Abstract

An apparatus for ink contaminant drying includes a marker platen having a topside and a bottom side, and a plurality of heating elements located beneath the topside of the marker platen. The plurality of heating elements provides heating with respect to a surface of the marker platen, which prevents ink contaminants on the surface from remaining in a viscous fluidic state over a period of time.

First claim

What is claimed is:

1. An apparatus for ink contaminant drying, comprising:
a marker transport belt and a marker platen, wherein the marker platen comprises a topside and a bottom side, the marker platen including platen guides and a plurality of vacuum channels formed from the platen guides, the marker transport belt configured with vacuum holes spaced periodically and aligned with the plurality of vacuum channels; and
a plurality of heating elements located beneath the topside of the marker platen in the platen guides of the marker platen and in proximity to areas with a high probability of ink contamination, which results in an efficient transfer of energy for drying out ink contaminants, wherein the plurality of heating elements provides heating with respect to a surface of the marker platen, which assist in preventing ink contaminants on the surface from remaining in a viscous fluidic state over a period of time, and wherein the areas with the high probability of ink contamination include a contact area between the marker transport belt and the marker platen, the contact area comprising a region most likely to suffer from ink contamination, wherein each heating element among the plurality of heating elements comprises a cartridge heating element.

2. The apparatus of claim 1 wherein the platen guides of the marker platen comprise a plurality of topside platen guides, wherein each heating element among the plurality of heating elements is respectively disposed in a hollowed out region within each topside marker platen surface guide among the plurality of platen guides.

3. The apparatus of claim 2 wherein the marker platen is configured from stainless steel, wherein the stainless steel comprises a conductor of heat that transfers the heat to the ink contaminants as a part of the heating.

4. The apparatus of claim 2 wherein each vacuum channel among the plurality of vacuum channels includes a vacuum port.

5. The apparatus of claim 2 wherein the marker transport belt is located above the platen guides.

6. The apparatus of claim 2 further comprising a printing system in which the marker platen and the plurality of heating elements are located and operate.

7. The apparatus of claim 6 wherein the marker transport belt is located above the platen guides in the printing system.

8. The apparatus of claim 1 wherein the marker platen comprises a plurality of landing areas upon which the marker transport belt rides.

9. A printing system that provides ink contaminant drying, comprising:
a marker transport belt and a marker platen, wherein the marker platen comprises a topside and a bottom side, the marker platen including a plurality of platen guides and a plurality of vacuum channels formed from the plurality of platen guides, the marker transport belt configured with vacuum holes spaced periodically and aligned respectively with the plurality of vacuum channels; and
a plurality of heating elements located beneath the topside of the marker platen in the plurality of platen guides of the marker platen and in proximity to areas with a high probability of ink contamination, which results in an efficient transfer of energy for drying out ink contaminants, wherein the plurality of heating elements provides heating with respect to a surface of the marker platen, which assist in preventing ink contaminants on the surface from remaining in a viscous fluidic state over a period of time, and wherein the areas with the high probability of ink contamination include a contact area between the marker transport belt and the marker platen, the contact area comprising a region most likely to suffer from ink contamination, wherein each heating element among the plurality of heating elements comprises a cartridge heating element.

10. The printing system of claim 9 wherein each heating element among the plurality of heating elements is respectively disposed in within a hollowed out region within a topside marker platen surface guide of the plurality of platen guides.

11. The printing system of claim 9 wherein the marker platen comprises stainless steel that comprises a conductor of heat that transfers the heat to the ink contaminants as a part of the heating.

12. The printing system of claim 9 wherein each vacuum channel among the plurality of vacuum channels includes a vacuum port.

13. The printing system of claim 12 wherein the marker transport belt is located above the plurality of platen guides.

14. The printing system of claim 13 wherein the marker platen comprises a plurality of landing areas upon which the transport belt rides.

15. A method for ink contaminant drying, comprising:
associating a marker transport belt with a marker platen having platen guides, a surface and a topside and a bottom side;
configuring the marker platen with a plurality of vacuum channels formed from the platen guides, the marker transport belt configured with vacuum holes spaced periodically and aligned with the plurality of vacuum channels;
locating a plurality of heating elements in the platen guides of the marker platen, wherein each heating element among the plurality of heating elements comprises a cartridge heating element; and
facilitating heating by the plurality of heating elements with respect to the surface of the marker platen having the topside and the bottom side, the plurality of heating elements further located beneath the topside of the marker platen and in proximity to areas with a high probability of ink contamination, the heating resulting in an efficient transfer of energy for drying out ink contaminants, wherein the plurality of heating elements provides the heating with respect to the surface of the marker platen, which assists in preventing the ink contaminants on the surface from remaining in a viscous fluidic state over a period of time, and wherein the areas with the high probability of the ink contamination include a contact area between the marker transport belt and the marker platen, the contact area comprising a region most likely to suffer from the ink contamination.

16. The method of claim 15 wherein the platen guides include a plurality of topside platen guides, wherein each heating element among the plurality of heating elements is respectively disposed in a hollowed out region within each topside marker platen surface guide among the plurality of platen guides.

17. The method of claim 16 further comprising:
configuring the marker platen further with stainless steel comprising a conductor of heat that transfers the heat to the ink contaminants as a part of the heating; and
forming a plurality of vacuum channels respectively from the plurality of platen guides; and
configuring each vacuum channel among the plurality of vacuum channels to include a vacuum port.

18. The method of claim 16 further comprising locating the marker transport belt above the platen guides.

19. The method of claim 18 wherein the marker platen comprises a plurality of landing areas upon which the marker transport belt rides.

20. The method of 18 further comprising operating the plurality of heating elements during a system idle time in which a plurality of print heads are capped and printing does not take place.
