  1. Activation code error, please, check, I get that error and I just bought the key for this is the second printer that I am returning it without a chip but you cannot enter the key in the previous one and it did not give me problems, I need an urgent solution Ver foto.
  2. Want to ask first before changing the firmware - Just acquired a WF-7720 (using 27 cartridge) through grey import but at where I live only WF-7721 (using T188 cartridge) is available... Will be using genuine cartridge as I am really after the pigment ink. After making chipless is it possible to use the T188 cartridge directly? Or is it possible to flash the WF-7721 firmware?
