Abstract

The present disclosure is directed to a spots blade positioned between two cleaner brushes in a retracting dual electrostatic brush cleaner found in an electronic printing or copying machine. A spots blade is found to be useful in these machines to clean mild adhesive material and other debris which tends to agglomerate and adhere to the photoreceptor surface. These agglomerate particles are often not effectively cleaned by the primary cleaning system of the machine. A spots blade incorporated into the machine as a secondary cleaning system, tends to reduce the occurrence of agglomerate spots that would otherwise form on the prints or copies produced by the machine due to the presence of this debris.

SPOTS BLADE POSITIONED BETWEEN MULTIPLE CLEANING BRUSHES (Cont'd)

The present disclosure is directed to a spots blade positioned between two cleaner brushes in a retracting dual electrostatic brush cleaner found in an electronic printing or copying machine. A spots blade is found to be useful in these machines to clean mild adhesive material and other debris which tends to agglomerate and adhere to the photoreceptor surface. These agglomerate particles are often not effectively cleaned by the primary cleaning system of the machine. A spots blade incorporated into the machine as a secondary cleaning system, tends to reduce the occurrence of agglomerate spots that would otherwise form on the prints or copies produced by the machine due to the presence of this debris.

Proposed, as shown in Figure 1, is to position the retractable spots blade 2 between the two cleaner brushes 4 and 6. The timing of the cleaning elements is such that the second brush 6 in the direction 10 of the movement of
photoreceptor belt 8 remains in cleaning engagement with the photoreceptor surface after the first brush 4 and spots blade 2 ar...
