Solution
Do the following:
1. Increase the margins the leading/trailing edges (up to a maximum of 10mm).
See “Margin Adjustments”.
Note: If you adjust the margins without adjusting the image position, parts of the image may not
be printed. To adjust the image position, see Step 2 below.
2. If the symptom still occurs, try adjusting the position of the image at the same time.
Change the value in increments of -0.5mm, up to a maximum width of 10mm.
IMPORTANT: Before you make any registration adjustments, make sure that the
margin in the direction you will move the image is wide enough.

precision-adjusted at the factory).
