If the capping station seals perfectly to the head, there is only one way 
out for the ink vapour and that is through the plastic tube from the capping 
station to the waste pads - via the pump. Not sure how much the ink solvent 
would penetrate the plastic tubing, but there is no other way out - is 
there?

I would expect that if you are printing on dusty, fibrous, arty papers, the 
head is going to get covered in the dust and fibres which will prevent a 
perfect seal, even if the head does get its bottom wiped frequently. I would 
bet it is much less of a problem if you print on Premium Glossy!

As I said in another post, my old R2400 (with Epson inks) can sit for 6 
months without use, and only need one cleaning cycle for a perfect nozzle 
check. My 3800 usually prints perfectly after a week or two without use. I 
rarely bother to do nozzle checks unless I'm doing an important print. But I 
do live in a humid area, don't print on matte papers very often, and don't 
use 3rdparty inks.
