Drum unit 6
Order No. DR-110CL
A new drum unit can print approximately 17,000 A4 or Letter size single-sided pages.
Note
• There are many factors that determine the actual drum life, such as the temperature, humidity, type of
paper, type of toner used and so on. Under ideal conditions, the average drum life is estimated at
approximately 17,000 pages. The actual number of pages that your drum will print may be significantly
less than this estimate. Because we have no control over the many factors that determine the actual drum
life, we cannot guarantee a minimum number of pages that will be printed by your drum.
• For best performance, use only genuine Brother toner. The printer should be used only in a clean, dust-
free environment with adequate ventilation.
• Printing with a third-party drum unit may reduce not only the print quality but also the quality and life of the
printer itself. Warranty coverage does not apply to problems caused by the use of a third-party drum unit.

you replace the drum unit with a new one before there is a noticeable deterioration in the print quality.
