Rhemson 0 Report post Posted September 6, 2019 This is my case. I just receive my new epson p600 with ciss. I downloaded the printer driver and i was accidentaly update the firmware version. When i power on the button, it says ink not recognized. So I bought firmware key. The firmware was succesfully installed to my printer. When i press the power on, the error message disappear. And i was happy. This is my problem now, when i started to do printing job, the error ink cartridge not recognized came back. This happens only when the printer started to perform the printing. Pls help me this fix. Thanks Share this post Link to post Share on other sites
