Media storage environment
Media storage environmental conditions directly affect the feed operation.
Note Do not purchase more media than can be easily used in a short time (about 3 months). Media
stored for long periods experiences heat and moisture extremes that can be damaging. Planning
is important to prevent damage to a large supply of media.
Hewlett-Packard neither warrants nor recommends the use of a particular brand of paper or print
media. Media properties are subject to manufacturing changes Hewllett-Packard has no control
over such changes. The customer assumes all responsibility for the quality and performance of
media. Although testing media helps to characterize its performance, process quality control by
the manufacturer.
Unconverted media in sealed reams can remain stable for several months before use. Converted
media has greater potential for environmental damage, especially if it is not wrapped with a
moisture-proof barrier.
The media storage environment should be maintained to ensure optimum printer performance.
The required condition is 20 degrees to 24 degrees C (68 degrees to 75 degrees F), with a
relative humidity of 45 percent to 55 percent. The following guidelines should be considered
when evaluating the customer’s media storage environment:
● Media 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 media
to be used during the day’s operation to prevent unwanted moisture changes.
