  1. The only difference here is during the writing of the initial settings, if this operation is used application will set region to europe in the eeprom and default paper size to A4, everyting else is the same. Additionally error codes usualy indicate mechanical malfunction and this looks more like firmware failure, try to update firmware from the official epson site before doing anything else (in normal mode first and in service mode if it will not work).


  2. Good day.

    In order to restore standart behaviour enable recovery firmware option in the settings (main menu > file > settings > Show Firmware Options for Recovery Mode) then select the firmware in the new list and flush it to the printer (those are free).

    Unfortunately, WIC version of the firmware most likely has been blocked for your device, you need to use CS version. You may replace WIC key for the CS key by paying the difference here:

  3. For my WF-7620 the table shows  "AD21G7"  for Required Firmware Key.  And "NA" for Activation Key. Can anybody please clarify what the "NA" is about?  Does it mean it is free for me to use this chipless software on my WF-7620?  And is the "AD21G7" still a functional Firmware Key?

    This means that chipless firmware for this model is only available in the WICReset and it is not supported by Chipless Solutions.

    This firmware is not free and AD21G7 is actual firmware version, not a key. You need to use keys from there:

    The notice shown below appears about my WF-7620:

    "The reset and read counters function are NOT available for this models (adjustment functions only)."

    Some printers has a chip on the maintenance box and for those printers software reset is not possible at all. This has no direct relation to the chipless firmware.

    Lastly, I still need to buy third party refillable ink cartridges for my Epson WF-7620 printer.  What is the correct refillable ink cartridges I can buy that will help the WIC firmware in working problem free?  Any advice that points me to the best online store I can buy the correct third party refillable ink cartridges from will be greatly appreciated.  Thank you for your time.

    If you will be able to install chipless firmware it will work with anything that you can install in the printhead, it will even work without any IC at all. Unfortunately I do not have specific advice about what store will be the best for your country or which IC to use.
