M452dn prints with marks on the page

[SteveInTx]

My M452dn has splotches down the left side of the paper. The problem seems worse when I print a cleaning page. I looked at the toners and they seem to be clean and unscratched. If this helps, when I print a cleaning page, not only are there splotches, but the page comes out wrinkled. I don't know if these two problems are related. I know that toners are usually the problem, but these are real HP toners (we're an HP toner & ink dealer). I figured that finding this problem would be easy, but I could use whatever help the community can give me. Below is a scan of the cleaning page and what it looks like on an alignment page. 

Thanks,

Hi @StevelnTx,

This is definitely a fuser issue. Replacing the fuser unit will resolve this problem. Fusers are considered comsumables and they will have to be replaced every time they reach near the end of their life cycle. Otherwise, you may damage your printer.

Please be sure you order the correct one according to your country's voltages:
