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.
The paper you choose to print the page on should be either Letter or A4.
To run the Duplex Quick Test:
1.
Select Duplex Quick Test from the menu.
2.
Select Single or Continuous.
•
The single Duplex Quick test cannot be canceled.
•
The printer attempts to print the Quick Test Page from the default paper source. If the
default paper source only supports envelopes, then the page is printed from Tray 1.
•
Check the Quick Test Page for the correct offset between the placement of the first scan
line on the front and back side of a duplexed sheet.
•
If adjustment is necessary the Top Margin Offset must be adjusted first. The range of the
adjustment is -25 to +25. The Duplex Top Margin Offset range is -20 to +20.
•
Adjustment of this setting lets you shift up or down the position of the Top Margin. Changing
this parameter by 1 unit moves the margin 1/100 inch. A positive offset moves the text
down the page and widens the top margin while a negative offset moves the text up the
page and narrows the top margin.
3.
Press Return/Stop to exit the test.
Check the Top Margin Offset of the base printer.

displays, when the sensor/switch is open, OP (Open) displays.
