no Steve, it's only printing half the width. The way it works it should print all the yellow in a pass, then the cyan, then the magenta. For some reason it's only putting the ink down across half the paper.
I'm not sure but I think dye sub heats the ink, if that's the case it implies there's something wrong with the heater. Having said that for all the size of it why it would need more than one element beats me
