5. Margins: Margins should be 8 mm from the edge of the paper to the line.

Analyzing the Color Step Pages
This print consists of 4 pages, CMYK in graduated fills of decreasing density.
Things to look for:
■ Repeating defects or banding
■ Inconsistant variations in density
■ Streaks
■ Vo i d s
1. Graduated fills in each color. Each color should be consistent across the width of
the page with no voids.
2. No separation or misconvergence where each bar meets its neighbor. Each bar is
separated by a thin black line.
3. Look for thin white lines that would indicate a dirty LED lens or a scratched
Imaging Unit.
4. Look for dark lines that would indicate a dirty or damaged Imaging Unit.
5. Look for complete fusing. Cold or hot offset fusing could indicate the incorrect
paper weight has been selected.
