Drum life is approximate and may vary by type of use.

For best performance, use a Brother Original drum unit and Brother Original toner units. Printing with a 
third-party drum unit or toner unit may reduce not only the print quality but also the quality and life of the 
machine itself. Warranty coverage may not apply to problems caused by the use of a third-party drum unit 
or toner unit.

 

The corona wires are coated with paper dust or toner. Clean the corona wires in the drum unit (see Cleaning 
the corona wires on page 160).

The drum unit is nearing the end of its rated life and will require replacement. We recommend you keep a 
Brother Original drum unit ready for installation. Buy a new drum unit (DR-321CL) and have it ready before 
you get a Replace Drum message.

The drum unit has exceeded its rated life. Please replace the drum unit with a new one. We recommend a 
Brother Original drum unit be installed at this time.
After replacement, reset the drum counter by following the instructions included with the new drum unit.

We cannot guarantee the print quality. Please replace the drum unit with a new one. We recommend a 
Brother Original drum unit be installed at this time.
After replacement, reset the drum counter by following the instructions included with the new drum unit.
