US 9,317,006 B2 · Laser print cartridge with removable paper cleaning assembly

Abstract

An improved laser print cartridge having a reduced defect rate. The improved laser print cartridge includes a printing assembly, a primary cleaning assembly, and a paper cleaning assembly. The printing assembly includes a drum, a primary charge roller, and a toner roller for applying toner to printer paper. The primary cleaning assembly includes a wiper blade for removing large debris particles from the drum into a large particle receiving volume. The paper cleaning assembly provides a wicking flange for removing smaller particles of debris not removed by the wiper blade. As such, the wicking flange is positioned in between the wiper blade and the primary charge roller and is mounted to the wiper blade. A cleaning portion of the wicking flange is pressed against the drum and either absorbs the debris or wipes the debris into a small particle receiving volume delineated by the drum, wicking flange, and wiper blade.
