Digital BW, The Print

I agree that air (or foam) and carts can be sources of trouble.  But, most
of us seem to get good results from the carts MIS finds.  Searching for the
best carts is clearly a significant job that MIS does, indirectly for us. 

If one does too many cleaning cycles it appears the printer tries to suck
out ink faster than the sponge can release it.  I speculate that the printer
then starts to pull air in around the intake.  

"Priming" the easy-refill carts is very important at first due to an air
pocket at the outlet that is only eliminated if there was a good, original
vacuum fill.
