Abstract
A printing drum for a liquid electrophotographic printing system which comprises a photosensitive surface and a heating device mounted to the printing drum. The heating device heats the photosensitive surface of the printing drum to a predetermined temperature.
Claims15
A printing drum for a liquid electrophotographic printing system, the printing drum comprising:
- a photosensitive surface,
- a plurality of heating pads mounted to the printing drum, and
- a controller electrically coupled with the plurality of heating pads,
- wherein the controller is to control the heating pads independently such that the photosensitive surface of the printing drum is heated to a temperature having a predetermined temperature distribution.
1 more element
A liquid electrophotographic printing system, comprising
- an intermediate member,
- at least one printing drum, comprising:
- a photosensitive surface,
- a heating device, and
- a controller electrically coupled with the heating device;
- wherein the at least one printing drum is selectively engaged with the intermediate member during a press-priming process and wherein the controller is to control the heating device such that the photosensitive surface is heated to a press priming temperature higher than 80° C. to heat the intermediate member during the press-priming process.
3 more elements
A method to heat a photosensitive surface of a printing drum in a liquid electrophotographic printing system, comprising:
- - heating the photosensitive surface with a heating device mounted to the printing drum to a temperature higher than 80° C. during at least one of a print quality enhancing process to enhance the print quality of the photosensitive surface and a press priming process.
