I get the following message "Print unable 4F" on my MFC-240c. The printer will not print or copy anything. I opened up the printer and I did not see anything unusual.

If still under warranty, I would call Brother for an RMA (return merchandise authorization) code and return the product. Why fiddle with it?

Error 4f mean the head drive voltage has dropped from the high to low level in an abnormally short period.This mean your printer need new print head.This will cost you just as a new printer, then think about new printer.

Print unable 4F

The most common cause is jammed or shredded paper. Check for tiny pieces of paper throughout. Hope this helps.

Access the internal maintenance mode by pressing the Menu/Set button, then press * 2 8 6 4 within 2 seconds. This should put you in the maintenance mode menu. Enter 80, then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If number is over 6000, enter 2 7 8 3.

This will reset the purge count value. Then the printer will restart, try this step by step.without missing any thing. thanks

Machine Error 50 either means that there is a loose object inside the machine (usually piece of paper), or that there is a mechanical error which would need you to have the machine sent to service.

Hi there
With some Brother printers you can try this.

Access the internal maintenance mode by pressing the Menu/Set button, then press * 2 8 6 4 within 2 seconds. This should put you in the maintenance mode menu. Enter 80, and then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If number is over 6000, enter 2 7 8 3.

This will reset the purge count value. Then the printer will restart, hopefully without the annoying cannot clean message.


Some times this happens because of using cheap compatible ink cartridges if this is the case change the ink cartridges.
