Methods and a system for dispensing
In one example, the invention includes steps of: activating feeding and exiting motors of a dispensing device that cause corresponding rollers to rotate in forward direction, wherein the feeding motor is operatively connected to a displacement optical sensor, wherein the feeding and exiting rollers move a dispensing object; wherein an exit sensor generates a first signal, indicating that a leading edge of the dispensing object has activated the exit sensor, generating, by the stationary displacement optical sensor, a second signal, when, by passing at least one light beam over a surface of the portion of the dispensing object, the stationary displacement optical sensor determines that the portion of the dispensing object has traveled a pre-determined distance along the dispensing passage.
