WF-579R older chipless firmware

[WF-579R older chipless firmware]

Hello. I have 2 WF-579R with chipless firmware, both with the same problem. Neither has yellow color working. Instead of yellow, printer prints black, sometimes cyan. And the pattern is blurry. I've done tens of cleanings but nothing will make it work. If I swap ink cartridges, for example, put yellow on cyan, after a couple o cleanings, cyan prints yellow, so ink cartridge is fine and ink is fine. Even yellow starts printing blurry yellow with yellow ink in cyan.

One printer got to about 20k copies and the other about 3k before yellow started to print blurry. So I was wondering if it's not a firmware problem.

Do you have a chipless firmware older than CE16L7 for me to try?

Thank you!

[WF-6090 Firmware downgrade unsuccessful]

Hello, I tried a firmware downgrade instead of disabled ink firmware (that bricked my previous printer), the process went through without errors, printer restarted but no firmware downgrade was made. Printer still has factory firmware, which is DG03K7 - 03/07/2020.

Can someone help me here? I've already spent $40 trying to make my printer chipless with no luck.

FYI, my orders were #24072262 and #24789104.

Thank you!

[Epson WF-6090 - Chipless Firmware and End of Maintenance Box]

AFAIK, you will need to update to official EPSON firmware for the printer to recognize new maintenance box and then, when installing chipless firmware again, it will ask you for a new key. So you only need one new key. You will need one key each time you want to upload chipless firmware to the printer.

[WF-6090 Region Change]

Do you know where can I get it?

[WF-6090 Region Change]

Is your 6090 Adjustment Program (EAI) EURO version? If not, where can I get it?

[WF-6090 Region Change]

Hi, my printer uses T748 (Latin America) ink cartridges. How can I change region for it to accept T9071 (Europe) cartridges?

Thanks in advance

[WF6090 Firmware update problem]

So, luckily, I sent the bricked WF-6090 back in warranty and got a brand new WF-6090. Now, does this chipless firmware work at all? Did I do something wrong? I won't try it again if I'm going to get the same result. Is the firmware compatible with South American model? What was the problem?

[WF6090 Firmware update problem]

Hello. As I've already seen on this forum, I had the same problem updating to firmware with disabled ink on my WF-6090.

Machine was updating firmware, then it shut down and never started again. I've waited 10 minutes unplugged and tried entering service mode using suggested combinations but the printer is unresponsive. What do I do now?

FYI, I tried to update directly from Epson's latest firmware. Later, I saw a forum post explaining that I was supposted to update to another firmware in WIC utility before going for the disabled ink firmware. WIC utility didn't warn me of anything and anywhere but that forum post said that I had to do that firmware upgrade first, so if that's the case, how should I know?

It would be really awful that I spent $20 just to break my brand new printer, so please, help me out.

Thanks

[Where can I get the maintenance box chip reset?]

Ok. I found where to buy. Resetter is on it's way.

Just to clarify, every time I need to reset the maintenance box chip I need to update the printer with original epson firmware, then reset or change maintenance box chip, then reflash chipless firmware? Is that correct?

[Where can I get the maintenance box chip reset?]

Hi, I've already bought chipless firmware for my WF-C5790 and it works quite well.

Where can I get the chip reset for the maintenance box as I can't find a link anywhere?

Thanks
