Sensing retracting leading edge in automatic towel dispenser

A method of dispensing towels from toweling with a dispenser, comprising:

• using a motor assembly configured to cause a leading edge of the toweling to be extended from a housing of the dispenser and to cause the toweling to be subsequently retracted back into the housing, extending the toweling exterior of the housing for grasping by a user, such extension causing a line of perforations of the toweling to be disposed downstream of a sensor of the dispenser;
• and
• following tearing, by a user, of the toweling at the line of perforations that is disposed downstream of the sensor:
• retracting the toweling into the housing the motor assembly;
• sensing a leading edge of the toweling, using the sensor, while retracting the toweling;
• and
• ceasing retracting of the toweling into the housing the motor assembly as a function of sensing the leading edge of the toweling using the sensor.
