The scanner needs to be reset. Turn off the device and then turn it on again.
Please note that when you turn off the MFC's power switch its memory will be cleared. To check whether the MFC has faxes in its memory, click here.

Brother MFC 7420 change drum soon light, did, still says change drum soon, how do I rest the drum, I cannot find my manual. Tks


Simply open the front cover.

Press the Options key on the control panel.
The display will show "REPLACE DRUM - 1.YES 2.NO".

Press 1 to reset the drum count.

Close the front cover.

This procedure wil work on the majority of the Brother MFC series of laser based Printer Scanner Fax Facsimile machines.

Good Luck and Thank You for using Fixya

I get a SCANNER LOCKED error message on my brother MFC-7420. The manual says to turn the unit off and back on but that does not clear the error. I can use it as a printer but cannot scan or copy. There...


leave it on for a couple minutes and turn it off for a couple minutes, and try again, if still does it, you are having a problem with the scanner not properly going to home position. it will need to be repaired.

Model - MFC-7420 - FUSER ERROR


Is the paper that comes out of the paper warm or cool?
If "cool", then the fuser is not operating.

The job of the "fuser" is to generate heat to melt the powdered-ink into the paper, to make a permanent bond.

So, take the printer to a qualified technician, for trouble-shooting.

Battery problem MFC 7420


Tis a long way down my friend, I've never had to change one, on any brother printer, but I've never encondered them knowing not the time either. I suggest you take it to the repair agent, or get a manual but for what its worth this is what I know

I've seen the battery when I've had the scanner unit off the base printer, comes off after all covers are removed and all the cables that attach them are disconnected, then theres clips on the sides and two(four?) locking screws on back(front?) from memory. and thats all a task in itself.

Heres the best pic i can find of the left base of your printer engine displaying battery position, hope this helps.
Cheers
