An ECOSYS III printer has streaks or fine lines appearing on the printed output after a service clean has been performed. This can be caused by hairs or lines on the Developer application roller, identified in the User Manual.


The developer needs to be removed and the developer roller cleaned. Use a lint free cloth - provided with each Toner Kit.

Be sure to check for fine fibres and hairs on the developer roller surface.

Caution: Do not touch the developer roller with your fingers or knock with heavy objects as this can leave marks on prints.
