For reliable digital press operation and good print quality, Xerox recommends the
following:
• Store Paper:
• On a flat surface. Do not store paper directly on the floor, since that
increases the possibility of moisture absorption. Paper should be stored
on pallets, or shelves or in cabinets in an area protected from extremes
of temperature and humidity.
• In a low dust area.
• In a low humidity area. Humidity is one of the most important steps to
promote proper paper characteristics. Optimum paper storage
conditions include a relative humidity of 35% to 55%. An increase in
humidity can cause paper to develop wavy edges. This occurs because
the edges absorb moisture while the rest of the ream remains
unaffected. Wavy edges can cause jams and misfeeds.
• In an air-tight moisture proof container.
• In controlled temperature. The temperature in the room where paper is
stored can have a significant effect on how that paper performs in the
machine. Optimum paper storage temperature is 68 to 76 degrees F (20
to 24.4 degrees C).
For additional paper handling information, refer to the Color Materials Usage
Guide.
• Cutting and Trimming Paper
Proper cutting of the paper is important. Mills offering paper in cut sizes cut
their papers using state-of-the-art rotary slitters on high performance
systems. Slitting and edge trimming by circular knives with dust removal at
every cutting point prevents contamination of the paper.
Trimming papers from parent sheets to get the desired output size may
generate dust if dull knives are used. The recommendation is to delay
trimming until printing has been finalized to prevent paper dust generation
and contamination.
If pre-printing is imperative, an in-house maintenance program, including
knife sharpness maintenance and dust removal with a vacuum or air system,
are key to achieving good results.
