One thing that comes to mind is that some of the ink bottles may not 
be vented to atmosphere and you are getting a vacuum after a couple 
of printouts. check the hole in the top of the bottle and make sure 
they are all clear.

the other thing is that these systems are very sensitive to proper 
filling on the initial setup. when properly filled you have to let 
them rest overnight before using so that any air in the sponge 
dissipates. did you follow the filling instructions TO THE LETTER? 
you can't improvise or second guess the instructions. also, you 
cannot let this system get dry. i try to remember to print something 
every day even if it is only a purge pattern.

i have been using the MIS cis system with good results on the same 
printer.
