<p>Embodiments of a compact electrophotographic color developer module are shown and described, each embodiment including generally vertically-oriented, self-contained developers, stacked or radially fanned-out above the photoconductor drum. The developers are preferably either wedge-shaped or rectangular, and preferably have cylindrical sleeves less than about 2 inches apart. The compact developer module and cooperating image transfer system have a small form factor and footprint and may be used in a wide variety of electrophotographic platforms with minimal changes. A cam system may be included to allow either contact, non-contact, or close-jump-gap development, with a simple code or ROM change. The photoconductor drum is sized to carry less than a complete image, because the image is transferred to an intermediate transfer member before transfer to paper. With extension of the developer canisters and/or of the intermediate transfer member, the system may be easily adapted for increased toner capacity, life and media size, respectively, with minimum or no effect on form factor and footprint. With extension of the width of photoconductor drum and transfer belt components, the system may be easily adapted for portrait or landscape media orientations.</p> |
