Abstract
A dual roll dispenser is disclosed. The device comprises a housing unit having a first paper towel roll and a second paper towel roll mounted therein. Paper automatically dispenses paper from one of the rolls while the second roll remains idle. When a sensor detect that the roll being dispensed is exhausted, the device automatically engages the second paper towel roll and begins dispensing from this second roll. Displays, both local and remote, are activated to communicate a paper absent condition. The device can be used in standalone configuration or in conjunction with an air blower wherein activation of the device activates the air blower for a preset amount of time and thereafter dispenses a single paper towel sheet.
