Print Registration

Use Print Test 1 or the Quick Test to evaluate print registration.
Adjust the registration so the tips of the diamonds are at the top and
bottom edges of the page and the printout is centered left to right.
Verify that the top margin is correct before adjusting the bottom
margin.
1. Enter Diagnostics mode.
2. Select [PRINT REGISTRATION].
3. Select one of the following: [Left Margin], [Top Margin], [Bottom
Margin].
4. The value of the margin you selected is shown.
5. Margins:
•
Left Margin can be set between -23 and +23. Changing the
number by one moves the margin 1/75 inches. Moving the
number in a positive direction moves the margin toward the
right and negative moves the margin to the left.
•
Top Margin can be set between -20 and +20. Changing the
number by one moves the margin by 1/75 inches. Moving
the number in a positive direction moves the margin down
the page and widens the top margin. Moving the number in a
negative direction moves the text up the page and narrows
the top margin.
•
Bottom Margin can be set between -20 and +20. Moving
the number in a positive direction moves the margin down
and narrows the bottom margin. Moving the number in a
negative direction moves the text up the page and leaves a
wider bottom margin.

to move the number in a negative direction. Select [SAVE] to
save your settings when they are correct.
