I cannot speak to your specific printer, but we have an Anapurna Mv that will be 9 years old in December. Generally speaking, I think they are decent machines with some issues. White ink opens up its own set of issues, I am sure. Several things I would changed if it was my design, one being a sprocketed belt. Our belt, no matter how much I adjust it, twists more than I'd like, perhaps I just don't have the knack for setting it. Which makes it tough to back up a board when it twists 1/8 of an inch on a 8 foot board. Again, perhaps that is just me.Ours has had another issue since the beginning of a "Wait Data" error, it can be printing along fine, dedicated cable. Then it pauses with the said error on screen, sometimes it will pick back up, most times not, and will usually, if I don't get over to it quick enough, then fly over to the capping station end and hit the bumper pretty hard. Then it is a total new start over. The error was reported to Agfa in the beginning, and no real help was offered or suggested. The error can occur with any kind of file, from the simplest text only prints to complex images, and it is not repeatable.
I don't know about this model and the ink sets it uses, but ours is stuck using the first generation ink sets, and its ability to adhere to coro and plastic stuff on cut edges is not very good with heavy coverage. I'm working on a job right now with a black background with white type that I know will have to retouch virtually every one due to flaking ink on the cut edges.
The other issue I have with plastic media is static. On this same job with some large areas of black or dark blue, the static charge pulled cyan or black ink vapor out of the air into the white letters on more sheets of material than I'd care to count. Again, with our ink set, on smooth coro, if I wipe with denatured alcohol, and use light color, I can see every towel mark in the print job, or every finger mark. Perhaps the newer ink sets are better.
Maintenance is fairly simple, after the first year, we've done everything in house. We've done head change outs, ink lines, and managed to figure out other issues without having to bring in a service tech.
