Hi there,

Below are instructions that I have found from the internet. Hope that they will help.

• Open the front cover of the printer.
• Hold down the Go button for 4 seconds until all the LEDs light up. Then release the Go button
• Remove the drum unit and toner cartridge assembly.
• Replace the drum unit and toner cartridge assembly back into the printer.
• Close the front cover of the printer
• Your drum unit should now be reset
MFC / DCP PRINTER SERIES

1.Remove the drum unit and toner cartridge. Wait 1 or 2 minutes.
2.Replace the drum unit and toner cartridge into printer.
3.The error message "Change Drum Soon/Drum end soon" will continue to appear if the drum counter was not reset when you replace the drum unit.
4.To clear this error message, you need to reset the drum counter as instructed below.
5.Make sure that the machine is turned on.

For MFC users: To confirm you are installing a new drum, press 1. For DCP users To confirm you are installing a new drum, press the Up Arrow key

7.When the LCD shows Accepted, close the front cover.
8.Your drum is now reset.

Resetting the drum unit will not improve print quality. It only resets your drum and allows you to continue to print. You decide when to replace the drum unit not the manufacturer!

i have the same problem with my magenta drum unit on my oki c5550 the screen says missing M drum unit and the other errors i am getting are incompatible toner C,Y,K. how do i fix these

Some Brother laser printers have separate consumables - the toner cartridge and the drum unit. From time to time you may need to replace only the drum unit and not the toner cartridge.

The error LED lights up, or an error message shows on a flat screen panel, when the drum unit is near the end of its working life. Use the drum unit until you have a print quality problem, then replace the drum unit with a new one.
