Abstract: Arcuate Reciprocating Optics Drive Mechanism A copier having a stationary document glass and a scanning illumination/optics mechanism. The illumination/optics mechanism reciprocates through a linear scan motion and a reverse-direction reset motion during a copy process cycle. A moving photoconductor is connected to move the scanning mechanism in a scanning direction for a first part of the photoconductor movement, and to move the mechanism in the opposite reset direction during a second part of the photoconductor movement. Rotary-to-reciprocating harmonic motion mechanism couples the photoconductor's motion to the scanning mechanism to move the mechanism through the scan and reset motion.

Abstract: HOLLOW FUSER ROLL WITH VARIABLE TAPER An electrophotographic copier machine with a roll fuser where one of the mating rolls is comprised of a thin outer shell which takes a variable taper so that a concave shape is produced under high humidity conditions and a relatively straight roller is produced under low humidity conditions. Means for changing the support at the roll ends is provided to produce the variable taper. End plugs can be moved axially inward at high humidity to provide support for the end portions of the normally concave roll and can be moved axially outwardly under low humidity such that no support is provided until the roll ends are flattened under the pressure of a mating roll.
