Digital BW, The Print

I had the same experience with MIS spongeless in 12x0 printers, most 
black carts worked well (except the occasional catestrophic leak 
problem) but few colour ones worked - 2 out of 6 I think.  At least 
one part of the problem seemed to be the fit between colour cart and 
printer, as I had a pair of colour carts that were bad in the first 
printers I tried, but just swapping them over to other printers made 
them much better.

OTOH a friend has had 100% success for over a year with one colour 
cart and one printer!

Sponge carts replaced every few months is less stressful, I think.

In the end the problems with these carts and a few co-incidental head 
failures pushed me away from several 12x0 to another approach 
entirely.
