If you notice spots of toner on your printouts, there are several possible causes. It could be due to a dirty pre-charger, in which case you should clean the pre-charger. Another potential cause is a dirty developer unit, so cleaning the developer unit may resolve the issue. If neither of those steps works, try replacing the toner cartridge.
