Paper Spotted with Toner

Paper has toner spots of 0.5–1 mm (0.02–0.04 inches) in diameter.

Cause:

Toner fragments have slipped through the cleaning web, which cleans the pressure roller, and re-adhered to paper.

This may occur if:

• Printing on both sides of paper
• Printing on uncoated (especially rough-textured) paper
• Printing a single-dot halftone image

Solution:

Increasing the temperature when using thin paper with a thickness equivalent to Paper Weight 0 or 1 may cause paper curling, resulting in paper jams at the fusing unit.
