Single brush cleaner with collection roll and ultrasonic cleaning assist

Abstract From the Canadian patent

An apparatus for efficient cleaning of the imaging surface. The primary cleaner is a rotating collection roll located directly opposite from andon the other side of the imaging surface from the ultrasonic cleaning assist device. The ultrasonic energy is used to remove the toner from the imaging surface enabling attraction toward the biased collection roll. The ultrasonic energy decreases the amount of residual toner remaining after transfer. The residual toner that is not cleaned from the surface by the collection roll is removed from the surface by the rotating biased conductive brush which is, the secondary cleaner. The collection roll is contactless in that it does not come into contact …
