During the process of changing a Brother DR3300 drum unit a prompt must be given in order for your printer to recognise the new drum unit. Giving this prompt resets an internal counter allowing you to use the drum unit for an estimated 30,000 more prints. If however this entering of this prompt is forgotten when installing a new drum unit then a “Replace Drum” message will continue to be shown on the screen. Thankfully the drum counter reset can still be performed after installation.
Will this counter reset work for my printer?
The drum counter reset described below will clear “Replace Parts Drum Unit” error messages on the Brother DCP-8250DN, MFC-8950DW and MFC-8950DWT.
How do I reset the counter?
- Press Stop/Exit to remove the error temporarily.
- Press Menu.
- Use the arrow keys to find Machine Info and then select it.
- The select Reset Menu.
- Now select Drum.
- Then select Reset Drum?
- Select Yes.
- Finally press the Stop/Exit button.
The “Replace Drum” message should now have disappeared allowing you to continue printing.
