Harness the power of the standard multi-core processor and 1 GB of memory to simultaneously handle tasks like print, copy and scan, all while supporting your interaction with the 4.3-inch [10-cm] e-Task touch screen. A standard two-sided document feeder adds powerful batch scanning capabilities. A durable steel frame, available extra input trays and toner cartridges that can print up to 25,000 pages all minimize interruptions.
