Ecotank-2600 invisible prints

[Greench]

Hi there!
Am I on the right forum for maintenance and repairs?
I bought this used printer a while ago. It worked fine for a hundred pages or so.
Then blue stopped printing and I messed with the printer, cleaning, flushing, disassembling, etc.
The printer seems to work, no error messages, but no ink on the paper.
I tried replacing the print head, replacing the main board, purging the tubes and cartridges.
What could it be?

Also, rumor has it there's an adjustment program for Epson printers after parts replacement, but all the programs I found online were virused. Anyone has a clean version of it?

Cheers

I'm not clear what you expect from this adjustment program in the current situation, there is nothing to reset at this point of time. Since you apparently did about everything you can do I rather would dump that unit.

Epson has been putting up some AIO printers in their Clearance Center of the web-store lately. Check often as they come and go quick...

I've read somewhere that the main board needs to be configured with the serial number of the print head, but I don't remember if that was for my model...

Thanks @bluestang , but I'm not in the U.S., it won't let me buy.
I'm giving up.
