Drum is probably beyond replacement time. Cleaning the charge unit may get quality back.

Hopefully not generic.

660k You may need something replaced.

Those 420-501 charge coronas are fragile. A single tiny plastic pin with the tension of 2 wires.....not a good combination.

And the way these machines mist you have to keep both coronas cleaned.
