the end with the pins and traces was first and that was were it stuck best
for I'm guessing the circumference of the drum after that it started getting
dropouts and low toner density and then picked back up near the end
for some reason
it may have something to do with the density of fill in those areas
the board outline was much darker than the fill area even in the
stripe with the lowest toner density and vertical traces and isolated
doughnuts seemed to do better than horizontal traces or connected fills
(?or that could just be a red herring? :)
