Printer and Paper Storage
Environment
Paper storage environmental conditions directly affect the feed
operation.
Ideally, the printer 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 printer 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:
• Paper should be stored at or near room temperature.
• The air should not be too dry or too humid.
• The best way to store an opened ream of paper is to
rewrap it tightly in its moisture-proof wrapping. If the
printer environment is subject to extremes, unwrap only
the amount of paper to be used during the day’s
operation to prevent unwanted moisture changes.
Envelopes
Envelope construction is critical. Envelope fold lines can vary
considerably, not only between manufacturers, but also within
a box from the same manufacturer. Successful printing on
envelopes depends upon the quality of the envelopes. When
selecting envelopes, consider the following components:
• Weight: The weight of the envelope paper should not
exceed 90 g/m
2
(24 lb) or jamming may occur.
• Construction: Prior to printing, envelopes should lie flat
with less than 6 mm (0.25 in) curl, and should not
contain air.
• Condition: Envelopes should not be wrinkled, nicked, or
otherwise damaged.
• Temperature: You should use envelopes that are
compatible with the heat and pressure of the printer.
• Size: You should only use envelopes within the following
size ranges.

OTES
:
• Use only the Multi-Purpose Tray to print envelopes.
• You may experience some paper jams when using any media
with a length less than 127 mm (5.0 in). This may be caused
by paper that has been affected by environmental
conditions. For optimum performance, make sure you are
storing and handling the paper correctly. Please refer to
“Printer and Paper Storage Environment” on page 10.4.
