Hi our printer a brother mfc 665cw comes up with a error message 4F what does this mean and how do we fix this problem thanks


This is the Brother definition of error code 4F:
"The head drive voltage has dropped from the high to low level in an abnormally short period." or "The head drive voltage has not risen to the specified level within the specified period in the self-diagnosis"
Causes:
"Piezoelectric ceramic actuator defective (Cracks or rare short)"
or
"Main PCB defective"
No simple fix I'm afraid. You could contact a Brother repair agent but I expect they will want to charge you more than a new machine.
Getting hold of parts for a Brother machine as a private individual (i.e. you're not a trade professional) is almost impossible, and even if you can, parts are ridiculously expensive - again, 9 times out of 10 it costs more to repair than buy a new printer. I imagine this is to preserve Brother's service agents' business, and Brother's new machine sales. Sorry.

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.

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.

BROTHER MFC 5840cn MACHINE ERROR 4F


Downloaded service & repair manual for brother mfc 5840CW- my unit. Will follow repair directions to check the memory then replace required parts. Will be cheaper and faster than finding a repair shop and paying as much as the macine to fix it! Rip off prices for repairs today on units so they can get you to leave them and buy a new one. Then they fix the unit and sell it "refurbished"- not mine!
Your information on clearing memory, the ink cleaning codes and taping the cartridge from over cleaning was good. Thanks for the help!

Unable to clean message in brother dcp-115c aio


I saw on this site codes for another MFC to clear memory and reset the cleaning unit count code to zero. It worked on two of my brother mfc 820cw units. The third mfc 5840cn had unable to print error message 46- nothing at Brother. they want you to take everything to a repair shop.they don't help at all. Then the error went to 4F when I tried toclear the memory.As Iunderstand that message- it means I have to replace the printer head. Have no clue where or what it is. But I can read a manual as well as anyone and follow directions to fix it! Can't be worse than it is now! Good luck

Unable to print message on Printer LCD


The print head is defective and needs replacement.
BTW the sparepart costs quite a lot of money.
Its better to buy a new mfc!
