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:
• 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 
machine 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 20 lb (75 g/m
2
 
bond
) or jamming may occur.
• Construction: Prior to printing, envelopes should lie flat 
with less than 0.25 in. (6 mm) 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 machine.
• Size: You should only use envelopes within the following 
size ranges.

OTES
:
• Load only one sheet of paper at a time to print envelopes.
• You may experience some paper jams when using any media 
with a length less than 5.5 in. (140 mm). 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
