Advance rotation of the cam
I
In sort mode, the lead cam rotates in advance.
To ensure that the bins are in position before the copy arrives, the lead cam is
first rotated the equivalent distance to the width of the flat section. The move-
ment commences when PI3 detects the leading edge of the sheet. The bin will
not move.
When the sheet leaves PI3, the rotation of the cam will continue for the length
of the slope until the flat section is reached. The bin will be moved.
