I have one of these Epson Multi function printers. Epson DX9400 Fax I am having a problem with the black printing. The other colors are fine (Cyan, Magenta, Yellow) and the problem occurs only when I print, photo copies print black just fine which is the reason I am stumped. I recently purchased some 3rd party cartridges to save money and this problem started. Well I thought that the cartridges were defective so I got some original Epson brand and the same results. I've tried head cleaning several times and same thing with both cartridges which I know are good because the copies are just fine. It's only when I send a print to it that the black does not work.. Anyone have an idea on what to look for or is it time to chunk it?
