    2Ink cartridges cannot be replaced
    There are two possible causes.
    Because there is only a small amount of ink remaining, 
    you cannot replace it with a different type of black ink cartridge.
    (However, you may be able to replace it with the same type of black ink 
    cartridge.)
    Replace it with a new ink cartridge. We recommend using genuine Epson 
    ink cartridges.
    Or, the currently installed black ink differs to the type of cartridge used 
    when printing started.
    Replace the currently installed black ink cartridge with the same type of 
    previously installed black ink cartridge.
    Once it is replaced, printing will resume automatically. If you do not want to 
    replace the ink cartridge, click the Cancel button.Refer to Table 3-10 Troubleshooting of Ink Color Error
