Epson C82 using DuraBright ink, about half time text prints, half time photo prints. About 3 years old, never had a clog, but slowly going broke buying Durabrite ink carts. Took a chance and replaced the black, cyan and yellow cartridges with 3d party carts from Rapid Fill, a storefront operation that appears to be a chain. The sales guy said Rapid Fill ink would work fine in the Epson. However, within a week the print head was clogged using yellow and cyan carts, and no amount of "clean cycles" helped. The clerk at the store denied any knowledge of any incompatability and suggested it was a printerhead problem. I hit the net and found this forum and discovered the sensitive and clog prone nature of this printer if you dare to use 3d party dye based inks (which Rapid Fill is); and how to disassemble the printhead and clean it all out with an inexpensive cleaner kit (a nod and a thanks to fixyourownprinter.com). I took out and flushed out the printhead, flushed out the suction tube, installed new DuraBrite ink carts, ran a few clean cycles, and all is back to working perfectly. I went back to the Rapid Fill store armed with some copies of some of the posts from this forum and after some arm wrestling from the clerk who still denied the ink was the problem, got a refund for the cyan and yellow carts (interestingly the black Rapid Fill cartridge has never clogged so i assume there may be a difference between black and the colored inks). This post is mostly a "thanks" to the forum and members for all the good info, and also an inquiry on whether anyone else with an Epson/Durabrite combo has found a compatible 3d party ink?
