4. Squeeze the tab at the back of the cartridge and lift it straight out. Dispose of
it carefully. Do not take the used cartridge apart or try to refill it.
Warning:
If ink gets on your hands, wash them thoroughly with soap and water. If ink gets
into your eyes, flush them immediately with water. If discomfort or vision problems
continue after a thorough flushing, see a doctor immediately.
5. Remove the new ink cartridge from the package.
Caution:
Be careful not to break the hooks on the side of the ink cartridge when you remove
it from the package.
Always install an ink cartridge immediately after removing the old cartridge. If
the cartridge is not installed promptly, the print head may dry out and be unable
to print.
Do not touch the green chip on the side of the cartridge. This can damage the
ink cartridge.
