● Inspect the print media for obvious defects, such as torn sheets, contamination from glue, or ragged cut edges. ● Use print media from another lot or from a different manufacturer. NOTE: If a print problem develops when using certain print media, switch to a known good print media, preferably HP branded. ● Turn the paper stack over in the input tray and/or turn it 180° in the tray. Alternatively, try using another tray. ● If you have a print-quality problem that is related to envelopes, print a sheet of paper to determine if the problem is caused by the variable thickness of your envelope. - If the print quality of the single-sheet sample is good, re-examine your envelope and see Envelope construction on page 14. - If the print quality of the single-sheet sample is poor, you might have a printer problem. See the support documentation for your printer to see further troubleshooting information. ● Read the remainder of this troubleshooting section for further troubleshooting information, perform the maintenance procedures that are recommended in your printer user guide, or see the troubleshooting section in your printer user guide. Types of print media to avoid To ensure proper performance of your HP LaserJet printer, use paper or other print media specifically designed to work with your printer. Avoid using print media with the following characteristics: ● Print media, media coatings, dyes, or inks that contain materials that melt, vaporize, offset, discolor, or release undesirable emissions when exposed to 205°C (401°F) for 0.1 second (0.2 second for HP color LaserJet printers). ● Print media that is very rough, highly textured, or heavily embossed. ● Multipart forms. ● Carbonless media. ● Print media that offsets or discolors. ● Print media that is damaged, curled, wrinkled, or irregularly shaped. ● Print media that has not been stored or shipped properly. (See Shipping and storing print media on page 22.) ● Overhead transparency film that produces undesirable emissions or melts when exposed to a fusing temperature of 205°C (401°F) for 0.1 second (0.4 second for HP color LaserJet printers). An example would be overhead transparencies that are designed for printing on an ink printer. ● Envelopes that have encapsulated adhesives that do not require moistening but instead use pressure for sealing. ● Envelopes that have clasps, snaps, tie strings, windows, or synthetic materials. These materials can severely damage the printer. 26 Chapter 3 Troubleshooting print media problems ENWW
