Replaced drums & toners, all OEM. Still light print on one side about 2 inches wide.

I suspect the laser unit needs to be cleaned but need the service manual to see procedure to get to lasers.

Anyone have the service manual I could get? I have all Konica Minolta manuals if someone wants to trade.

Tried googling but no success finding it. All downloads require downloading their installer, etc. Don't want to do that because of spyware, viruses, etc.

Thanks in advance
