image0(5).jpegHi, I hope you can help

Up til a few weeks ago printing was perfect, but NOW there are black dots every inch on the length of every print page.

 

I have cleaned the drum (nothing there)

I have ran the tools > clean page

 

Neither had an effect, the small black dots are still there.

 

Any idea how to fix this?
