xerox phaser 3600 leaving marks on paper

[jviehe]

Is it a solid line down the paper? If so, then its probably the fuser that needs to be replaced. If its a repetitive mark every few inches, then its probably just the toner drum.

The printer is leaving marks on the paper going down the middle. Can i clean the printer or should i order new parts?
