Abstract

Blade cleaning mechanisms cause a pile of toner and contaminants to accumulate on the photoreceptor at the tip of the blade. If the blade contacts the photoreceptor in the same location both before and after retraction, contaminants such as paper fibers become trapped resulting in streaking of the final copies.

SPRING BIASED CLEANING BLADE FOR REMOVING RESIDUAL TONER FROM A CHARGE RETENTIVE SURFACE(Cont'd)

Blade cleaning mechanisms cause a pile of toner and contaminants to accumulate on the photoreceptor at the tip of the blade. If the blade contacts the photoreceptor in the same location both before and after retraction, contaminants such as paper fibers become trapped resulting in streaking of the final copies.

To avoid the aforementioned problem, a bias spring 10 is provided which transfers the mechanical attitude or alignment of the cleaning blade holder assembly 14 so that the cleaning blade 16 contacts the photoreceptor drum at some predetermined point 20 (see Figure 1) above the toner pile when the blade reengages the drum. A counterweight 18 applies pressure to the blade so that it slides down the photoreceptor until it is located at the cleaning position indicated at 22 shown in Figure 2. As can be seen from a comparison of...
