How much flushing should one do when switching between UT-3D MK (Ebony I guess) and 
PK cartridges on Epson R200? Should I run a cleaning cycle, or just print X square inches of 
only black ink position (using a RIP)?

Many thanks for advice.

I'm told the heads contain very little ink.  Usually the cleaning cycle 
that is done as part of the ink changing will be enough when just 
switching between MK and PK.  

I know from switching from color to a grey, however, that there are 
trace amounts that will take a while to clean out, but I don't think 
they are enough when you're just dealing with 2 high load carbon inks 
to make a significant difference in actual printing.  With color one 
can often see traces in the top half of a purge pattern print.
