Digital BW, The Print

Evening all

I have just this evening got some UT2 inks in a CFS installed in a
1290 printer. I am using the 1280 driver and everything looks good so
far. Very impressive indeed, even on glossy paper. My question is that
I am going on holiday for 3 weeks on Saturday and I have read about
the nasties that happen if you leave it unattended for that long. 

What should I do to prevent this? I think my best course of action is
to  put the Epson cartridges in, get a good nozzle check and purge the
printer so that the head is full of Epson ink, then go off on holiday. 

What do people think of this? Is there a better way?

Thanks for any input on this.
