Canon ImageClass MF726CDW Prints Vertical Yellow line on the left side of the page

[patrocle]

I have the Canon ImageClass MF726CDW and it Prints Vertical Yellow line on the left side of the page.

My i had the printer for 2 years and had no problems printing, with same type of toners.

Now for the last few weeks it started to have those vertical yellow line, is not a line, is like 1 inch wide line on the left side of the page...

Here is a picture:

I pulled the toners out from the tray and the yellow toner is the last one, and i am seeing some yellow mark on the big belt or whatever is called that i guess paper goes on it, i clean some ,but i can not turn it, from the front of the printer, unless a back cover can be taken of and have easy access, and also how to release the belt so i can manually turn it and wipe some .

What you think it maybe?

Thanks for any advice.
