With the Phaser® 340 color printer, Tektronix commercialized a new high-speed color-printing process. The method and the engine architecture result from the combination of solid ink-jet printing with drum-based offset printing. The benefits of this printing technology are plain-paper printing in full color at multiple pageper- minute speeds and exceptional transparency quality. The basic elements of the engine include proprietary phase-change inks, a page-wide printhead, offset drum, and transfer roller. A review of the engine architecture and its relationship to printer performance is described. Additionally, the characteristics of the core technology components are summarized.
