Series of equally spaced dots on my printed documents from Canon LPD7660Cdn laser printer

I am suddenly seeing an equally spaced and sized pattern of black dots down the right side of my printed documents and 2 columns of dots also equally spaced and sized down the left side.  What is causing this and how do I fix it?

 

Thanks

Yes, I've already tried cleaning the Fixing Roller.  Still have the same issue.
