My Brother printer stopped printing anything; it says “unable to print 4f”

 

                       4F message indicates that the print head is dead, you may have to be compelled to replace it to create it work once more. Before you replace it, you will wish to undertake this, see if it'll take away the unable error message.

 

1. Access the interior maintenance mode by pressing the Menu/Set button,

2. Then press 2 8 6 4 among two seconds, this could place you within the maintenance mode menu.

3. Enter 80, Scroll down using the arrow down (round) key,  you will find an entry listed as purge count.

4. If range is over 6000, enter 2 7 8 3,  this may reset the purge count price.

  Then the printer can restart, hopefully while not the annoying error message.
