Increased gray background shading/printer wear Too heavy Use lighter paper, open the rear output tray. Excessive curl problems with feeding Too moist, wrong grain direction or short-grain construction Use long-grain paper. Jamming, damage to printer Cutouts or perforations Do not use paper with cutouts or perforations. Problems with feeding Ragged edges Use good quality paper. such as those used in some types of thermography. • Do not use raised or embossed letterhead. • The printer uses heat and pressure to fuse toner to the paper. Ensure that any colored paper or preprinted forms use inks that are compatible with this fusing temperature (180°C or 356°F for 0.1 second).

Ideally, the printer 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 in preventing 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 damage due to the environment, especially if they are not wrapped with a moisture-proof barrier. The paper storage environment should be properly maintained to ensure optimum printer 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 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. G.8 SPECIFICATIONS G G 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 90 g/m2 (24lb) or jamming may occur. • Construction: Prior to printing, envelopes should lie flat with less than 6 mm (0.25 in.) 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 printer. • Size: You should only use envelopes within the following size ranges. Minimum Maximum Multi-purpose 90 X 140 mm 216 X 356 mm Tray (3.5 X 5.5 in.) (8.5 X 14 in.) NOTES: • Use only the Multi-purpose Tray 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. Please refer to “Printer and Paper Storage Environment” on page G.8. SPECIFICATIONS G.9 Envelopes with Double Side Seams Double side-seams envelopes have vertical seams at both ends rather than diagonal seams. This style may be more likely to wrinkle. Be sure the seam extends all the way to the corner of the envelope as illustrated below. Correct Incorrect Envelopes ...
