Vacuum Feed LCIT
Frequent Double Feeds, Failure to Feed
Cause:
Side fence/rear fence are not set correctly.
Paper with excessive buckle [A] can cause double-feeding. Make sure that the fences are at their
correct positions so the paper lies flat [B].
Paper Curl
[A]
Concave curl. Paper exits with curve down.
[B]
Convex curl. Paper exits with curve up.
In either case, if the curl is excessive (not within specifications), this can cause double-feeding.
