If you are using the Brother DCP-L2640DN printer and you see a message related to the drum unit, such as “Replace Drum” or “Drum End Soon”, it doesn’t always mean that the drum needs immediate replacement. In many cases, you simply need to reset the drum counter. In this guide, we will show you exactly how to reset the drum counter on the Brother DCP-L2640DN quickly and safely.
Brother printers track the usage of the drum unit through an internal counter. Once it reaches a certain limit, the printer will display a warning message. However, if you have already replaced the drum unit or you know it is still in good condition, resetting the counter will remove the error and allow normal printing. 
Your drum counter is now reset, and the error message should disappear.
