sorry--I'm just running b/w in the printo, so I can't really help you with the RA4 only to say that the physical set-up of the machine is the same...
RA4 should last for a week or more in it if you replenish it though. It only holds 2000ml of chemistry in each tank, so could be you won't even put enough through it to really matter. if it doesn't oxidize, you might be able to stretch it out for a couple of days, but I'm not sure what the carryover from the dev would do the blix. I don't know if it would throw the pH off too much if you didn't replenish. The tanks are really well sealed though--when you shut it down you leave the lid open overnight so condensation doesn't form, or you can pull the lids as well--but I hated to do this....I got a week and a half tops out of unreplenished machine chemistry like 2150XL and could do longer with replenished LPD and Rapid Fix A. With something like 2000RT, I could have gone for weeks on end, but I wouldn't have had enough throughput to really replenish it right. It wasn't cost effective for me to have it set up as replenished compared to just using the chemistry to exhaustion. But I still got quite a few days out of it. I managed to put a couple of thousand 8x10s through it in a year--this is just for myself, messing around at home...
fwiw--the Printo comes with a nifty little parts packet, and it has most of the gears and springs and stuff that you would need to do a minor repair. I had a gear bust a couple of years ago, and it was piece of cake to fix. I think it's well made and designed piece of equipment, even though it's like a "junior" roller transport processor. The only thing that's going to go wrong is those energy-therms or the energy-mot's (or whatever they're called). The rollers would probably eventually become pitted and might fall apart, but there are no pumps or auto-replenishment sensors or anything computerized to really worry about. If a spring lost it's tension, you could probably find that pretty easily or make a replacement. It's not as complicated as some of these biger machines though, it's really pretty simple. You could probably actually stockpile an extra tank and energy-therm and parts kit as a backup and be set, if you were set on using it for years to come.
I just burned out at the end of the year with the processor at work, and so when the printo started acting up I put it away....I'm kind of sick of dealing with busted gears and bad rollers and all that, and wondering what that "thud" I just heard in the bowels of the machine was, or why there are streaks in the image and etc. they all seem to break down sooner or later, especially in the middle of a big project or on a tight deadline.
jobo has a schedule for phased out support of the various durst printo models, so could be you can find a decent used one that's still supported and save some money. I can't see there being a real big market right now for any of these things though, with a printo or a fujimoto targeted at advanced amateurs or small labs--they cost about $4000+ new (as the full unit, only about maybe 1500 for the basic set-up on a printo, funimotos are in the 3500-5K range). Think of the competition there with inkjets and dye sub printers and even Pictro printers...I think the days are numbered for all this stuff, sorry to be so pessimistic, but good luck all the same.
