The OKI Data B420dn Digital Monochrome printer delivers up to 30 ppm, with the first page printing in as little as 5.5 seconds. It produces output in black & white that's clear and crisp, at up to 2400 x 600 dpi resolution, using a two-piece consumables system for long-lasting performance and a low cost of operation. The B420dn comes with duplex (2-sided) printing standard, leading to fewer user interventions and savings on media costs. With a 50-sheet multi-purpose tray, it has a 580-sheet standard capacity which can be expanded with an optional 530-sheet 2nd paper tray. In terms of durability and reliability, the B420dn is tough-with a monthly duty cycle as high as 70,000 pages.
