After you replace the drum unit on the Brother MFC-L2750DW, the printer keeps showing a drum warning until you reset the drum counter manually. This step-by-step guide shows the exact button sequence to perform a Brother MFC-L2750DW drum reset in under a minute — no tools or service menu required.
Reset the drum counter after installing a new or reconditioned drum unit, or when the display shows “Replace Drum” or “Drum !”. Resetting tells the printer the drum life is full again so the warning clears. It does not clean or repair the drum — it only resets the counter.
You can watch the full procedure in this short video for better understanding:
If the Drum Reset option does not appear, make sure you are holding the Toner icon and not the Cancel button, and that the front cover is fully closed. If the drum warning returns shortly after resetting, the drum unit may be genuinely worn and need replacing.
No. The reset only clears the counter. If you see streaks, spots or faded print, the drum unit itself may still need to be replaced.
No. The toner reset clears the toner message, while the drum reset clears the drum counter. See our Brother toner reset guide for that procedure.
Only when you replace the drum unit — roughly every 12,000–15,000 pages, depending on how you use the printer.
