ricoh mp-c2500 lite copies at bottom

[ksp]

I have a mp-c2500 that is giving me lite prints at bottom of landscape or down left side of portrait prints. It seems to only do it when making prints, internals well as from a computer. the copies seem to be fine. It just does it when printing and is intermit. It could be the 2nd, or 5th, or 12th print. I have cleaned the charge roller, ID sensor, t&s roller, and the cleaning blade for transfer belt.
any help would be great, thanx Kevin

Remove shutter and clean laser optics. Proved to work.
