Hi @Admin, I have WF-2850. After running FIRMWARE, my printer shows "BL05K3". But the FIRMWARE Program says could not be updated. Is this the right firmware? Can I now activate online? I don't want to purchase because it says Non-Refundable. I want to make sure this is the correct Firmware.

Hi! It's the WF-2850. I ask because someone in my family may have updated the firmware to the latest. Hoping this wouldn't be a problem.

Hello, before I install the INKCHIP Firmware, does it matter what firmware the printer is on right now? Thanks!
