You may continue printing, or click the How to button to change the ink cartridge now.Refer to Table 3-9 Troubleshooting of Ink Low (P.48) Ink Color error* 1 -- Flashes at high speed* 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 (Stylus Photo R2880 only) (P.48) Table 3-1.
