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 90g/m2 (24lb) or jamming may occur. • Construction: Prior to printing, envelopes should lie flat with less than 6mm (0.25in.) 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. Multipurpose tray Minimum 76 x 127 mm (3 x 5 in.) Maximum 216 x 356 mm (8.5 x 14 in.) NOTES: • Use only the manual feeder to print envelopes. • You may experience some paper jams when using any media with a length less than 140 mm (5.5 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.
