Problem: Error codes or broken gears
Possible Prevention: Toner must be agitated in order to break up the clumps that form while the toner is settling inside the cartridge. Once a toner is installed, a motor, coupled with the toner’s gears and internal auger system, keeps the toner agitated. So don’t be afraid to give that toner a good shake right before installation. It might just save you a service call.
