I just installed a set of cartridges with the Piezo Pro inks. Two of the cartridges weren’t recognized (PK and LK). I tried reseating them several times. I also tried going through the full reset process described on page 4 of the instructions. None of this resolved the problem.
I have a second 3880. The new cartridges are recognized in it, but the Epson ink cartridges aren’t recognized in the converted printer.
I did have some problems with seating the controller chips and wonder if I damaged the contacts on the converted printer.
Is there a way to check this out?
