Memjet technology is comprised of four tightly integrated components: page-width printheads, driver chips, ink and software. Printheads are comprised of individual microchip segments, joined together into page-width printing systems. Each chip measures just 20mm across and contains 6,400 nozzles. The printheads incorporate five color channels that can be flexibly configured to meet the needs of diverse markets. The driver chip is an integrated printing system that calculates 900 million drops per second and drives 70,400 nozzles in a standard A4/letter printer, delivering color page-width printing at 60 pages per minute. The Memjet software is highly portable and modular, allowing software developers to drive Memjet printers at rated speed and quality avoiding the details of printhead, nozzles or hardware. Printheads and driver chips can scale from 20mm to large format sizes, enabling printing in virtually any width. Customized water-based inks ensure great print quality whether printing photos, office documents or industrial labels.
