Lexmark 30E - Manual (Page 12)

Lexmark's warranty does not cover damage caused by non-Lexmark ink or ink cartridges.
Replacing ink cartridges
Make sure you have a new ink cartridge or cartridges before you begin. You must install new cartridges immediately
after removing the old ones or the ink remaining in the printhead nozzles may dry out.
1 Turn on your printer.
2 Open the printer.
Note: The printhead moves to the cartridge installation position.
3 Press the release tab, and then remove the used ink cartridge or cartridges.
4 Install each ink cartridge. Use two hands to install the black cartridge.
Note: Install the new ink cartridges immediately after removing the protective cap to avoid exposing the ink to
air.
5 Close the printer.
