By examining each group, you can isolate the problem to a particular toner cartridge.

Section Toner cartridge
1 Yellow
2 Cyan
3 Black
4 Magenta
● If dots or streaks appear in only one of the groups, replace the toner cartridge that correlates with that
group.
● If dots appear in more than one group, print a cleaning page. If this does not solve the problem, determine
if the dots are always the same color; for example, if magenta dots appear in all five color bands. If the dots
are all the same color, replace that toner cartridge.
● If streaks appear in multiple color bands, contact HP. A component other than the toner cartridge is
probably causing the problem.
Check the EconoMode settings
HP does not recommend the full-time use of EconoMode. If EconoMode is used full-time, the toner supply might
outlast the mechanical parts in the toner cartridge. If print quality begins to degrade and is no longer acceptable,
consider replacing the toner cartridge.
NOTE: This feature is available with the PCL 6 print driver for Windows. If you are not using that driver, you can
enable the feature by using the HP Embedded Web Server.
