Abstract: An end sealed metering apparatus includes a cylindrical metering roll mounted for rotation about a central longitudinal axis, a blade aligned with the longitudinal axis and contacting the metering roll, an elastomeric seal supported against an end of the metering roll, a rigid plate coupled with the elastomeric seal for holding the elastomeric seal stationary while the metering roll rotates, and a spring for urging the rigid plate and elastomeric seal against the end of the metering roll.

Abstract: An improved fusing apparatus including a baffle assembly having at least one member for imparting an arcuate-shaped profile in a sheet of recording substrate subsequent to the transport thereof through a fuser nip. The arcuate-shaped profile is imparted along a generally central axis of the recording substrate, substantially perpendicular to the path of movement thereof, providing lateral strength to the substrate for eliminating the formation of longitudinal waves therein.

Abstract: An apparatus in which at least a pair of developer rollers deposit toner particles on an electrostatic latent image recorded on a photoconductive member to render it visible. One of the rollers rotates at a first tangential velocity being spaced a first distance from the photoconductive member. The other roller rotates at a second tangential velocity being spaced a second distance from the photoconductive member. The second tangential velocity is greater than the first tangential velocity with the second distance being less than the first distance.

Abstract: An optical system in which successive color filtered light images pass through a screen positioned at discrete preselected angles. An un-filtered light image is transmitted through the screen with the screen being positioned at one of the preselected angles for the filtered light image.
