WF-579R older chipless firmware

Recommended Posts

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!

You had working printer with the same firmware version when it started to print bad quality.
So it is hardware problem
Not Firmware
Firmware version has not been changed
I offer you to contact printer developer - Epson - to solve the problem
