Possible cause

Any of the following can cause this defect:

  • Contamination of the laser lens
  • Transfer Belt scratches/creases
  • Toner dust or moisture build-up on the Transfer Belt cleaner blade
  • Fuser exit rear end memory



Suggested remedy

The printer has several built-in self-cleaning methods. They include the laser lens cleaner, corona wire cleaner, and discharge brushes. Clean these items frequently and make sure their maintenance has been conducted at the proper intervals. The procedure laid out below describes the proper methods for cleaning the corona wire charger and the printhead lens.

In addition, the Transfer Belt life is 300K pages and it will exhibit this problem when it’s at its end of life. To know more about this, see the sections "Estimated number of remaining pages" and "Ordering a 300K maintenance kit" in your printer's User's Guide.

If defect persists, please contact Lexmark Technical Support for additional troubleshooting suggestions.
