1. General information

The Lexmark™ X6170 4408-K01/AK1 and X6150 4408-K02/AK2 machines feature an electro-mechanical color scanner, printer, copier, and fax that creates characters and graphics by composing programmed patterns of ink dots using a printhead and liquid ink. The printhead uses small heater plates and nozzles to control ink flow and the formation of characters on the print media. The printhead assembly and ink supply are combined into a single-unit, print cartridge available as a customer replaceable supply item. Du al printheads provide color and true black printing without changing printheads. The number and size of inkjets or nozzles, in the printhead, determines the overall quality and capability of the printer. The black cartridge has a total of 208 nozzles and installs on the le ft. The color cartridge has a total of 192 nozzles and installs on the right. The printer is capable of printing in two directions from either cartridge.
