WF-7620 chipless firmware questions

Recommended Posts

Greetings,

I own a WF-7620 and I seeking to convert it to a chipless printer using the WIC tool. However, I hope I can have the following clarified. The link below shows a table of supported Epson printers:

https://chiplesssolutions.com/support.shtml

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?

Additionally, on the website link below:

https://www.2manuals.com/product_info.php?products_id=1149

The notice shown below appears about my WF-7620:

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

What does that mean?  Does it mean the WF-7620 chipless firmware is not working at 100% ?   I ask because nowhere in this forum thread can I find a clarification on the bold notice shown above.  I hope somebody in this forum can explain what possible limitations exist.  Will I still be able to Scan and Fax if I install this 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.

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:

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.
