Brother MFC 210C printer unable to clean print head. How can I clean it manually? The inkjet cartridges are full but the printer does not print. Error message on display: unable to clean.

If your printer is like the 420CN Model, do not forget to disconnect the printer for resetting purposes and connect it again and it may clean properly and run fine. Good luck! hopes it work. It did for me. My printer is working fine and I like it. It does the work.

I have a brother mfc-420cn. I am getting a unable to clean messa

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.

Unable to clean error message can selext "all or Color after hitting ink button

This is very common on Brother MFCs - they self clean excessively and when they've done a set number of self-cleans, they refuse to print and give the error message you quote.

There is a work around - you can reset the self-clean counter - but this carries a small risk the waste ink from cleaning that is normally stored insde the machine in a tank/sponge MAY leak out. I've done the work around on my Brother MFC and, so far, no leakage so if I were you I'd take a punt.
Just Google "brother mfc unable to clean" and somewhere in the results will be how to reset the counter - it's all done from the keyboard so no tools required.

MFC-420CN error "Unable to Clean"

Unable to clean comes up as well when the ink absorber is full. It won't let you print or
clean until a fresh absorber is installed, as it could leak all over inside and out. A shop has to do the repair.

Canon DCP 115c

if your printer is a BROTHER which shows error 46 (unable to clean) it can be fixed:
you need a new waistink absorber which can be purchased from a brother service partner near your home (see brother homepage). After replacing there must a eeprom rest be done.

Buy a new waistinktank at a service partner who can be found at the brother homepage of your country. You need this sparepart to replace the old one. DONT CLEAN THE OLD ONE DUE TO SERIOUS DAMAGE OF THE WHOLE PRINTER.

Printer message: Unable to Print

5A means that the purge cam stopps abnormally when it is in use. This could be of a broken cam shaft. You have to replace the whole purge unit. This is a service job to do!
