Print media that does not meet the guidelines outlined in this manual can cause the following problems:. To download the guide in PDF format, go to www. Ideally, the printing and media-storage environment should be at or near room temperature, and not too dry or too 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 distort. This issue can cause jams. As a result, paper storage and handling are as important as the paper-making process itself.

Paper storage environmental conditions directly affect the feed operation and print quality. Care should be taken not to purchase more paper than can be easily used in a short time about three months. Paper stored for long periods can experience heat and moisture extremes, which can cause damage.

Planning is important to prevent damage to a large supply of paper. Unopened paper in sealed reams can remain stable for several months before use. Opened packages of paper have more potential for environmental damage, especially if they are not wrapped with a moisture-proof barrier. The media-storage environment should be properly maintained to ensure optimum printer performance. The following guidelines should be helpful when evaluating the storage environment:.

If the printer environment is subject to extremes, unwrap only the amount of paper to be used to prevent unwanted moisture changes. Use only tray 1 to print on envelopes. Select the type of envelope that you are using from the Print dialog box or the printer driver. In your program, set the margins for the envelope.

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:. Double side-seam construction has vertical seams at both ends of the envelope rather than diagonal seams. This style might be more likely to wrinkle. Be sure the seam extends all the way to the corner of the envelope as shown in the illustration. Envelopes with a peel-off adhesive strip or with more than one flap that folds over to seal.
