Epson firmware update over the Internet today to 30.74.CL27J9 caused the printer to stop recognizing the installed 3rd party cartridges. ???? Downloaded WIC, bought a firmware key, put the printer in maintenance more, ran the update ( CL26H9) which said it transferred OK to the printer. The printer seemed to run the firmware update but when it seemed to complete it displayed a screen that said it still has the 30.74.CL27J9 Powered on/off a couple of times, but no change, firmware is still 30.74.CL27J9 and ink cartridges are not recognized. Tried to re-run the process but WIC says it's already done it. How can I fix this? Thanks.
I am receiving this error when trying to activate on a WF-3720. The firmware was updated successfully but this error appears, have tried on two different computers and have the same problem. I did buy an activation code, order 17956338.
