  Build the heater into the cart.  Paraffins melt in the 120-160 F 
range, well below many plastics.  Shouldn't be hard at all.  Even if the 
originals can't take the heat, there are so many clone carts that of 
course someone is using a higher temp plastic..

  Problem is the technology divide.  Epson has the mechanical piezo 
heads, which would likely be better for this.  But they're remote and 
permanent, would need seperate heat and aren't so easily replaced if 
something goes wrong.  HP has throwaway heads built into the cart, but 
IIRC they're resistive and use heat to move the ink, may not work well 
with an already higher temp liquid.  I need to see if I didn't throw 
away my Epson Stylus 800 yet, it'd be great to try with since it's a bit 
simpler being black only.  Still the seperate head but I won't care if 
it gets destroyed, that's if I didn't already toss it.
