I have KM Bizhub Pro C500 machine but I have problem with fusing. If the page has full colour it dosen't fuse it or mostly it gets jam at the fuser so I registerd 20lb. paper as "NORMAL 5" which is ok and no jam so far. But if I print on 80lb. glassy paper some spot or one side usually dosen't fuse. I tried all the option for paper registration COATED and NORMAL but still dosen't work. I did fixing adjustment with Cyan density set up 88 but I don't have the chart to compare and I'm not % 100 sure if I did it right. My fixing roller are new. Any idea or suggestion? By the way I did changed the fixing roller but not the ball bearing. Is that can cause the problem? Thanks.
