Re-invented is almost certainly looking for a single process system with no human interaction needed after telling it to make X copies, with ready-to-use discs turning up at the end.
As this is for the marketing department, and it is intended to be used a lot, a rapid on-site repair service is even more essential, I'd say. A large disc capacity would also be important. I'd be wary of reseller websites which don't offer you warranty and repair contract details.
I did a quick google search, and found Verity systems, the name of which is ringing very big bells for me. Their robotic systems are by no means cheap, starting at £3000. However the build quality looks very good, their systems are designed with multiple burners, and most importantly their warranty is on-site and I strongly suspect it should be possible to find professional support contracts for their kit.
