2906* Tailing Correction
2906 1 Shift Value
Shifts the image across the page at the interval specified by SP2906 2.
When making many copies of an original that contains vertical lines (such as a
table), separation may not work correctly, then a tailing image will occur (ghosts of
the vertical lines will continue past the bottom of the table). This SP prevents this
problem.

2906 2 Interval
Changes the interval for the image shift specified by SP2906 1.
