N7385-21 Two-Color Page Printer

In January 1987, NEC announced the world's first two-color high-speed page printer.This was the first high-speed page printer (2500line/min) in the world capable of simultaneously printing two colors. By using an amorphous silicon photoreceptor, it solved the problem of "mixed colors" which was an issue for two-color simultaneous printing. This enabled sharp printing.
