Abstract
The present application is directed to methods of operating a multi-color image forming device in a mono-color mode. The methods may include performing three basic loops during the printing in the mono-color mode. A first loop may include printing mono-color pages up to an initial preset maximum. The preset maximum may prevent a wear mark from forming on the non-operational PC members due to rubbing against the moving ITM. A second loop may occur when the mono-color pages exceeds the initial preset maximum. The second loop may include rotating the non-operational imaging stations to prevent wear. A third loop may occur when the number of mono-color images exceeds an overall maximum number. The third loop may include resetting the non-operational image forming stations to allow for continuing printing in the mono-color mode.
