Abstract

A photoreceptor pumicing apparatus 1 and method is contem~ plated wherein a photoreceptor surface of a xerographic machine 2 may be pumiced as frequently as desired without removing the photoreceptor drum from the machine, This is accomplished by applying a dry pumicing sheet 3 to the photoreceptor surface from the copy paper feed station and by electrostatically tacking the sheet to the photoreceptor surface while rotating the drum.

A photoreceptor pumicing apparatus 1 and method is contem~
plated wherein a photoreceptor surface of a xerographic
machine 2 may be pumiced as frequently as desired without
removing the photoreceptor drum from the machine, This is
accomplished by applying a dry pumicing sheet 3 to the
photoreceptor surface from the copy paper feed station and
by electrostatically tacking the sheet to the photoreceptor
surface while rotating the drum.

A sheet of dry pumice material 3 is loaded into the copy
paper tray on top of the paper stack, The rear end of the
sheet is mechanically attached to the feed tray by fasten~
ing it over a lip on the tray. The machine 2 is then
cycled. The pumice sheet 3 is fed by rolls 4 and 5 to the
drum 6 just like a sheet of copy paper, until it is advan~-
ced its full length. Since the trail edge of the sheet 3
is secured to the paper supply tray, the sheet remains
stationary while the drum 6 continues to rotate, The trans~
fer corona generator 7 is energized to electrostatically
tack the pumice sheet 3 to the photoreceptor surface in the
transfer zone, The combination of electrostatic tacking
force and the pumice sheet roughness and beam strength as
well as the number of drum revolutions determine the amount
of pumicing of the photoreceptor surface, After the pumic~
ing operation is completed, the pumi...
