1. General Information
The Lexmark X125 All-In-One (4412-00X) 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.
