7.Detailed Descriptions

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.
