Abstract:
A printer assembly includes an idler pulley, a printhead carrier belt, an idler-pulley spring, and a ratchet stop. The printhead carrier belt is operatively connected to the idler pulley and extends in an inboard direction from the idler pulley. The idler-pulley spring biases the idler pulley in an outboard direction to maintain belt tension as the belt lengthens during wear. The ratchet stop is located inboard of the idler pulley and operatively engages the idler pulley against movement of the idler pulley in the inboard direction, wherein such inboard movement would cause printing errors.
