Chosen Solution

Please help. I have a WF7710 and want to use CISS . I haven’t installed these yet. I did update the firmware not knowing I should not have. Can you tell me if this firmware will prevent me from installing 3rd party cartridges. Thanks

A better solution (WF-7710 CISS cartridge) - this worked for me: Thanks to i.konstantinidis33 for the key combination for getting inside the recovery mode (power+status+4+7). Notes: the whole process was done with CISS module already inside printer !very important! make sure that the CISS module clicks firmly into place - after firmware downgrade the printer still didn’t recognize CISS module, but it wasn’t firmly attached - apply some pressure to click.

  1. Download Recovery Mode Firmware version FA27HC from epson site: https://epson.com/Support/Printers/All-I…
  2. Connect the printer to the PC only via USB cable.
  3. Power off printer.
  4. Enter recovery mode.
  5. Open Recovery Mode Firmware version FA27HC from PC.
  6. Press Start to “upgrade” / basically to downgrade firmware.
  7. When new firmware will be successfully installed you will see all the buttons flashing.
  8. Plug off printer from power then plug back in.
  9. Power-on printer normally. Done!

I paid 22 euros to have it downgrade with wic reset and it didn’t work even tho it said succesfull … I found a way to do it manually .. turn printer off and after 1 minute press status + 4 + 7 + power buttons all together and don’t let them go until you see white text screen. This will bring up recovery mode, connect printer to pc with usb and run Epson utility with older firmware and it will send it to printer. DO NOT TURN PRINTER OFF. when successfully installed you will see the never version of firmware installed and all buttons will start flashing. Unplug and plug printer. I got mine downgraded like that but still CISS wont reckotnize all cartridges, propably faulty CISS %#*@ Chinese manufacturers…. If I am doing something wrong and I am missing something let me know ..
