In a gear train having a first gear, a second gear in mesh with the first gear, and a third gear in mesh with the second gear, an anti-backlash mechanism having a first anti-backlash gear positioned in operative relationship with the first gear and the second gear, a second anti-backlash gear positioned in operative relationship with the second gear and the third gear, whereby the first anti-backlash gear controls backlash between the first gear and the second gear, and the second anti-backlash gear controls backlash between the second gear and the third gear. Additionally, in a gear train having a first gear, a second gear in mesh with the first gear, and a third gear in mesh with the second gear, a method for reducing backlash comprising providing a first anti-backlash gear positioned in operative relationship with the first gear and the second gear, and providing a second anti-backlash gear positioned in operative relationship with the second gear and the third gear, whereby the first anti-backlash gear controls backlash between the first gear and the second gear, and the second anti-backlash gear controls backlash between the second gear and the third gear.
