1. General Information

The Lexmark X83 machine is an electro-mechanical 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 single­unit, 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 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 two directions from
either cartridge.

Power Consumption

• <6 Watts - power off and power to the printer

• 8 Watts - Idle Mode (power on - not printing)

• 21 Watts - Printing (average)
