Some months are busier than others, but the CS517de can handle them. It's recommended for printing up to 7,000 pages per month at speeds of up to 30 pages per minute. Each page features professional-quality colour with proven PANTONE colour accuracy. The CS517de also offers advanced security, Gigabit networking, a 10.9 cm colour touch screen, keypad, 2-sided printing, together with High Yield cartridges and mobile print capability. Colour matching tools and PANTONE calibration make it easy to get consistent, accurate colour output so you can save time and money by creating colour documents in-house. Thanks to a dual-core processor and 512MB of memory standard (expandable up to 2.5GB), even documents with graphics and images print quickly. The CS517de can deliver the first colour page in as little as 10 seconds. Extensive network security features and protocols protect your device, information and network from unauthorised access. Keep your sensitive documents safe by enabling the Confidential Print feature, which requires entering a customised, unique PIN on the device's keypad before the document can be printed. In addition, you can print from mobile devices using Lexmark's free Mobile Print app or an optional Wi-Fi adapter.
