Abstract

In electrophotographic printing, it is highly desirable to remove residual toner particles from the photoconductive surface after the toner powder image has been transferred to the copy sheet. As shown in the figure, a foam roller 10 is positioned in contact with photoconductive surface 12. A rotating roller 14 is interfit over a stationary magnet 16. Roller 14 engages foam roller 10. Filter 18 is disposed in the opening of housing 20. A blower system causes air to flow in the direction of arrow 22 outwardly from housing 20. This air flow removes the magnetic toner particles from roller 14. In this way, magnetic toner particles may be readily cleaned from photoconductive surface 12.

PHOTORECEPTOR CLEANING (Cont~d)

In electrophotographic printing, it is highly desirable to
remove residual toner particles from the photoconductive
surface after the toner powder image has been transferred to
the copy sheet. As shown in the figure, a foam roller 10 is
positioned in contact with photoconductive surface 12. A
rotating roller 14 is interfit over a stationary magnet 16.
Roller 14 engages foam roller 10. Filter 18 is disposed in the
opening of housing 20. A blower system causes air to flow in
the direction of arrow 22 outwardly from housing 20. This air
flow removes the magnetic toner particles from roller 14. In
this way, magnetic toner particles may be readily cleaned from
photoconductive surface 12.
