Abstract

The ground brush positioned in proximity to the photoreceptor has the tendency to collect toner and debris thereabout, which is accumulated from the rotation of the photoreceptor. Build up of dirt and toner at this ground strip may cause intermittent electrical connections which may affect copy quality, preventing a full image appearance. Furthermore, build-up of this type may also cause eventual wear of the ground brush strap, which is used to adhere the ground brush to the machine. As shown in the accompanying figure, locating one or more nylon strip brushes 2 in a horizontal position with respect to the photoreceptor 10 serves to hold back dirt and residual toner that otherwise tends to accumulate at the ground strap 4. Testing has shown that after a 50,000 print run having a nylon brush positioned with respect to the photoreceptor, the ground strip appeared very clean. The nylon brush is made of a relatively soft nylon material. Placement of two brushes in series with each other, and in front of the ground strip, may more effectively prevent build up at the ground strap.
