Paper Storage Environment
Paper storage environmental conditions directly affect the feed operation.
Ideally, the machine and paper storage environment should be at or near room
temperature, and not too dry or humid. Remember that paper is hygroscopic;
it absorbs and loses moisture rapidly.
Heat works with humidity to damage paper. Heat causes the moisture in paper
to evaporate, while cold causes it to condense on the sheets. Heating systems
and air conditioners remove most of the humidity from a room. As paper is
opened and used, it loses moisture, causing streaks and smudging. Humid
weather or water coolers can cause the humidity to increase in a room. As
paper is opened and used it absorbs any excess moisture, causing light print
and dropouts. Also, as paper loses and gains moisture it can become
distorted. This can cause paper jams.
Care should be taken not to purchase more paper than can be used in a short
time (about 3 months). Paper stored for long periods may experience heat and
moisture extremes, which can cause damage. Planning is important to
prevent damage to large supplies of paper.
Unopened paper in sealed reams can remain stable for several months before
use. Opened packages of paper have more potential for environment
damage, especially if they are not wrapped with a moisture-proof barrier.
The paper storage environment should be properly maintained to ensure
optimum performance. The required condition is 20 to 24 °C (68 to 75 °F), with
a relative humidity of 45 % to 55 %. The following guidelines should be
considered when evaluating the paper’s storage environment:
Curl in ream Flat within 0.02 in. (5 mm)
Cut edge conditions Cut with sharp blades with no visible fray.
Fusing compatibility Must not scorch, melt, offset or release
hazardous emissions when heated to 200 °C
(392 °F) for 0.1 second.
