Haven't had any 'oops put the hose in the wrong bottle' events and the drum is rinsed and dried after each run. I'll have to check on the replenishing particulars for what I'm doing. I figured I'd run through a couple boxes of paper and a kit of chemical just getting everything down pat before getting into the other details.

A roller transport? Hey man, that's cheatin'. But how in the world are you controlling/battling dust well enough to print 400 in a week?

Dust is enemy #1 for me. Dust never sleeps. It makes me craaaazzy!
