Abstract
Cleaning a photoconductive surface (16) from particles and excess fluid with at least two wiper blades, wherein a first wiper blade (12) is to contact the photoconductive surface (16) and to wipe at least some of the particles and at least some of the excess fluid from the photoconductive surface (16) and wherein a second wiper blade (14) is to contact the photoconductive surface (16) and to wipe at least some of the particles and at least some of the excess fluid that have passed the first wiper blade, from the photoconductive surface (16).
Claims15
A cleaning system for cleaning a photoconductive surface from particles and excess fluid, the photoconductive surface moving relative to the cleaning system, the cleaning system comprising:
- at least two wiper blades comprising a first wiper blade and a second wiper blade;
- the first wiper blade to contact the photoconductive surface and to wipe at least some of the particles and at least some of the excess fluid from the photoconductive surface;
- and
- the second wiper blade to contact the photoconductive surface and to wipe at least some of the particles and at least some of the excess fluid that have passed the first wiper blade, from the photoconductive surface.
An apparatus comprising a member having a photoconductive surface and a cleaning system for cleaning the photoconductive surface from particles and excess fluid, the photoconductive surface moving relative to the cleaning system, the cleaning system comprising:
- at least two wiper blades comprising a first wiper blade and a second wiper blade;
- the first wiper blade to contact the photoconductive surface and to wipe at least some of the particles and at least some of the excess fluid from the photoconductive surface;
- and
- the second wiper blade to contact the photoconductive surface and to wipe at least some of the particles and at least some of the excess fluid that have passed the first wiper blade, from the photoconductive surface.
A method of cleaning a photoconductive surface from ink residues and imaging oil, comprising:
- applying imaging oil to a photo imaging plate, PIP, drum having a photoconductive surface;
- turning the PIP drum past a first wiper blade that contacts the photoconductive surface of the PIP drum and wipes at least some of the ink residues and at least some of the imaging oil from the photoconductive surface;
- and
- turning the PIP drum past a second wiper blade that contacts the photoconductive surface and wipes at least some of the ink residues and at least some of the imaging oil that have passed the first wiper blade from the photoconductive surface.
