Hmm, thinking about that, if there is a air bubble in the printhead the  
head itself has absolutely no way to pull ink in, other than gravity and  
luck, because the piezo head will not pump air... So the only way to get  
any air out is with a working vacuum pump and a cleaning cycle, right?

Seems obvious now, but i have never thought about it like that...

I will make up your soultion and use lots of patience with the next  
printer i get. It seems like you know what you are talking about....

No luck so far with the lintfree wipes. there are some medical cellulose  
pads on ebay which are supposed to be lint free, but i have severe doubts  
they are really lint free on the level i would need. I can get cleaning  
tissues for eyeglasses, but those usually are soaked in lotsa stuff that  
is meant to make them clean well and smell good.
