15.5 Paper Grain and Curl

Paper grain and curl can dramatically affect the reliability of machines that use an
electrostatic process, like the imagePRESS V900/V800/V700. It is recommended to
use paper that is cut for long edge feeding (electrostatic paper). The composition of
electrostatic paper produces better quality results in a digital machine. Therefore,
when selecting paper for the imagePRESS V900/V800/V700, select paper intended
for use in electrostatic machines, such as laser printers and copiers.
If paper jams or poor print quality occur when paper is fed from the multi-purpose
tray or optional paper deck, paper curl is often the cause. The paper stiffness,
direction of curl, and amount of curl has 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
the feeding direction of the paper.
• For more information on the correct direction to load paper, check the label on the
paper package.
