[. . . ] (For example, when duplexing on the HP color LaserJet 8500 printer, 90 g/m2 to 105 g/m2 [24 lb to 28 lb] media is recommended. ) CAUTION Duplexing on adhesive labels, envelopes, or overhead transparencies can damage your printer. Manual duplexing Manual duplex printing, in which sheets that already have been printed are fed again into the printer, requires operator intervention. (See the software application support documentation for more information. ) Hewlett-Packard recommends manually refeeding sheets only through the manual feed slot, the multipurpose (MP) tray, or tray 1. Do not refeed sheets from the paper cassette trays. Using the paper cassette trays can cause jams, misfeeds, and print-quality problems. Preparing laser-printed mailings Laser printing technology is being used by more and more postal customers to prepare mailings. Laser printers produce high-quality images; offer advantages in speed, flexibility, and size; and are the printers of choice for smaller companies and in-home businesses. Unlike offset printers, in which the ink is absorbed into the paper, laser printers use heat to fuse a plastic toner to the surface of the paper. Because of this difference, HP recommends that you use the following guidelines to produce quality laser-printed products for mailings: 1 Ensure that the manufacturer's recommended toner is used for the laser printer. Many aftermarket toners do not comply with the manufacturer's original specifications. Hewlett-Packard cannot predict or guarantee the performance of non-HP consumables in HP products. Several manufacturers have papers that are specifically formulated for their printers. For specific properties that are required for the paper used for laser-printed mailings, please contact your United States Postal Service business office. Do not store printed documents in vinyl folders (which can contain plasticizers) and do not expose the documents to petroleum-based solvents. q q q q q q q q q Environmental considerations HP LaserJet printers are designed to operate in a wide range of environmental conditions. For best performance, store and use media at 20° to 24° C (68° to 75° F), with a relative humidity of 45 to 55 percent. Follow these guidelines when media is used in an environment outside those temperature and humidity ranges: q Do not expose the media to extremes in humidity or temperature. If media is left unwrapped or in the printer input tray, extreme changes in the environment will cause the media to assume unwanted characteristics. In the case of extreme humidity, keep paper and envelopes tightly wrapped in plastic. q If a significant temperature difference exists between the media storage area and the printer's operating environment, allow the media time to adjust to the temperature in the printer's operating environment before unwrapping it. The greater the temperature difference and the greater the amount of media to acclimate, the longer this time period should be. Allow one day for every 10° C (20° F) difference in temperature between the storage environment and the printing environment. 2 Guidelines for using media 19 20 Shipping and storing print media ENWW 3 Troubleshooting Print-quality and media-handling problems usually result from print media that does not meet the specifications that are described in this guide, or print media that has been stored improperly or is not in good condition. The following sections further explain the possible causes of and solutions to print-media problems. Troubleshooting checklist Ask the following questions to determine if the print media is causing print-quality problems: Does your media meet the specifications outlined in this document?(See "Types of print media to avoid" on page 22 and "Guidelines for using media" on page 3. ) Is the media in good condition? Are you using the printing procedures that are described in the printer user guide? Are you observing correct practices when handling and loading media?
