Paul,
I am using IJM Cone Color pro ink with the IJM cartridges. I bought the printer, cartridges and ink nearly new from an estate. I have had no issues with the cartridges in the 18 months I have been using the printer, I have never had any problems with IJM carts. My B/W Variable tone 3880 is about 6 years old and still plugging away with the origin IJM carts.
I did once try to run some prints through my OEM ink 3880 ABW with Arches. The result was not acceptable.
