The OKI ES4131 is a black & white printer that supports the highest levels of office productivity ? without straining your budget. Built for speed and maximum efficiency, it produces the first printed page in less than 4.5 seconds and the rest at an impressive 38 pages per minute. The compact design of the ES4131 means it can be placed on any desktop within your office, for easy arms-reach access to all your printed documents. Other essential features include automatic two-sided printing as standard, a ?Power Save? mode that reduces energy consumption to just 8W, and because the toner cartridge and drum are all separate, you reduce waste by only ever having to replace what needs replacing. Maximum reliability means maximum return on investment. And that?s what the robust, built-to-last designed ES4131 delivers. It uses ultra-reliable digital LED technology (pioneered by OKI and proven over more than 20 years) with fewer moving parts for exceptional durability for even the most demanding workloads.
