The paper storage environment should be properly maintained to ensure optimum performance. The
required condition is 20° C to 24° C (68° F to 75° F), with a relative humidity of 4 percent to 55percent. 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.
