Drum Unit - Brother HL- SERIES User Manual

Routine Maintenance

Drum unit

A new drum unit can print approximately 12,000 A4 or Letter size single-sided pages at 1 page / job.
Note
• There are many factors that determine the actual drum life, such as the temperature, humidity, type of
paper, type of toner used, number of pages per print job and so on. Under ideal conditions, the average
drum life is estimated at approximately 12,000 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 machine should be used only in a clean, dust-
free environment with adequate ventilation.
• Printing with a non-Brother drum unit may reduce not only the print quality but also the quality and life of
the machine itself. Warranty coverage does not apply to problems caused by the use of a non-Brother
drum unit.
DRUM END SOON
If the Drum LED flashes, it means the drum unit will need to be replaced soon. We recommend that you
replace the drum unit with a new one before there is a noticeable deterioration in the print quality.
