Abstract
In an electrophotographic printer or copier, toner images of images to be printed onto a printing substrate are generated and fixed, causing sliding characteristics to be worsened. In order to remedy this problem, a moistening device is provided that applies on the printing substrate a moistening agent made from a moistening fluid and a lubricant dissolved therein. Two problems are thus solved: the printing substrate is moistened and simultaneously lubricated.
Claims25
A moistening device for regulation of sliding properties of a print substrate in an electrophotographic printer or copier that generates and fixes toner images of images to be printed onto the printing substrate, comprising:
- a moistening agent for application on the printing substrate and made from a moistening fluid and a lubricant soluble therein for regulation of sliding properties of the printed substrate;
- a roller arrangement comprising at least one application roller arranged on a side of the printing substrate;
- an application element arranged adjacent to the application roller, the application element comprising a feedthrough and a distributor channel with a distributor gap in a direction of the application roller for transfer of the moistening agent onto a surface of the application roller;
- and
- a counter-element on a side of the printing substrate situated opposite the application roller.
An electrophotographic printer or copier device, comprising:
- a machine for post-processing of a printing substrate;
- and
- said machine comprising a moistening device arranged at an output of the printer or copier device, said moistening device comprising
- a moistening agent for application on the printing substrate and made from a moistening fluid and a lubricant soluble therein for regulation of sliding properties of the printing substrate, said moistening device comprising a roller arrangement,
- at least one application roller arranged on a side of the printing substrate,
- an application element arranged adjacent to the application roller, the application element comprising a feedthrough and a distribution channel with a distributor gap in a direction of the application roller for transfer of the moistening agent onto a surface of the application roller, and
- a counter-element on a side of the printing substrate situated opposite the application roller.
An electrophotographic printer or copier device, comprising:
- a station for fixing of toner images onto a printing substrate;
- and
- a moistening device arranged after said station for fixing of the toner images, said moistening device comprising
- a moistening agent for application on the printing substrate and made from a moistening fluid and a lubricant soluble therein for regulation of sliding properties of the printing substrate,
- a roller arrangement comprising at least one application roller arranged on a side of the printing substrate,
- an application element arranged adjacent to the application roller, the application element comprising a feedthrough and a distributor channel with a distributor gap in a direction of the application roller for transfer of the moistening agent onto a surface of the application roller, and
- a counter-element on a side of the printing substrate situated opposite the application roller.
