REPLACING THE DRUM UNIT
The printer uses a drum unit to create the print images. Check the print
quality. If there has been a noticeable deterioration in the output print
quality then the drum unit should be replaced.
✒
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.
See the chapter “REPLACING THE TONER CARTRIDGE” for more
