DUPLEX TESTS
These tests display if a duplex option is installed.
Quick Test
This test verifies if 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 (Continuous) until
Return or Stop is pressed.
You must use either Letter or A4 paper.
To run the Duplex Quick Test:
1.
Select Quick Test from the DUPLEX TESTS 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 or Stop to exit the test.
Check the Top Margin Offset of the base printer.
