Duplex Tests
Duplex Quick Test
This test is used to verify that the Duplex Option Top Margin is set
correctly. This test prints a duplexed version of the Quick Test Page
that can be used to adjust the Top Margin for the backside of the
duplexed page. You can run one duplexed page (Single) or continue
printing duplexed pages (Continues) until Return/Stop is pressed.

duplexed sheet.
