Question about Brother MFC 420CN All-In-One InkJet Printer
My brother mfc 420CN keeps turning off and on, and I also get MN1 in the top right side of the lcd. What gives, and how do I fix it???? Thanks
I realise this is an old question but I recently had a similar issue with our MFC-5860CN not receiving faxes and displaying the "Mn1" code. As it turns out "Mn1" means the machine is set to manual receive and was therefore not automatically receiving faxes. You will need to locate the "Receive Mode" option in the menu and change it to "Fax Only" or "Fax / Tel". Unfortunately I dont know what could have caused the turning off and on that the OP mentioned. I'm a little late to the party but I hope this info can help someone else!

Sorry, havent found any hints within the service man for your printer although they have listed all kinds of errors given by the machine. Did you had a lighting strike the days before? It could be that there was some high voltage which had affected the micro electronics of the pcb (Its just a guess). If so, try to do firmware update from the brother homepage. If your are lucky machine will work again.
