Static build-up control in dispensing system

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;
• an electronic controller affixed to the chassis and adapted to control dispensation of the sheet material;
• and
• a conductive path extending from the roller toward 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.

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 spring 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 wire having a first end electrically coupled to the surface contact spring and a second end coupled to an element internal to the dispenser.
