    • A low paper sensor mechanism including first and second support rollers rotatable about a first and second rotational axis to support a paper supply roll, the first and second support rollers and rotational axes configured to translate in a path between a first position and a second position, first and second biasing members biasing the first and second support rollers toward the second position and a detection device, including a light emitting element and a light detecting element, disposed adjacent to the first and second support rollers, wherein the first and second support rollers move from the first position to the second position when a diameter of the paper supply roll is less than or equal to the predetermined distance between the first and second support rollers and the paper supply roll disrupts a line of sight between the light emitting element and the light detecting element.
