Troubleshooting Print Quality Problems
Shown below is an example of what you might see if you have problems
with the paper not being flat:
Corrective Action
1 Check that the paper type loaded corresponds to the paper type selected in
the front panel and in the software. You can verify the paper type selected
through the Front Panel (Main Menu/Paper menu/View loaded paper).
2 Try using a heavier paper type. When printing dense colors, it is
recommended to use HP Heavyweight Coated Paper HP Super,
Heavyweight Coated Paper or thicker Digital Fine Art papers.
3 Check that the environmental conditions (temperature, humidity) are within
the temperature/humidity range as specified for the Printer (refer to the
User’s Guide for further information).
4 Select a paper type that is slightly thinner than the paper you have loaded;
this will persuade the printer to use less ink. Here are some example paper
types in ascending order of thickness:
 Plain Paper
 Coated Paper
 Heavyweight Coated Paper
 Fine Art Paper
 Super Heavyweight Plus Matte Paper
 Thick Fine Art Paper (>250 g/m²).
If your paper type has different versions in the front panel with more and less
ink, select the one with less ink.
