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.

1-32. (canceled)
A moistening device for regulation of sliding properties of a printing substrate in an electrophotographic printer or copier that generates and fixes toner images of images to be printed onto the printing substrate, comprising:
- a rotor nebulizer or a spray nozzle arranged adjacent to the printing substrate that applies on the printing substrate a moistening agent made from a moistening fluid and a lubricant dissolved therein.
An electrophotographic printer or copier device, comprising:
- a printing station;
- and
- at least one post-processing device after the printing station at an output of the printer or copier device which processes the printing substrate, the at least one post-processing device comprising a rotor nebulizer or a spray nozzle arranged adjacent to the printing substrate that applies on the printing substrate a moistening agent made from a moistening fluid and a lubricant dissolved therein.
A method for moistening and lubricating a printing substrate in an electrophotographic printer or copier device wherein a moistening agent made from a moistening fluid and a lubricant is applied on the printing substrate with a moistening device comprising a rotor nebulizer or a spray nozzle arranged adjacent to the printing substrate.
An electrophotographic printer or copier device, comprising:
- a printing device that generates toner images of images to be printed onto the printing substrate;
- a fixing device which fixes the toner images on the printing substrate, said fixing device deteriorating moisture content and sliding properties of the printing substrate;
- and
- a moistening device comprising a rotor nebulizer or a spray nozzle arranged adjacent to the printing substrate that applies on the printing substrate a moistening agent comprising a moistening fluid and a lubricant to improve moisture content and slidability of the printing substrate.
A method for regulation of sliding properties of a printing substrate in an electrographic printer or copier that generates and fixes toner images onto the printing substrate, and wherein the fixing deteriorates moisture content and sliding properties of the printing substrate, comprising the steps of:
- providing a moistening device comprising a rotor nebulizer or a spray nozzle arranged adjacent to the printing substrate, the moistening device being located after a fixing station;
- and
- with the moistening device applying on the printing substrate a moistening agent comprising a moistening fluid and a lubricant dissolved therein.
