Hello again,
It’s been a few years since I’ve asked, any updates on the WF-4830?
I can dump anything you need from the printer if needed (if you don’t have the printer), I might even have the tools needed if you need to read/dump the bios (or whatever you use to read / change the cartridge checks) by solder points. I also micro solder / I’m good in assembly code and reverse engineering software programs.
let me know if somehow I can help to finally stop buying these expensive cartridges.
