I just bought an old jv33-160A. Previous users used sub ink to print heat transfer. I converted the ink system to PIG ink, replacing the ink chips on the ink tank continuously and printhead, filup to PIG ink. However, the print quality is not as good as JV33-130A new I bought earlier. It seems that the ink particles of JV33-160A are bigger than the ink of JV33-130A, or is discrete. Please ask, is there any way to adjust the smooth extrusion ink like JV33-130A? Or I have forgotten a single installation step?
