Error Brother 4F 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, hopefully without the annoying cannot clean message. All I ask is please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on helping.

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.
Error 41 means there is a major problem with the printhead, usually requires a print head replacement. My advice is to take it to a Brother service centre while if it is under warranty. If it's out of warranty they are usually a throw away job, the heads cost as much as the printer. Sorry I know what it feels like, just have a go and see what you can do, clean the heads and so on. All the Best and good luck: Pineworks

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!)
