Well, I think with all these printers, their is the possibility of something going wrong. The more I use mine the more I see how sophisticated they are. The only problem i ran into so far was with very thick curly near the end of the roll printing. Once I increased vacuum and head strike distance it cleared some faint ink lines on the unprinted border of the image, which would only appear in the first inch or so of a new print. This was a quick fix and had nothing to do with any inherent problems of the printer. It was nice to know these adjustments are available for precisely this problem. For me so far everything is smooth sailing. Of course I have only been printing with it for about a month, so time will tell. I'll relay anything that might be relevant to others as time goes by.
