Toshiba America Business Solutions showed off its e-STUDIO 520/600/720/850 multifunction series boasting speeds of 52, 60, 72 to 85 ppm. The printers use e-BRIDGE single-board architecture, providing a single circuit board to control copying, printing, scanning and other functionality. Boasting 2,400x600-dpi resolutions, the e-STUDIO 520, 600 and 720 all will feature a new high-speed, single-beam laser-imaging unit, while the e-STUDIO 850 will use a dual laser-beam design. All four models will include Toshiba's new Serial Filter, which renders higher-fidelity grayscales for more deliberate shades of gray, as well as an eight-bit scanner. Additionally, a new dual speed paper handling system slows down the paper while it passes through the process unit, making up the speed elsewhere to maintain performance.
