✒Note

∙When removing the drum unit, handle carefully as it may contain toner.

∙You should clean the printer at the same time as you replace the drum unit. See “CLEANING THE PRINTER” in this chapter.

∙Discard the used drum unit according to local regulations. If you are not sure of them, consult your local dealer.

Follow these steps to replace the drum unit:

1.Unplug the printer.

2.Remove the multi-purpose sheet feeder. Remove the toner cartridge and keep it in a safe place.
