1. General information
The Lexmark 4300 Series (4421-XXX) Photo All-In-One features an
electro-mechanical color scanner, printer, and copier 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. 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 print 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 print cartridge.
