check the print quality, and if you are satisfied, it is not necessary to immediately replace the drum car-

tridge if the print quality is unacceptable, or replace the drum cartridge when you replace the toner
cartridge.

necessary.
* If you continue to use the drum cartridge without replacing it, the print quality may suddenly worsen, or
the unit may malfunction.
