Digital BW, The Print

I use Cone PiezoTone inks in my 1290 (european 1280) with MIS  
spongless carts. This works OK regarding to clogs and need for  
cleaning cycles. I think maybe this printer will work even better  
with Cone K6/7 inks wich I have heard may give completely troublefree  
operation. People report that their problems with clogs have  
dissapared after switching to K6/7 inks. If there was 1290 user among  
these users I don´t know and printers  of the same model may behave  
differently regarding to the same inks.  To conclude I personally  
would go for Cone k6/7 inks if I started out with a 1290 now. - And I  
am going to try Cone Sepia K6 soon...
