Place the Print Quick Test page on the ADF tray, and then select Front ADF Registration.
Note: To align the front ADF registration, place the test page faceup, short edge first into the ADF.
Select Copy Quick Test.
Compare the Copy Quick Test page with the original document.
Note: If the margins of the test page are different from the original document, then adjust Horizontal Adjust and Top Margin.
Repeat step 3 and step 4 until the margins of the Copy Quick Test page closely match the original document.
