Can't reset 7880 waste tank chip

I emptied & cleaned the 7880 waste ink tank but I cannot reset its chip. The resetter blinks red and then goes solid red. I did reset an OEM ink cartridge OK. I have the USB resetter. Do I need a replacement chip for the waste ink tank? I think this is an Epson tank but there is nor printing on it.


Occasionally, waste tank chips can go bad and unable to be reset. Out of about a dozen waste tanks that I’ve been resetting/reusing over the past +/- 8 years with many printer models, I have only had one waste tank chip fail. I believe the waste tank chips are different from the cartridge chips (though I haven’t tested/confirmed this), so I ended up discarding the tank with the bad chip and used one of the others I have.

I hope this helps~ Dana
