Re: Can I use Epson 3800 M and LM cartridges in a 3880

The answer is "yes". I used chips from Epson OEM 3800 Magenta and Light Magenta carts and installed them in Inkowl refillable carts, which I then loaded into the Vivid Magenta and Vivid Light Magenta positions. Absolutely no problem.
The reason your Epson OEM 3800 M and LM carts don't work in an Epson 3880 printer is due to the shape of the carts; Epson uses physical blockers to prevent insertion of a 3800 M or LM cart into a 3880. It's not the chips that prevent this,.
