Digital BW, The Print

I recently experienced this kind of super major clogging with an Ultrachrome Mk channel in a 9600 that hadn't been regularly used in a year and a half. The only thing that worked was the fantastic pinkish flush fluid that Cone sells at inkjetmall.com. This stuff really works and is a fantastic solution to keep in the lines when printers are not being used. I use it also when switching from one inkset to another. I was able to even flush this particular machine out without replacing the damper. I will replace it though before loading it up again. 

The problem with any carbon black channel is that if it isn't used regularly, the pigments eventually separate from the base and will clog not only the head and lines, but also especially the dampers, those filters that filter impurities from the ink tank to the head.

Cone also sells dampers for some of the older Epson printers. I highly recommend everyone finding some source, Epson or otherwise, for a complete set of dampers on all of these machines, especially the black and gray channels. Constantly doing power cleaning and nozzle cleanings on a super clogged printer can bend the metal grid on the surface of the head. After that they will never be the same.

Finally, it is also very important to shake the ink carts every week at least with these kind of inks. But letting them sit like that will cause problems regardless.

Several head cleans later and all the Epson cartridge ink channels work fine.  But of course I have Eboni in the K slot and it's still dead.  There doesn't appear to be any room under the head to do the windex trick.
