Abstract

One of the problems occurring in cleaning systems of a xerographic machine is the difficulty of removing the toner particles from the cleaning brush. Traditionally, flicker bars, vacuum cleaners and air knives were used for the purpose of removing toner particles from the brush. Here, ultrasonic energy is used to improve the particle removal process.

IMPROVED BRUSH CLEANING (Cont~d)

One of the problems occurring in cleaning systems of a xerographic machine is the difficulty of removing the toner particles from the cleaning brush. Traditionally,

flicker bars, vacuum cleaners and air knives were used for the purpose of removing toner particles from the brush. Here, ultrasonic energy is used to improve the particle removal process.

In Figure 1, an ultrasonic transducer 8 is mounted axially with cleaning brush 7 for rotation in unison therewith. Excitation for transducer 8 is supplied through slip ring 9. The axial vibration that results is transmitted through the brush core to the brush fibers 10 to aid in the removal of toner particles from brush 7.

In Figure 2, a flicker bar 12 is supported by springs 13. Ultrasonic transducer 14 is mounted on flicker bar 12. On energization of transducer 14, the resulting vibration of flicker bar 12 aids in the removal of toner particles from the brush 7.
