Dunc 0 Report post Posted October 17, 2019 Newest Epson firmware update (Ver CL27J9) caused printer to not recognize the previously acceptable cartridges. I got it into "Update" mode, connected the USB cable, but my Dell laptop/Win10 does not connect to the printer so no Firmware Update can be done. I disables the working WiFi connection, but still no help. Share this post Link to post Share on other sites
wic.support 30 Report post Posted October 18, 2019 Good day. What exactly is happening? USB device does not recognized by system at all? Recognized incorrectly? Could not find appropriate drivers? Also, try to change USB cable and port first. Share this post Link to post Share on other sites
