A first page as fast as four seconds sets the stage for printing and copying at up to 70 [66] ppm, backed by the powerful combination of 1.2-GHz quad-core processor and up to 6 GB of memory. Single-pass two-sided scanning at up to 150 [144] spm completes the speed equation, bolstered by bigger-than-ever 200-page document feeder capacity. Steel frames and a robust paper feeding system that reliably handles diverse media types and sizes support heavy-duty use and a long life in even the harshest environments. Plus, innovations in part replacement and accessibility help you resolve problems quickly. With access to input capacity of up to 3300 sheets, replacement toner cartridges that go as high as 55,000 pages, 200-sheet automatic document feeder, long-life imaging unit and fuser that may never need replacement, you'll spend more time printing and less time doing maintenance.
