Abstract

The present disclosure is directed to a spots blade positioned downstream from two cleaner brushes found in an electronic printing or copying machine. A spots blade is used 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 is incorporated into the machine as a secondary cleaning system so as to reduce the occurrence of agglomerate spots that would otherwise form on the prints or copies.

SPOTS BLADE COVER (Cont'd)

The present disclosure is directed to a spots blade positioned downstream from two cleaner brushes found in an electronic printing or copying machine. A spots blade is used 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 is incorporated into the machine as a secondary cleaning system so as to reduce the occurrence of agglomerate spots that would otherwise form on the prints or copies.

The spots blade is vulnerable to becoming dry and unlubricated causing motion quality defects which are the result of blade bounce. Thus, a spots blade cover is proposed to trap a small amount of toner, at the blade tip, and provide a continuous supply of lubrication.

Referring to the accompanying figure, there is shown a spots blade 14
positioned downstream from two cleaning brushes 11 and 13 so as engage photoreceptor 18 moving in the direction of arrow 22. Spots blade 14 partially cleans photoreceptor 18 by collecting toner particles 20 at the blade tip. Spots blade 14 is clean...
