Idea behind the adjustment
The Vacuum Feed LCIT blows air to the leading and side edges of the paper to separate
the topmost sheet from the stack, sucks up the sheet, and feeds it with a belt. Paper with
large curls hinders this function and affects the feed performance.
Face-curl increases the risk of double-feeds, because the air flow pushes up the paper.
Face-curl
Back-curl increases the risk of no-feeds, because the air flow presses down the paper.
Back-curl
In both cases, reducing the air flow improves the situation because the force applied to the
paper is reduced. For no-feed jams, increasing the vacuum power can also produce good
results.
