Digital BW, The Print

Hello,

For some weeks I am printing with  K4 inks (Epson R2400)and Ink 
Republic CIS system.
I print daily, but the yellow head is clogged constantly. I don't know 
if the problem is the K4 yellow ink or the cartridge( I have changed 
it several times). Now I fix it,  warming up the cartridge and the 
tubes, with a hair dryer and it gets solved the problem for some hours.

Somebody that he use K4 inks with MIS cartridge can tell me if he has 
some problem with the yellow ink?

Thank you.
