Accumulation of background at the leading edge
Follow these steps for accumulation of background at the leading edge.
In some cases (high coverage jobs, noticeable with rich black design) a narrow band may appear at the
trailing edge area, across the frame. See example below:

When this issue is noticeable do the following:
1.
Verify LE BID engage is calibrated properly. Re-calibrate per need.
2.
Enable the “overlap prevention” feature. (See
Automatic overlap adjustments
on page
17
).
3.
Use the overlap manual correction screen under Job Properties and re-adjust the BID engage by
forwarding it by +10 mm. (See
