Abstract

Disclosed is a high volume color loop sub system for integration with a black only marking engine. The subsystem provides an add on color loop thereby enabling, for example, a mid volume black only machine to provide full color image output at the same print rate. The color loop subsystem can use a lower resolution exposure system capability while reserving high resolution for black development. The color loop is only used when color is desired preserving reliability, cost and maintainability.

HIGH VOLUME COLOR LOOP (Cont'd)

Disclosed is a high volume color loop sub system for integration with a black only marking engine. The subsystem provides an add on color loop thereby enabling, for example, a mid volume black only machine to provide full color image output at the same print rate. The color loop subsystem can use a lower resolution exposure system capability while reserving high resolution for black development. The color loop is only used when color is desired preserving reliability, cost and maintainability.

As shown in the figure, the color loop subsystem 1 is joined or interfaced with a black only system 2 by color transfer intermediate roll 3. The color loop provides a plurality of color marking engines, for example, Cy (cyan), Mg (magenta), Y (yellow) and the like, and integrates color images with black only images from development system 5.
