1. General Information

The Lexmark™ X63 All-In-One is a letter quality print, fax, copy and

scan machine. 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 cartridges are available as a customer replaceable supply

item. Dual 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 right. The color cartridge has a total of 192 nozzles and installs

on the left. The printer is capable of printing in both directions from

either cartridge.
