Problem
Smears, Smudges, and Streaks
Dark or light marks appear on your
output.
Stray black dots or white areas
(dropouts).
Repeating Spots or Lines
Spot or lines appear at regular intervals
on the prints.
Solution
Run several blank pages through the printer to remove toner
accumulated on the fuser.
If the problem persists, print a Calibration Chart to determine which
component is causing the image-quality problem. To print the
Calibration Chart, on the control panel, select Menu > Admin Menu >
Image Quality > Adjust Gradation > Photo > Calibration Chart. Then
follow the onscreen instructions.
• If the defect occurs in one color only, replace the corresponding
imaging unit.
• If the defect occurs in all colors and is visible on the test page,
replace the fuser.
1. Replace the paper with a recommended size and type, and confirm
that your control panel and print driver settings are correct. For
details, see Supported Paper
2. Verify that the toner cartridges meet specifications and replace them
if necessary. For details, see
To determine the cause, print full pages of the primary colors: cyan,
magenta, yellow, and black (CMYK). Then measure the distance between
the print defects.
• Imaging Unit 94 mm (3.7 in.), 38 mm (1.5 in.), or 31 mm (1.2 in.)
• Fuser 94 mm (3.7 in.), 83 mm (3.3 in.), or 44 mm (1.7 in.)
• Transfer Roller 68 mm (2.7 in.)
If the repeating defects match one of these distances, replace that item.
