I ran the 700 for about 4 years and I have to agree with everything tech said. It's a good printer when everything is running well and you're using it on a regular basis. But, let it sit idle for more than a long weekend, or when things go wrong, they can go wrong in a really bad way.
During my time running the printer, we maintained a $2,000 per year service contract on it and it paid for itself, and then some, every year. In 4 years, I maybe bought a dozen print heads. Fortunately, their fairly cheap. The rest were replaced under warranty. The issue with the warranty claim forn is that it took 30 minutes or more and about $5 in materials to properly fill out the paperwork and do all the test prints. Then you had to pay for shipping. When you're replacing 2 or 3 a month, those figures add up quick.
Depending on how often you run the machine, the bushings needed to be replaced every 6-10 months, a 3-4 hour job by itself by a trained technician. We would average 2 additional service calls per year for "other" repairs and all the service calls averaged between 4 and 5 hours.
Daily maintenance wasn't bad, maybe a 5 minute wipe-down with a damp rag. Weekly cleaning and maintenance took about 30-45 minutes and Rapid Prep worked great!
You can print directly to it from some software applications, but it can be a time consuming process that will eat up the resources of the computer. So, I would suggest a dedicated work station with RIP software to make production a lot faster and easier and produce better looking prints. This should be SOP for any large printer.
With all this being said, I think you probably would be better off with a used solvent printer. It will cost more up front. However, the long-term costs, care and maintenance issues will be a lot less.
