How to reset " replace drum" for brother MFC-7860DW


Time to really order a new drum and really replace with a new one.
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!

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.
6.Press Options.
To confirm you are installing a new drum, press 1.
7.When the LCD shows Accepted, close the front cover.
8.Your drum is now reset.

Says manual feed. Load paper


There is a manual fee slot just above the paper tray. Sounds like the manual feed slot isn't closed all the way. Here's a link to support for your machine: MFC 7860DW Others Brother Solutions Center Note there is a firmware update available.
