There are 3 relatively simple possibilities. The easiest to check would be to try a different toner cartridge. Most print quality issues on HP's are from the toner cartridge. Second possibility is the transfer roller. This is the rubber like roller that sits right under the toner cartridge. It should be mostly black, not mostly white from paper dust buildup. You can either remove and clean it or order a new one, they are cheap.
3rd and least likely is a dirty laser scanner. This would require a service technician to remove and clean. If the laser scanner is dirty you would tend to have one side or the other be lighter as the scanner does not get dirty evenly across it's surface.

3. Try repairing or reinstalling OS.
