Print-Quality Troubleshooting
Yellow Step
5-12
The Yellow Step page contains yellow in graduated fills of decreasing density.
Things to look for:
• Repeating defects or banding
• Inconsistent variations in density
• Streaks
• Voids
Each color should be consistent across the page with no voids.
No separation or misconvergence where each bar meets its neighbor. Each bar is
separated by a thin black line.
Look for thin white lines that would indicate a dirty LED lens or a scratched
Imaging Unit.
Look for dark lines that would indicate a dirty or damaged Imaging Unit.
Look for complete fusing. Cold or hot offset fusing could indicate the incorrect
paper weight has been selected.
