Am currently troubleshooting a CLJ 4600dn that is jamming in the fuser. Documents with graphics requiring dense toner levels continually jam, however, normal documents (word documents or light graphics) are printing just fine. I just replaced this fuser due to the previous one getting a tear in the fuser. I am replacing it tomorrow, but have a feeling its not going to resolve the issue. Its just too weird to me that simple documents are printing properly, but the dense, complex ones are not. One thing I realize I didn't do is a full calibration after replacing the fuser, but not confident that will help either, any suggestions?
