							Solve print-quality problems
You can prevent most print-quality problems by following these guidelines.
●Configure the trays for the correct paper-type setting. See 
Configure trays on page 54.
● Use paper that meets HP specifications. See 
Paper and print media on page 43
.
● Clean the product as necessary. See 
Clean the paper path on page 91
.
Print-quality problems  associated with paper
Some print-quality problems arise from using paper that does not meet HP specifications.
●The surface of the paper is too smooth.
● The moisture content of the paper is uneven, too high, or too low. Use paper from a different source
or from an unopened ream.
● Some areas of the paper reject toner. Use paper from a different source or from an unopened ream.
● The letterhead you are using is printed on rough paper. Use a smoother, xerographic paper. If this
solves your problem, ask the supplier of your letterhead to use paper that meets HP specifications.
● The paper is excessively rough. Use a smoother, xerographic paper.
● The paper is too heavy for the paper-type setting that you selected, so the toner is not fusing to
the paper.
For complete paper specifications for all HP LaserJet products, see the  HP LaserJet Printer Family Print
Media Guide . This guide is available at 
www.hp.com/support/ljpaperguide .
Print-quality problems associ ated with the environment
If the product is operating in excessively humid or dry conditions, verify that the printing environment is
within specifications. See 
Operating environment on page 146.
Print-quality problems associated with jams
Make sure that all sheets are cleared from the paper path.
●If the product recently jammed, print two to three pages to clean the paper path.
● If the sheets do not pass through the fuser and cause image defects on subsequent documents,
print two to three pages to clean the paper path. If the problem persists, print and process a cleaning
page. See 
Clean the paper path on page 91.
