I've been reading this thread and similar ones re clogs and filling 
problems with CIS.  There is a better way. Have a look at my top-off system 
notes.  It works great - never a clog, well, hardly ever :-)  I use MIS pig 
inks. It's air not clogs most of the time  that causes 
problems.   http://www.panoramacamera.us/m_topoff.html
