Abstract

An electrophotographic printing machine is supported by a caster. The caster is adjustable to allow the printing to be leveled and aligned on uneven floors. The caster includes a wheel simply supported rotatably between a pair of crank arms. The arms are mounted on a worm gear having shaft passing through its pivot. The worm gear meshes with a vertically oriented worm having the uppermost end thereof located in a mounting on the printing machine base. As the worm is rotated, the worm gear rotates to raise and lower the printing machine by rotating the caster crank arms.
