Powered by the revolutionary Digital LED technology, the OKI ES8473dn makes high-volume print routines extremely fast and ink-efficient. Its main image engine has no moving parts, as the LED print head remains stationary and merely blinks the pattern of the content onto the page. This provides for a sturdy mechanism and ergonomic functioning. Since it has fewer moving parts, it is much more reliable than laser copiers and is lesser prone to breakdown. The LED technology also provides for precise representation of content on printed material.
