor, the paper exit roller again reverses
rotation (reverting to its original direction), and ejects the paper into the output tray.
The duplex sensor is also used to detect paper jams.
