Paul,

What kind of fluid can be used to clean a big 9000 CIS system of
all the dye inks that has been used in it ?
With a vacuum pump (+ a bottle in between) I can get all the dye
ink out and pull a cleaning liquid through the system and get it
more or less empty again but there will still be some cleaning
fluid or water left in the system. What actually triggers the
viscosity increase ?
