Abstract
A pulley tensioner for applying torque or tension to a pulley includes a spring system configured to encircle the periphery of the pulley. The spring system is anchored to the pulley housing or some other fixed location. The spring system is made up of one or more coil springs which are wrapped around the periphery of the pulley. Where multiple springs are used, preferably each spring has a different spring constant and length. This allows the operator to select the desired tension depending upon the operating parameters of the printer. The applied tension may be further modified/tuned by using an additional spring member to anchor the spring system to the pulley housing or some other fixed location.
