Abstract
Herein is described a liquid electrophotographic a printing apparatus comprising: a photoconductor; a liquid electrophotographic ink developer unit for applying liquid electrophotographic ink to the photoconductor; a cleaner roller contactable with the photoconductor, the cleaner roller comprising an open-celled foam material having thereon a coating comprising abrasive particles and a binder. Also described herein is a cleaner roller for cleaning a liquid electrophotographic printing apparatus’ photoconductor and a method of operating a liquid electrophotographic printing apparatus using a cleaner roller described herein.
Claims15
A liquid electrophotographic printing apparatus comprising:
- a photoconductor;
- a liquid electrophotographic ink developer unit for applying liquid electrophotographic ink to the photoconductor;
- a cleaner roller contactable with the photoconductor, the cleaner roller comprising an open-celled foam material having thereon a coating comprising abrasive particles and a binder.
A cleaner roller for cleaning a liquid electrophotographic printing apparatus’ photoconductor, the cleaner roller comprising an open-celled foam material having thereon a coating comprising abrasive particles and a binder, wherein the binder is formable from an isocyanate and a polyol.
A method of operating a liquid electrophotographic printing apparatus, the method comprising:
- applying a liquid electrophotographic ink to a photoconductor having a latent electrostatic image thereon to form a developed image comprising the liquid electrophotographic ink;
- transferring the developed image, in reversed form, to an intermediate transfer member or a print medium in contact with the photoconductor;
- cleaning excess ink or components thereof from the photoconductor by contacting the photoconductor with a cleaner roller, the cleaner roller comprising an open-celled foam material having thereon a coating comprising abrasive particles and a binder.
