Damaged
single sheet
folded paper.

Phenomenon

Single folded sheets may be damaged when ejected by the nisher, depending on the paper type.

Cause

The ejection speed by the booklet rollers is faster than the speed of the booklet blade.
This increases the load on the paper.

Solution

The ejection speed of the booklet rollers has been changed from 60mm/s to 90mm/s to synchronize
the speed between the booklet rollers and the booklet blade.
