Brother MFC 420CN shuts off and on automatically every minute

Brother printer MFC 420CN shuts off and on automatically every minute, makes scratching noise, and does not make copies, does not print, and does not fax. It shuts off even when you are in the middle of menu options.
I have tried disconnecting and connecting but the problem returns as soon as it is plugged into the power.

My brother printer MFC 420cn says it is not compatiable with windows 7


The MFC-420CN is part of the BH3 series which brother did not develop drivers or software for compatible with Windows 7.

This does not mean it is not compatible though.
What this means is that you can only use the built in drivers with windows 7.

When you plug is with a USB cable, it should install automatically for printing and scanning.

If you are using a network, you can go through the add a printer in "Devices and printers" but wont be able to scan.

If WIndows does not give you the option to select the MFC-420CN, then you will need to complete a windows update to have the driver.

Brother MFC 420CN error message DF

Did you had lightning strikes or a high tension the days before? DF means that the faxmodem which is placed on the pcb is in disorder. The pcb has to be changed (sparepart is more expensive then a new mfc!)
