1. General information
The Lexmark™ C77x, C78x (5061-xxx) is a network-capable color printer that uses electrophotographic
technology to deliver high-quality images, presentation graphics, line art, and text. It prints both four-color and
monochrome print jobs.
The flexible design supports a variety of printing needs. For example, if you need the printer to match the color
process used in a particular application, you can select RGB or CMYK color corrections. You can also adjust the
printed colors to more closely represent the colors on your computer display.
A variety of connectivity options enable the printer to be used in all types of system environments. You can
attach one internal adapter to support network configurations requiring Ethernet, Token-Ring, LocalTalk, serial,
infrared, or additional parallel ports.
The printer has flexible paper handling. It supports a wide variety of paper sizes, and has a standard
multipurpose feeder that makes it easy to print on envelopes, transparencies, labels, card stock, and non-
standard size paper. You can add optional inputs to the base printer, which can increase the printer paper
capacity to 3100 sheets.
