HP Color LaserJet Pro MFP M476 series - Manual (Page 118)

Print and interpret the print quality page
1. From the Home screen, touch the Setup button.
2. Touch the Reports button.
3. Touch the Print Quality Page button.
This page contains five bands of color, which are divided into four groups as indicated in the following
illustration. 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.
