Bill,

the cable connection between the ph and the main printer circuit board is weak or defective.

I have noticed, that this can only be fixed be replacing the whole ph.

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.

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-665 CW with "unable to print 4F" error


My MFC 665CW popped this same "Unable To Print 4F" error recently making the machine fully useless. Just an annoying triple beep and repeat error message to screen when trying to do anything at all with it. I wrote Brother about it. They said to check all through the machine (with a light) for any paper torn off inside, or unwanted foreign objects. This is a good step to do anyway to help maintain the printer. If that is not it, they said it would be a mechanical malfunction. I tried "resetting" by unplugging it for a while as they suggested to no avail. Also while I did find a bit of paper torn off down in my MFC 665 removing it had no effect.
