Toner coverage variation

I have a Phaser 7100 which recently has started producing poor quality prints. 

 

For example this was the quality of one print.

When I printed a page out of just that colour I noticed that there's a variation in toner coverage from the left to the right (as the paper goes through LEF). It's more noticable when I tear the page in half and top-tail the page ....

I've done the usually maintenance and the toner cartrigdes have not been in that long. I even covered the printer with a cloth to try and eliminate light entering the printer. There's more direct sunlight to the left of the printer, but covering it made no difference. 

 

Any ideas? Where do I go from here?

Re: Toner coverage variation

Thanks for the help. I have calibrated and I am still seeing a difference between the left and right  edges of the printed pages. The toner coverage on the left of the feed is noticably different to that on the right.
