Image defects

Overview
This chapter provides illustrations of image defects, lists suspected
causes, and offers suggested remedies
Using a Cleaning Page
For any print-quality defects, try using HP LaserJet Cleaning Utility to
generate a cleaning page. The HP LaserJet Cleaning Utility is designed
to remove excess paper and toner particles that can accumulate on the
fusing assembly rollers. The buildup of toner/paper dust results in
random spots on the front and back of the printout. Running the HP
LaserJet Cleaning Utility at regular intervals can extend the useful life of
the fuser and reduce service procedures. The HP LaserJet Cleaning
Utility works on all HP monochrome printers, regardless of driver type.
To download the HP LaserJet Cleaning Utility file and obtain
instructions on using it, access the HP website at
