There was problems with the IU's a while ago, but I agree with mrwho above....A simple clean of the K LED will most likely fix it. -
First try to wash the black printhead with a moist pad and then clean it dry. The reason why this could affect only one type of paper is because the machine adjusts toner density on heavier papers, so a dirty printhead could not show on heavier paper. If that doesn't work, try to swap the black IU with another (used) one to see if the problem changes.Leave a comment:

KM C450 black image problems
Hello Everyone,
I have a customer with a C450 Minolta machine, colour prints are fine but when we do 80gsm black only we get some halo's and smudging around the text.
thick paper setting seems to be unaffected, i have changed the fuser loop sensor as i have had that cause this before and the fusing unit is new.
anyone had this before??
cheers
