Troubleshooting print-quality problems

This section helps you define print-quality problems and what to do to correct them. Often print- quality problems can be handled easily by making sure that the printer is correctly maintained, using print media that meets HP specifications, or running a cleaning page.

Print-quality problems associated with media

Some print-quality problems arise from the use of inappropriate media.

●Use media that meets HP specifications. See Paper specifications.

●The surface of the media is too smooth. Use media that meets HP specifications. See Paper specifications.

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

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

●The letterhead you are using is printed on rough media. Use a smoother, xerographic media. If this solves your problem, ask the supplier of your letterhead to use media that meets the specifications for this printer. See Paper specifications.

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

●The driver setting is incorrect. To change the media type setting, see Type and Size.

●The media that you are using is too heavy for the media type setting that you selected, and the toner is not fusing to the media.

Print-quality problems associated with the environment

If the printer is operating in excessively humid or dry conditions, verify that the printing environment is within specifications. See the printer getting started guide for operating-environment specifications.

Print-quality problems associated with jams

Make sure that all sheets are cleared from the paper path. See Jam recovery.

●If the printer recently jammed, print two to three pages to clean the printer.

●If the sheets do not pass through the fuser and cause image defects on subsequent documents, print three pages to clean the printer. If the problem persists, print and process a cleaning page. See Cleaning the printer.
