Firmware installation issue with WF-7710
Error due to yellow ink cartridge recognition
License.exe will not see the WF-7710. Upon investigation I believe this is because the firmware installation cannot complete due to the error condition of the printer not recognizing the yellow ink cartridge, and that is why I want to install the firmware.
Troubleshooting steps taken
I have tried installing a new Epson yellow cartridge and the printer will not recognize this cartridge either. So I am stuck in the situation of an error I can't clear and that error prevents the firmware installation from completing.
Possible Solutions
- Change USB cable
- Change USB port
- Uninstall other USB printers
- Reboot PC
- Try on other PC or laptop
John's input
John, thanks for your suggestions. The install does work right to the point where it has the printer shut down and restart, so there's no trouble with the laptop communicating with the printer.
Next steps
I'm going to see about getting a replacement printer from Epson as my unit is still under warranty. Then I believe the firmware install will go through to completion.

Further issues and resolution
Still no go after following all steps, but eventually found a solution by using the correct USB port for firmware update.
Victory. I had no idea there was a second B type USB connection. Thanks for your help and patience.
