1. General information
The Lexmark™ 7300 Series All-In-One (4418-X6X) is a letter-quality print,
fax, copy, and scan machine. It is a standalone color/mono copier and fax.
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. 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 640 nozzles and installs on the
left. The color cartridge has a total of 480 nozzles and installs on the right.
The photo cartridge has a total of 480 nozzles and installs on the left. The
All-In-One is capable of printing in two directions from either cartridge.
