HP Designjet 4000 Printer Series - Quick Reference Guide

The problem is banding (horizontal lines across the
image)
If your printed image suffers from added horizontal lines as shown (the color may vary):
1. Check that you are using appropriate print quality settings. See “How do I choose
print quality settings?” on page 68.
2. If the problem persists, clean the printheads. See “How do I recover (clean) the
printheads?” on page 51.
3. Consider changing to a heavier paper type: we recommend HP Heavyweight
Coated Paper or HP Productivity Photo Gloss when printing dense colors.
4. If the problem persists, use the Image Diagnostics Print to find out more about it.
See “How do I use the Image Diagnostics Print?” on page 113.
