I seem to remember a setting like HQ or LQ on that model that made it print more slowly (if you can imagine that), more loudly (if you can tolerate that), and more accurately. It could be that the ribbon is wearing out or misallinged with the pins. A little light cleaning of the print carriage might help. I know this definitely happens more often and more severely with color than black, since the strips of each color on the ribbon are so thin.
