Problem Solution
Smears, Smudges, and Streaks
Dark or light marks appear on your output.
Run a print job consisting of several blank pages
through the printer to remove toner accumulated on
the fuser.
If the problem persists, print the test pages to help
determine which component is causing the image-
quality problem.
• If the defect occurs in one color only, replace the
corresponding imaging unit.
• If the defect occurs in all colors and is visible on
all the test pages, replace the fuser.
