Had an original one of these (branded eprint 1000) way back in the day, ran it for 3 years it came with HDI (hi-res imaging) the maintenance can he around 1/2 hour per day, changing pips and blankets is not too bad, the separator was a nightmare. Keep away from the duplex,, do it manually, front back registration had to be played with to get anything decent out, duplexed business cards 21-up were a nightmare. I would suggest core branded paper, we had problems with any other paper above 300gsm. Also the air con was prone to problems (could be just mine I suppose). If looked after then the quality was quite good in it's day. Try and see the machine running for at least half an hour or so - make sure that the separator is cleaning as it should be and also be careful if the tank filters have been removed, the engineers back them used to remove them if you were doing quite a bit of printing, but if they have been removed and the machine has a low print count then stay away.
