1. General information
The Lexmark™ 3300 Series (4479-XXX) All-In-One features an electro-
mechanical color scanner, copier, and printer 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 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.
