Abstract
A cleaning solution is used to at least substantially remove colorant from the photoconductive drum as the photoconductive drum rotates. A wiper wipes the cleaning solution from the photoconductive drum while purposefully maintaining a layer of the cleaning solution on the drum. The wiper has an edge that is purposefully rounded.
Claims15
A cleaning assembly for a photoconductive drum of an electrophotographic printing device, comprising:
- a sponge impregnated with a cleaning solution to at least substantially remove colorant from the photoconductive drum as the photoconductive drum rotates past the sponge;
- and
- a wiper having an edge that is purposefully rounded to wipe the cleaning solution from the photoconductive drum.
An electrophotographic printing device comprising:
- a photoconductive cylinder;
- a cleaning mechanism to at least substantially remove colorant from the photoconductive cylinder as the photoconductive cylinder rotates past the cleaning mechanism by using a cleaning fluid;
- and
- a wiping mechanism positioned after the cleaning mechanism with respect to a rotational direction of the photoconductive cylinder, the wiping mechanism having an edge closest to the photoconductive cylinder, the wiping mechanism to wipe the cleaning fluid from the photoconductive cylinder while purposefully keeping a layer of the cleaning fluid on the photoconductive cylinder.

A method comprising:
- rotating a photoconductive drum;
- selectively transferring colorant from the photoconductive drum onto media to form a specified image on the media;
- at least substantially removing the colorant that remains on the photoconductive drum after selective transfer thereof onto the media by using a cleaning solution;
- and
- wiping the cleaning solution from the photoconductive drum after removing the colorant from the photoconductive drum while purposefully maintaining a layer of the cleaning solution on the photoconductive drum.
