I've sorted out the teething problems and I am now happily producing digital negatives with my 2400. I have a line on a lightly used 3800 for $500. I've looked around here and the reviews for this printer for making DNs seem to be mixed. Is anyone here successfully using this printer for DNs, and if so did you modify it? (remove the pizza cutters for example). This printer has no warranty, being used, and it is an attractive price for a wide format printer, hence my interest.
