Interpret the Print Quality Page

2. Load paper in the input tray.
3. In the Windows system tray, right-click the Device Settings icon and then click the product name.
4. Click the Device Settings button.
5. Click the Print PQ Troubleshooting Page button.
This page contains ve 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 print cartridge.
Section Print-cartridge
1 Yellow
2 Cyan
3 Black
4 Magenta
●
If dots or streaks appear in only one of the groups, replace the print 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 ar
e always the same color; for example, if magenta dots appear in all ve color
bands. If the dots are all the same color, replace that print cartridge.
●
If streaks appear in multiple color bands, print a supplies status page to determine if the imaging drum
has re
ached its estimated end of life. If imaging drum has not reached its estimated end of life, inspect
the imaging drum for damage. If the imaging drum is not damaged, contact HP.
Inspect the print cartridge and imaging drum for damage
1. Remove the print cartridge from the product, and examine for damage.
2. If the print car
tridge does not appear to be damaged, rock the print cartridge gently several times and
reinstall it. Print a few pages to see if the problem is resolved.
