Paul,

What is the risk of technical grade glycerols bringing 
fungi/bacteria in the ink mix ?
A friend had that kind of trouble with MIS 7600 inks in two 
9600's at some point and we solved it by filtering with 9000 
damper sieves and adding some drops of fungicide.  I don't know 
whether that base was glycerol but it is likely to be similar.
