Good morning guys, we just recently bought a lx850 and i cannot print solid colors, unless its yellow or black, without getting heat marks every once in a while and banding. I have called techs from HP and outside techs and they say nothing is wrong with it it is just the "nature of the beast". But we have 2 L26500 and they print solid colors really good. Is anybody else having any problems with the solid colors on the lx850? i tried slower passes and messing with the temperature but it does not seem to phase it all.
