Perforated Paper
A perforation is a series of holes punched through the paper to aid in the separation of
one piece from another. Perforated paper can cause jams, misfeeds, and even printer
damage. The following guidelines should be used when ordering perforated paper:
n Perforations should be free from any burrs and paper dust to avoid multiple feed,
contamination, or paper jam problems.
n Avoid use of perforations that are not flat.
n The ratio of cut to uncut in a perforated line should be 1:1.
n Perforations must not extend to the edge of the page. The minimum distance from
perforation to edge of the pages is 50 mm.
n The maximum number of perforated lines per page is 3 horizontal and 2 vertical.
