All papers curl to some degree. Excessive curl is one of the most
common causes of paper jams. Selecting a low-curl paper with
the proper moisture content makes a significant difference in the
productivity of your system. Refer to the operator guide for your
printer for paper curl recommendations specific to your printer.
Because the front and back surfaces of the paper, as determined
during the paper making process, differ slightly in their makeup,
one side is preferred as the side to image first. If you are using a
quality 24 pound/90 gsm paper intended for xerographic
purposes, the ream wrapper is marked with an arrow that
indicates the preferred printing side. Print on this side for one-
sided printing. For two-sided printing, print on this side first
(unless instructed otherwise in the operator guide for your laser
printer).
How you load preprinted paper is determined by the preprinting.
Preprinted forms should be produced so that their curl is
compatible with the requirements in your MICR printer operator
guide.
When you use perforated paper, your objective is to have a
smooth, free-feeding sheet that retains sufficient beam strength
to prevent sheet fold-over, buckling, or jams.
If you use preperforated forms, consider the following factors:
• Use 24 pound/90 gsm paper.
• Use a perforation that lets the sheets retain as much stiffness
as possible. Reduced stiffness may result in jamming and
paper mutilation.
• Perforations should be nine per inch.
• All holes should be the same size.
• The ratio of holes to paper (tie size) should be less than or
equal to 1:1. In other words, the tie size should be at least as
large as the hole size.
