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.
