Abstract
A cleaning apparatus for achieving a non-uniform load on the detoning roll to prolong the life of the detoning roll by preventing premature wear of the detoning roll ends. The uniform load on the scraper blade is prevented from wearing the detoning edges before the middle due to unequal toner distribution in the present invention. This results in a higher frictional force on the edges of the detoning roll than in the center. To prevent wearing of these edges, the ends of either the scraper blade or the scraper blade holder are angled away from the detoning roll enabling a desirable working load to be achieved at the center where sufficient toner can lubricate the blade edge without overloading the blade ends where toner collection is generally minimal. The present invention increases the scraper blade life and reduces detone roll wear without reducing cleaning performance.
