Thank for your replies. there's some good stuff there.
Ifelton, concerning the 7000's. They are decent machines and fairly easy to use. They are rated at 75k-300K a4 sheets a month. We run mostly 13 x 19 which comes out to monthly duty cycle of 30k-100k. In addition, if you are running card stocks, that will decrease the duty cycle and require more service calls, especially on fuser rollers.
Between our 2 7000's, if we run 160-180k, they seem to run fairly well. Once we start getting to 200k, they service calls mount and you'll be seeing service at least 3-4 times a week. These machines are basically enhanced color lasers. I would not classify them as a "digital press"
the paper handling is very good up to 300gsm. Registration is good front to back. The color consistency is so-so, but we have ours in a large wherehouse, with some enviromental enhancements. I would imagine if you had them in a room with tighter enviromental controls, your color output would be more stable. But the color will drift, especially on lighter tints.
It's an OK machine if you are jumping into the digital market and plan on doing the majority of your runs on lighter stock. it could be a good fit. If you plan to use it as a heavy production machine, you'll find it a bit tempermental. If you get one, I hope you have a good relationship with your service provider and you may think about providing them a desk at your facility as you will be seeing them quite often. ;-)
We actually call one of the machines "the Princess" and have a tiara mounted of above the touch screen as the machine can be quite "moody". When we had Canon engineers out here to fix a problem on said machine, they were not amused with the tiara on their flagship product. I told them when they solved their problems I would take it down.
And to this day, the tiara still stands.
Hope that answers some your questions.
