The setup country code for South Africa should be xx24 (which is changed in Maintenance 74). It's possible that you cannot change to this code, as region specific machines not always can change to codes out of their regions (i.e. Pan Nordic, Benelux, East Europe etc).

SOURCE: brother MFC 9420 says:reinstall tray#1, never goes to ready.

Here is a solution I found posted by Razor. (It turns out my engine controller board is bad.) Good luck with yours.

On your control panel, press "menu/set" "7" then "2". if your page count shows 288,888, you have a bad engine controller board. anything other than that count, most likely is a damaged paper cassette. there is a tab on front left side that is probably worn or broke off.

SOURCE: how do i reset the life of the fuser on the mfc

Actually the Replace Fuser message on these specific models sometime fail to reset after you replace the part.

If this happens:
Press Menu 6,3 and then select option 4 (Fuser)
Press okay
Press Stop/Exit

If you haven't replaced the unit then you should try that first.

Additionally If you are an unhelpful troll, don't post your ad-homonym attack as a solution.

I have colored smears on left side of all my printed pages with my Brother MFC-9420 CN. What causes this?


It's not unusual for paper to hit the bottom of the print head, especially if the paper is bent. This can cause smearing. If you have pets, you can check for pet fur in the printer, or other foreign material inside that can also cause smearing.

I have a MFC-9420 CN that is giving me an "unable to print message" after I cleared a paper jam. I have turned it off and on several times, as that is the only help the user guide gives. I've read...


To reset on this machine you press the 3 and 9 together and scroll thru the options to reset. Unable to print without an error code doesn't tell me where your error might be.
