Yeah, once I got that clog cleared, all was well. It still works fine, after several months. Probably the semi-steady flow of ink now keeps it from drying or reacting to the elbow material. I did notice another good quality CIS I purchased for an R260 actually came with a couple of spare elbow connectors.
thuglife, did you try the warm Windex treatment I posted? It sure cleared my cyan woes. Still working good and I've printed a lot of photos in the last week.
