16.2.7 MCYBk Horizontal Stripe (TYPE=10)

Use this test print to check the density of dark areas of individual colors, balance among colors, and white lines in
relation to development.
a. Solid Density of Colors and Balance Among Colors
- The density must not be appreciably low (light).
- If the density of a specific color is too low, suspect a fault in the developer, primary transfer roller, laser exposure
system, or high-voltage system used for that color.
b. White/Black Lines
If a white/black line occurs for a specific color, suspect a fault in the drum unit used for that color or dirt in the laser
optical path.
c. Uneven Density at the Front/Rear
If uneven density occurs for a specific color, suspect a fault in the drum unit, laser exposure system, or transfer
(intermediate/secondary) unit.
If uneven density occurs for all colors, suspect deterioration of the intermediate transfer unit.
