As the Dancer Roller moves upward thus shortening the optical path between Sensor

and Target bracket, the servo motor powering Roller #3 begins to move Roller #3 to

pull printer paper off the continuous media roll and into the Infeed. The motor

speeds up progressively as the Dancer moves up until Infeed Roller #3 exactly

matches the speed of the print engine Infeed Rollers.
