Procedure for fixing of toner on a print material and fixing device
View Patent ↗An apparatus and procedure for the separation of a fixing roller from the print material, wherein, contamination of the print machine and the print material by release oil is avoided. A toner layer is applied to the printing material and, at minimum, a release material layer is directly applied to the printing material, upstream of the fixing roller, which makes possible reliable separation of the fixing roller from the print material.
1. Procedure for fixing toner on a print material ( 9 ) with the help of a fixing roller ( 1 ), in which at least a toner layer ( 10 ) is applied to print material ( 9 ), wherein at least one layer ( 12 ) of release material is applied directly to print material ( 9 ), upstream of fixing operations which makes possible reliable separation of fixing roller ( 1 ) from print material ( 9 ) with toner layer ( 10 ).
2. Procedure according to claim 1 , wherein the amount of release material of layer ( 12 ) is regulated depending on the desired gloss on print material ( 9 ).
3. Procedure according to claim 1 , wherein the amount of release material of layer ( 12 ) is regulated depending on the type of print material.
4. Procedure according to claim 1 , wherein the release material of layer ( 12 ) includes toner.
5. Fixing device ( 3 ) for fixing of toner on a print material ( 9 ) with the aid of a fixing roller ( 1 ), wherein a device ( 25 ) for control of application of layer ( 12 ) of release material directly onto print material ( 9 ), upstream of the fixing roller ( 1 ), which makes possible reliable separation of fixing roller ( 1 ) from print material ( 9 ) with toner layer ( 10 ).
6. Fixing device ( 3 ) according to claim 5 , wherein release material of layer 12 includes small capsules of release oil.
