Print-Quality Troubleshooting
Horizontal Bands, Voids Or Streaks in Any or All Colors
There are areas of the image that are extremely light or missing entirely.
These missing areas form bands parallel to the leading edge.
Initial Actions
■ Confirm that the paper is supported. Poor quality papers can contribute to
this type of problem.
■ Ask the customer about their typical printing habits. Continuously printing
long print jobs with heavy coverage can temporarily cause banding.
