Printing method for reducing printer artifacts
View Patent ↗A printing method comprising a printhead and rollers for printing. A page of a print job is printed which causes depressions in the non-printed side of the print medium. The print medium is heated to reduce the depressions before printing the non-printed side.
1. A method of printing comprising:
receiving a duplex printing medium inside a printer, including using a textured roller pressed against a first side of the duplex printing medium for drawing the printing medium into the printer;
printing on a second side of the duplex printing medium including using a thermal print head;
smoothing the first side of the duplex printing medium, wherein a size of indentations in the first side of the duplex printing medium caused by the textured roller is reduced; and
printing on the first side of the duplex printing medium after the step of smoothing.
2. Method of claim 1 wherein the step of smoothing comprises heating the first side of the duplex printing medium after the step of printing on the second side of the duplex printing medium.
3. Method of claim 2 wherein the step of heating comprises compressing the duplex printing medium against a heated surface.
4. Method of claim 3 wherein the step of compressing comprises using a heated roller.
5. Method of claim 4 wherein the step of using a heated roller comprises using a plurality of rollers wherein at least one of the plurality of rollers is heated.
6. Method of claim 3 further comprising heating the heated surface by passing an electric current therethrough.
7. Method of claim 6 further comprising passing the electric current through the heated surface while the duplex printing medium is being compressed against the heated surface.
8. A method of handling a printing medium comprising:
pulling the printing medium through a nip formed between a pinch roller and a textured capstan roller, wherein the capstan roller comprises a capability of one side of the printing medium to receive donor dye applied by a thermal print head to one side of the printing medium by forming a plurality of indentations thereon; and
smoothing the one side of the printing medium after the step of pulling the printing medium.
9. Method of claim 8 wherein the step of smoothing comprises heating the one side of the printing medium.
10. Method of claim 9 wherein the step of heating comprises pulling the printing medium through a nip formed by a pinch roller and a heated roller.
11. Method of claim 10 wherein heated roller is heated by passing an electric current therethrough.
12. Method of claim 11 further comprising passing the electric current through the heated roller during the step of pulling the printing medium through the nip formed by the pinch roller and the heated roller.
