I have an Xerox 8825 plotter and can't seem to plot my raster files at halftone. I insert my raster image on a scan layer and assign it a color. I then edit my ctb file to screen that color. I have tried changing the greyscale on/off, changing the color to black/object color, loading plotters with different drivers from xerox. I even tried plotting using the xerox as the system printer (which was worse). I am at the end of the line. Does anybody out their have any suggestions.
