Our office looked at Canon, Ricoh, Konica and Xerox for our production color. What sold it for us was the ease of replacement parts that we can do without a technician. I mean, really customer replaceable, not like teaching a person to unscrew a few things and lift a heavy fuser like some on the Konica have suggested. Xerox makes it easy. As for quality, I don't know what everyone else is seeing, but the blacks and solid fills on the 700 are beautiful. How can Konica match 600 x 600 vs. 2400 x 2400? We also run a lot of 220lb paper and the only one that could handle it in the machine was the Xerox 700. We have had the machine now for several months and we have not had ONE jam when running the heavy stock through the drawers. Our old Canon couldn't even dream of doing that. We asked Ricoh and Konica but none of their machines could handle that weight. We do a lot of double sided and doing it in the drawer has saved us hours of work. The Konica and Ricoh were less money, but with the volumes that we do we can't afford to be down for 2-6 hours (depending on the time of day and when the call is made for service) to have a tech come out to replace a drum. Now we do it in a few minutes. To the two people that run our copy center, it is priceless to have it. Now we have happy employees that don't have to hear everyone complaining to them about how long the copier will be down.
All of them are great systems, so don't get me wrong, but when we looked at all of the items that were important to us, Xerox had the best solution and we have no regrets. We will not consider replacing the rest of our copiers to their 7400 series because of how happy we are with their high end color machine.
Just my two cents
