Which printheads failed to function adequately in the Mimaki JF-1631 and Oce Arizona 250 GT?
The same or similar model of printhead, used in both these printers, had similar issues. But not all printers had these defective heads. But I spent several hours with an accomplished printing company in Europe, and they showed me photographs of all the problems they were having. Another owner of the same model of printer, in Mexico, wrote to say he had comparable issues. And two owners of Mimaki JF-1631 and JF-1610 UV flatbed printers had similar issues. I discuss all this in the FLAAR Report on printheads for UV printers.
