For going on a week now, our office printer, Oki c5800ldn, is bleeding Magenta as almost a drop shadow. I've cleaned like EVERYTHING in the machine. Replaced the toner and drum, and it still shadows! Oki tech support didn't really help either. Anything that prints or blends with Magenta is affected, almost like it's not lined up properly. I have also run manual adjustments out of the menu. Restarted it to adjust it...NOTHING WORKS!

Help please! I'm getting desprite.
