Toner or lubricant powder sticking to and accumulating on the surface of the drum are causing white stripes in images.
Cause:
The lubricant powder designed to lubricate the surface of the drum can deteriorate over time, especially with continuous high quality printing. This can allow toner to stick to and collect on the drum surface, leading to parallel white streaks at intervals of about 314 mm (12.5”). Common causes include:
- Continuous high-quality printing
- Worn drum cleaning unit
Solution:
- Wipe the surface of the drum clean with a dry, clean cloth.
