SOURCE: printer keeps turning off,,,error message MN1 in lcd

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.

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!)

I have a brother mfc-420cn. I am getting a unable to clean messa


Do you mean "unable to clean"?If it this follow this instruction.
Unplug the printer from power cord.Press and hold the "menu" button, then plug the device.You'll see on the LCD screen a "machine error" code.If this code is 40,41 or 4F the print head is defective.If the error is 50 or 51 there is error in Purge unit and printer require service.If the error is 46 the waste ink tank is full.Follow this:Enter 80, then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If numberis over 6000, enter 2 7 8 3.This will reset the purge count value. Then restart the printer, hopefully without the annoying cannot clean message.

Brother mfc 420 cn


if you have an error 41 the machine wont print any more due to a short circuit in the print head.

plz check error message.

anyway, if you have received error 41 you need a new printhead or better (because its cheaper) a new mfc.

sorry!

Error message on my Brother MFC-420CN


press menu then start bk copy then fourtimes arrow-up button. Machine will switch to maintaenance mode. You may have to press start bk-copy. The machine will display an error code.

Error code starting with 4 is always a defective print head which needs replacing (except error 46: new waist ink tank needed).

In case it is another error code plz post here again.

Printer keeps turning off,,,error message MN1 in lcd


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!

Printer message: Unable to Print


5A means that the purge cam stopps abnormally when it is in use. This could be of a broken cam shaft. You have to replace the whole purge unit. This is a service job to do!
