Does anyone have any suggestions for "mothballing" an Epson printer?

I have a 2200 that I want to keep (for backup or spare parts), but  
may not use again for months (or more). The concern, of course, is  
about the wet parts --- heads and related ink transport.

My initial thought is to replace the ink cartridges with MIS clear  
"base" filled cartridges, run a few cleaning cycles until the  
pigments are pretty well gone and then store the printer with those  
"cleaning" cartridges in it.  (I already have base-filled cartridges.)

Any other suggestions or experiences???
