Static build-up control in dispensing system

1. A method of grounding a dispenser comprising:

connecting a low impedance path to elements internal to the dispenser;

connecting the low impedance path to a surface contact adapted to contact an external mounting surface when the dispenser is affixed to the external mounting surface; and

discharging static electrical charge accumulated on the elements to the external mounting surface through the low impedance path and the surface contact.

2. The method as in claim 1 , wherein the dispenser includes a nib roller and the method further comprises connecting the low impedance path to the nib roller.

3. The method as in claim 2 further comprising connecting a shaft of the nib roller to the low impedance path using a spring contact.

4. A paper dispenser comprising:

a support adapted to hold a roll of a paper;

a motor driven feed mechanism adapted to receive and dispense paper from the roll;

a surface contact adapted to directly contact a mounting surface external to the dispenser when the dispenser is affixed to the mounting surface; and

at least one low impedance conductor having a first end electrically coupled to surface contact and a second end coupled to an element internal to the dispenser.

5. The dispenser of claim 4 , wherein the feed mechanism includes a nib roller and the second end of the at least one low impedance conductor is coupled to the nib roller.

6. The dispenser of claim 5 , wherein the dispenser further comprises a spring-contact coupling the second end of the at least one low impedance conductor to the nib roller.

7. The dispenser of claim 6 , wherein the nib roller includes a shaft and the spring contact couples the second end of the at least one low impedance conductor to the shaft.

8. The dispenser of claim 4 , wherein the mounting surface comprises at least a portion of a wall.

9. The dispenser of claim 8 , wherein the wall is formed from a high impedance material.

10. The dispenser of claim 4 , wherein the dispenser comprises a chassis, the chassis being affixed to the mounting surface.

11. The dispenser of claim 10 , wherein the chassis comprises a plastic material.

12. A dispenser for dispensing flexible sheet material comprising:

a chassis including a mounting member adapted to affix the chassis to a support surface;

a feed mechanism affixed to the chassis, the feed mechanism including at least one roller and being adapted to advance sheet material from a roll of sheet material across the roller; and

a conductive path comprising a conductor, the conductive path being disposed between the roller and the mounting member, wherein the conductive path is adapted to contact the support surface when the chassis is affixed thereto and to discharge static electricity accumulated on the at least one roller to the support surface.

13. The dispenser of claim 12 , wherein the roller includes a roller shaft and the conductive path includes a conductive contact adapted to contact the roller shaft.

14. The dispenser of claim 13 , wherein the conductive contact is spring biased against the roller shaft.

15. The dispenser of claim 13 , wherein the conductive contact comprises a compression spring.

16. The dispenser of claim 12 , wherein the mounting surface comprises at least a portion of a wall.

17. The dispenser of claim 16 , wherein the wall is formed from a high impedance material.

18. The dispenser of claim 12 , wherein the dispenser comprises a chassis, the chassis being affixed to the mounting surface.

19. The dispenser of claim 18 , wherein the chassis comprises a plastic material.

20. The dispenser of claim 12 , wherein the support surface comprises a at least a portion of a wall.

21. The dispenser of claim 20 , wherein the wall is formed from a high impedance material.

22. The dispenser of claim 12 , wherein the chassis comprises a plastic material.
