Benjamin,

If you are replacing MIS inks with the original Piezo inks, you don't 
really need to flush your system out.  Just put in the Piezo 
cartridges, and clean the nozzles until you get good patterns.  Then 
you are ready to print.

If you are about to put in the new PiezoTone inks, you will have to 
flush the system out.  Just put the flushing carts in the printer, 
and print a number of purge patterns (which can be found at the MIS 
website for download, or even at the InkjetMall site).  And, yes, the 
puge bars should be color and you should be using the Epson driver 
for that.

After that, the next step depends on whether you are using CIS based 
system or cartridge based system.  For the former, you really should 
get a new set of CIS cartridges.  If you are using cartridges, once 
your system is flushed, you are set to go.  Just make sure you are 
getting clean nozzle checks.

Good luck.
