ABSTRACT:
A non-deformable metallic pulley is coated with a urethane layer having a thickness of about 0.0005 inches. A drive belt, coupled to a recording head, is positioned over the urethane layer of the pulley, which in turn is driven by a stepping motor. The drive pulley is non-deformable, to eliminate backlash and yet has a very high coefficient of friction, about double that of steel, which is maintained consistent throughout the operation of the drive system, regardless of exposure to paper dust, dirt, oil and the like.
