Hi,

I'm wondering if anyone has experienced any sort of clogging issues
with the R2400.  I know that clogging was an issue with ink printers
when using pigments, like the 1280/90, but seeing the R2400 is
designed for pigments this shouldn't be a problem anymore, should it?
 How about when using 3rd party pigments like the MIS K4 set?

Thanks--
Jens
