I use Staples multipurpose paper. I have the settings at 600dpi and "text" mode. I also make sure to always select the toner fixing. Not sure if I should select "thicker paper" - if that would work?
I have already tried to clean the drum unit. Not sure if it is the toner but I am going to call and see if they will replace. My fuser and drum unit still have 92% life so it shouldn't be going bad... :/ |
