Brother MFC-7240: How to Reset the Drum Counter

Whenever you replace the drum unit in a Brother MFC-7420 laser printer, you must reset the drum counter. Otherwise, your printer will continue to show a “replace drum” error and you won’t be able to print! Here’s a step by step on how to do it.

Step by Step:
1. With the printer’s front cover open, press CLEAR.
2. The printer will display, “Replace drum?” Press 1 to confirm you are installing a new drum.
3. After the display shows “Accepted,” close the printer’s front cover.

That’s it. Enjoy your new drum!
