Moisture content
Moisture content directly affects reliability and image quality.
• Too much moisture can cause excessive paper curl, paper
jams, and image quality problems. Moisture levels that are too
low can cause static problems, which can also result in paper
jams.
• Moisture content must be uniform within the ream. The ream
should not be allowed to lose or absorb moisture during
storage. Moisture-proof ream wrappers are essential to
maintaining the correct moisture level. Xerox papers have a
specially designed ream wrapper that resists the migration of
moisture into and out of the package.
• A moisture level range of 4.0 to 5.0% is recommended for
paper used in a copier/printer.
Electrical properties (conductivity and resistivity)
Paper that is highly conductive causes image deletion and paper
jams. Highly resistive paper, on the other hand, causes static build-
up between paper sheets, leading to multi-feeds, jams, and image
offset problems. Electrical properties should be balanced to prevent
deletions under humid conditions, or background (spots/streaks)
and static under dry conditions.
Xerox papers have the correct balance to provide you with optimum
performance.
Surface strength
For a paper to have acceptable surface strength, fibers and
chemicals must be bonded well to its surface. Loose fibers and other
materials within paper can cause developer contamination that can
further cause premature developer failure in Xerox printers/copiers.
