    I am constantly fighting toning problems on my 3304h. when the rollers are new it prints beautifully but within 4-6 months the toning in the corners starts.
    the longer the run the dryer the edges of my plates seem to run. I used to think the dampener rollers just didn't hold up well but now I'm wondering if it isn't the swollen ends of the form rollers damaging the plates
    any thoughts?
    does anyone know of any steps I could take to keep the form rollers lasting longer before the start to swell on the ends?
