Print quality troubleshooting

When occasional print quality problems occur, use the information in this section to help solve the problem.

Print quality problems associated with media

Some print quality problems arise from use of inappropriate media.

●Use paper that meets HP paper specifications. See Supported media weights and sizes.

●The surface of the media is too smooth. Use media that meets HP paper specifications. See Supported media weights and sizes.

●The print driver setting might be incorrect. Be sure that you have selected the correct driver setting for the paper that you are using.

●The print mode might be set incorrectly, or the paper might not meet recommended specifications. For more information, see Supported media weights and sizes.

●The transparencies you are using are not designed for proper toner adhesion. Use only transparencies designed for HP Color LaserJet printers.

●The moisture content of the paper is uneven, too high, or too low. Use paper from a different source or from an unopened ream of paper.

●Some areas of the paper reject toner. Use paper from a different source or from an unopened ream of paper.

●The letterhead you are using is printed on rough paper. Use a smoother, xerographic paper. If this solves your problem, consult with the printer of your letterhead to verify that the paper used meets the specifications for this printer. See Supported media weights and sizes.

●The paper is excessively rough. Use a smoother, xerographic paper.

Overhead transparency defects

Overhead transparencies might display any of the image quality problems that any other type of media could display, as well as defects specific to transparencies. In addition, because transparencies are pliable while in the print path, they are subject to being marked by the media-handling components.

NOTE Allow transparencies to cool at least 30 seconds before handling them.

●On the printer driver’s Paper tab, select Transparency as the media type. Also, make sure that the tray is correctly configured for transparencies.

●Check that the transparencies meet the specifications for this printer. See Supported media weights and sizes.

For ordering information, see Part numbers.

●Handle transparencies by the edges. Skin oil on the surface of transparencies can cause spots and smudges.

●Small, random dark areas on the trailing edge of solid fill pages might be caused by transparencies sticking together in the output bin. Try printing the job in smaller batches.
