Paper Transport Method for (roller and fixed point) (low paper detection)

A paper roll of diminished size is transported through the transition from a running size to a paper low trigger size. This invention teaches what has to be done if the transport is between a rolling point and a fixed point. The rolling and fixed point balances the cost of adding a roller with the speed at which the paper can be transported without going to two rollers. Therefore disclosed is a method whereby a low roll of paper can fall through to a sensing apparatus and a larger roll of paper can work within the same bucket. The roller and fixed point support the large diameter as well as allowing for smooth transport of the smaller diameter as it transitions to the low paper roll diameter and falls through to the sensor beneath. This is accomplished with one roller and one fixed point within the bucket in a set manner to facilitate the transport of paper with lower friction then a design with no rollers and is less cost then a design with two rollers. Traditional design of the receipt paper bucket calls for a hard edge support (static support) on the front of the paper roll and a roller support on the rear of the paper roll. The low paper roll becomes stuck between the roller and static support in the printer bucket when roll diameter approaches low paper. Taught is th...
