I have been using the printer for over a year and have only had to clean the nozzles once in that time. I have the impression that the printer maintains itself very well and economically. The tanks are incredibly plentiful. I can recommend the printer with a clear conscience.

I only use it once every 2-3 months and then always have to clean it several times to get acceptable results again. Or do a "power cleaning" right away. (Takes about 10 minutes, but needs a lot of ink).
So it depends a lot on the application profile.
