What could cause an Epson L5190 E-02 error after installing a new ink cartridge?

If you get E-02 after installing a new cartridge, ensure the cartridge is correctly seated and locked into place. Sometimes, a new cartridge can introduce air into the ink system. Try running the print head cleaning utility immediately after installing the new cartridge. If the problem persists, the new cartridge itself might be defective, and you should contact the retailer or Epson support.
