Digital BW, The Print

Hi,

I've just started converting my r2400 from Epson OEM inks to MIS K4
refillable cartridges (spongeless). My first set of carts I bought
prefilled and have just run out of OEM ink and have begun to switch
over. I am suddenly having clogs/dropped jets and ink spots on prints
since I have switched (I've only partially switched at this point).
anyone else had these problems? I've not had a single problem with
OEM ink carts....hate to switch back because of the costs but I've
already wasted a ton of ink just trying to fix the clog..
