Introduction
Inkjet Printers
An inkjet printer is an electro-mechanical printer that
forms characters on print media (paper, transparency,
etc.) 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.
Lexmark combines the printhead assembly and ink
supply into one unit called a print cartridge.
The monochrome print cartridge contains black ink and
more nozzles than a color print cartridge. The color
print cartridge contain three colors of ink: cyan,
magenta and yellow.
Lexmark inkjet printers provide high quality text and
graphic printing. Lexmark printers can print on
envelopes, single sheet paper labels, 3 x 5 index cards,
and transparencies.
