Paper Grain And Curl - Canon Oce VarioPrint 6000 Ultra+ Series Manual

15.7 Paper Grain and Curl

Paper grain and curl can dramatically affect the reliability of the Océ VarioPrint
6000+ Series machines.
If paper jams or poor print quality occur when paper is fed from the Paper Input
Modules, paper curl is often the cause. The paper stiffness, direction of curl, and
amount of curl have a strong influence on how well the paper is transported
through the machine. If paper is curled, straighten out the paper by gently curling it
in the opposite direction to which it is curled.
Paper stiffness depends on the direction of the paper grain. Paper tends to curl in
the direction parallel to the grain.
IMPORTANT
• When using LTR or smaller paper sizes we recommend using paper with a grain
parallel to the long edge (A). For paper sizes larger than 11" x 17", we
recommend using paper with a grain parallel to the short edge (B). When using
coated paper thinner than 105 g/m
perpendicular to the feeding direction of the paper.
• If 12 point, 243 g/m
paper that is cross-grained. Thick, long grain paper does not fold as easily.
Cross-grained paper is more flexible, resulting in a smoother crease along the
direction of the fold.
