Left Margin; Top Margin - Lexmark MS312 Service Manual

Top Margin

This setting controls the offset between the placement of the first scan line on the front and back side of a duplex sheet.
Note: If adjustment is necessary, the top margin in the Registration menu must be adjusted first. The duplex top
margin may be adjusted next.
To adjust this setting:
1
From the Diagnostics menu, navigate to:
Duplex Tests > Top Margin
2
Change the margin value.
Changing the value by 1 unit moves the margin by 1/100 in. A positive value moves the text down the page and
widens the top margin. A negative value moves the text up the page and narrows the top margin.
3
Press OK to save the desired margin value.

Left Margin

This setting allows the user to shift the position of the left margin of the back side of a duplexed page to the left or
right. The default margin is 1/4 in.

Duplex Tests > Left Margin
2
Change the margin value.
Each increment corresponds to 4 pels at 600 dpi (0.00666 in. or 0.1693 mm). A more positive offset moves the
margin to the right, and a more negative offset moves the margin to the left.
