Replacing the Drum Unit

The MFC uses a drum unit to create the print images on paper. If the display shows CHANGE DRUM, it indicates the drum unit is nearly at the end of its life. We recommend you prepare a new drum unit to replace the current one. Even if the display shows CHANGE DRUM, you may be able to continue to print without replacingthedrumunitforawhile.Ifthereisanoticeabledeteriorationintheoutput print quality even before CHANGE DRUM is shown, then the drum unit should be replaced.
