Digital BW, The Print

I have to agree with Martin and Paul about getting new carts for 
your CIS when switching inks. Alas, I did it the cheap way -- just 
swapping from PiezoTone WN to MIS FSN in my 1280. I ran a bunch of 
purge patterns on 11X17 cheapo paper until the tone color 
stabilized. The problem? Where I rarely had to run cleaning cycles 
before the swap, I now need to run one or two cycles at startup each 
day. I don't think this can be attributed to the MIS inks, either. I 
use the FSN inks in a 2000P and I haven't had to run cleaning cycles 
in weeks. Fortunately, after the 1280 heads are cleaned there seems 
to be no additional problems with output. However, I'm always 
worrying and wondering. I think new carts would alleviate much of 
the worry.
