General guidelines Some print media might meet all of the guidelines in this manual and still not produce satisfactory results. This problem might be the result of improper handling, unacceptable temperature and humidity levels, or other variables over which HP has no control. Before purchasing large quantities of print media, always test a sample and make sure the that the print media meets the requirements specified in the HP Color LaserJet 2550 Series Printer User Guide and in the HP LaserJet Printer Family Print Media Guide. For ordering information, see Ordering parts and supplies. CAUTION Using print media that does not meet HP specifications can cause problems for the printer, requiring repair. This repair is not covered by the HP warranty or service agreements. 18 Chapter 1 Product information ENWW This printer accepts a variety of media, such as cut-sheet paper (including up to 100% recycled-fiber-content paper), envelopes, labels, transparencies, glossy paper, HP LaserJet Tough paper, and custom-size paper. Properties such as weight, composition, grain, and moisture content are important factors affecting printer performance and output quality. Print media that does not meet the guidelines outlined in this manual can cause the following problems: Poor print quality Increased jams Premature wear on the printer, requiring repair Paper and print media Category Acid content Caliper Curl in ream Cut-edge conditions Fusing compatibility Specifications 5.5 pH to 8.0 pH 0.094 to 0.18 mm (3.0 to 7.0 mils) Flat within 5 mm (0.02 inch) Cut with sharp blades with no visible fray Must not scorch, melt, offset, or release hazardous emissions when heated to 210°C (410°F) for 0.1 second Long Grain 4% to 6% by weight 100 to 250 Sheffield Grain Moisture content Smoothness For complete print-media specifications for all HP LaserJet printers, see the HP LaserJet Printer Family Print Media Guide. To download the guide in PDF format, go to www.hp.com/ support/ljpaperguide. Printing and storage environment 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. ENWW Media specifications 19 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 required condition is 20° to 24°C (68° to 75°F), with a relative humidity of 45% to 55%. The following guidelines should be helpful when evaluating the storage environment: Print media should be stored at or near room temperature. The air should not be too dry or too humid (to moderate the hygroscopic properties of paper). The best way to store an opened ream of paper is to rewrap it tightly in its moistureproof wrapping. If the printer environment is subject to extremes, unwrap only the amount of paper to be used to prevent unwanted moisture changes. Avoid storing paper and print media near heating and air conditioning vents or near windows and doors that are frequently open. Envelopes 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. The following table gives typical address margins for a commercial #10 or DL envelope. Type of address Return address Delivery address Top margin 15 mm (0.6 inch) 51 mm (2 inches) Left margin 15 mm (0.6 inch) 89 mm (3.5 inches) For the best print quality, position margins no closer than 15 mm (0.6 inch) from the edges of the envelope. Avoid printing over the area where the envelope seams meet. Envelope storage Proper storage of envelopes helps contribute to print quality. Envelopes should be stored flat. If air is trapped in an envelope and creates an air bubble, then the envelope might wrinkle during printing. For more information, see Resetting the printer for non-HP supplies. Envelope construction 20 Chapter 1 Product information ENWW 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 (24 lb) or jamming might occur. Construction: Before printing, envelopes should lie flat with less than 6 mm (0.25 inch) curl, and should not contain air. Condition: Envelopes should not be wrinkled, nicked, or otherwise damaged. Temperature: Use envelopes that are compatible with the heat and pressure of the printer. The fusing temperature of this printer is 210°C (410°F). Size: Use only envelopes that are within the following size ranges. Minimum: 6 x 127 mm (3 x 5 inches) Maximum: 216 x 356 mm (8.5 x 14 inches) Envelopes with double side-seams 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. 1 2 1 2 acceptable unacceptable Envelopes with adhesive strips or flaps Envelopes with a peel-off adhesive strip or with more than one flap that folds over to seal must use adhesives that are compatible with the heat and pressure in the printer. The extra flaps and strips might cause wrinkling, creasing, or even jams and might damage the fuser. Labels Select the type of label that you are using from the Print dialog box or the printer driver. CAUTION To avoid damaging the printer, use only labels that are recommended for laser printers. To prevent serious jams, always use tray 1 to print on labels and always use the straightthrough paper path. Never print on the same sheet of labels more than once or print on a partial sheet of labels. ENWW Media specifications 21 When selecting labels, consider the quality of each component: Adhesives: The adhesive material should be stable at 210°C (410°F), which is the printer fusing temperature. Arrangement: Only use labels with no exposed backing between them. Labels can peel off sheets with spaces between the labels, causing serious jams. Curl: Before 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 have wrinkles, bubbles, or other indications of separation. For more information, see Imaging drum. Transparencies Use only tray 1 to print on transparencies. Select Transparencies from the Print dialog box or the printer driver. The printer supports printing in color on transparencies. Transparencies that are used in the printer must be able to withstand 210°C (410°F), which is the printer fusing temperature. CAUTION To avoid damage to the printer, use only transparencies that are recommended for use in laser printers. For more information, see Media specifications. 22 Chapter 1 Product information ENWW Hewlett-Packard limited warranty statement HP PRODUCT HP color LaserJet 2550L, 2550Ln, 2550n DURATION OF LIMITED WARRANTY 1 year, Return to Authorized Service Center HP warrants to you, the end-user customer, that HP hardware and accessories will be free from defects in materials and workmanship after the date of purchase, for the period specified above.
