Kyocera ECOSYS P2135dn in More Detail the Kyocera P2135nd from the ECOSYS range, is an ideal companion for those requiring continuous reliable performance from a simple black and white printer. Uninterrupted Performance At a top print speed of 35ppm, the 2135dn won't slow down your important workflow. The 1GB memory and powerful 500MHz processor is an upgrade from its sister model (the P2035 series) and ensure that even the most demanding, large print jobs are produced at the same speed instead of requiring more processing time. Money Saving ECO Features Double-sided printing is also included from the outset, providing your documents with that professional crisp feel whilst potentially cutting your media use by up to 50%. The cartridge free system consists of long life components ensuring that downtime and maintenance tasks are kept to a minimum and the toner is the only consumable requiring replacement at regular intervals. All of these features can be shared across your office via the included network interface giving your team the same consistent performance no matter what or when they want to print.
