Note Table 2-3. Common media problems (continued) Symptom Problem with paper Jamming, or damage to printer. Cutouts or perforations. Problems with feeding. Ragged edges. Solution Do not use media that has cutouts or perforations. Use good-quality media. Labels For best results, use only HP-brand labels. To order HP supplies, visit http://www.hp.com. When selecting labels, consider the following factors: ● Adhesives: The adhesive material should be stable at 200° C (392° F), the product's maximum temperature. ● Arrangement: Use only labels that have no exposed backing between them. Labels can peel off sheets that have spaces between the labels, causing serious jams. ● Curl: Prior to printing, labels must lie flat with no more than 13 mm (0.5 inch) of curl in any direction. ● Condition: Do not use labels that contain wrinkles, bubbles, or other indications of separation. Never use a sheet of labels that has already been run through the printer. 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 on the quality of the envelopes. When selecting envelopes, consider the following factors: ● Weight: The weight of the envelope paper should not exceed 105 g/m2 (28 lb), or jamming might result. ● Construction: Before printing, envelopes should lie flat with less than 6 mm (0.25 inch) curl and should not contain air. Envelopes that trap air can cause problems. ● Condition: Make sure that the envelopes are not wrinkled, nicked, or otherwise damaged. ● Sizes: Supported envelope sizes range from 90 by 160 mm (3.5 by 6.3 inches) to 178 by 254 mm (7 by 10 inches). Store envelopes flat. If air is trapped in an envelope, creating an air bubble, the envelope might wrinkle during printing. ENWW Guidelines for using media 37
