Black ink is full but does not print.

I have a brother mfc210 and it seems that the black ink is clogged. I have changed the cartridge so I am sure that is not the problem. I have cleaned it several times. how do i change the print head or is there something else i should do?

Re: Black ink is full but does not print.

Did you make sure that the cart was placed well and the plastic hook secures the cart on top?

If you have used Easy Jet carts, you can stop here and give the whole machine a push to the bin!
Easy Jet carts and some other generic ink carts clogg the fine filter in front of the nozzles which cant be cleaned anymore.

The ph as a spare part is more costly than a new mfc 240c at a price discount!

But you can try this at least:
Use a new original brother carts (BK/C/Y/M). place carts and secure them! (this procedure will consume some ink!)
press menu then start bk copy then fourtimes arrow-up button. machine will be in maintenance mode. press 7 then 6 then 4 then start bk copy. machine will refresh ink in tubes and ph
and will do some cleaning cycles. when finished press 7 then 6 then 3 then start bk copy to run a special power purge.
When finished press 9 then 9. After machine is back in normal state run a test print.
If you still cant see any bk the ph cant be fixed anymore.

MFC-420CN refuses to recognize or use black ink

The print head is clogged.Try powerful cleaning:
Press menu, then start black copy, then four times arrow-up quickly after another.Machine will be in maintenance mode
(all lights will flash).
Press 7-6-4 and OK (or start-black-copy).
When finished press 7-6-3 then start black copy,
printer will do a power purge.
Leave maintenance mode by pressing 9-9.
If this not help better think about new printer, because cost of repairing this one is profitable.

Will not print text in documents, only headings.

When you go to print on your settings select print in black only. Did you buy Brother ink? Having old cartridges refilled or buying generic can pose a problem. I remember correctly brothers have a chip on the ink cartridge? I have gone through so many printers and its really not worth going any further, seems as though you have put sometime and effort in to this 100$ printer. Take 100$ & buy a kodak easy share all in one the ink is 15$ brand new.

Printer wont print black.already replaced with new ink but still wont print black

did you take the tape off the new cartridge and is the print head burned out for the black? if you installed the diagnostic's on it then run it and see what it says, otherwise expect the print head to be cooked, however it is possible to get a bad ink cartridge try tapping it on your finger and see if ink comes out if it does not then the ink cartridge is dried out or no good, about %15 of print cartridges are bad on just about any brand printer some more than others.

I Need to Print

Sadly in a word, 'No'.

Here is the exact answer from Brother:

Your Brother machine is designed to stop ALL printing operations
(printing from the pc, printing received faxes and printing copies or reports) when any of the ink cartridges are empty. This is to ensure the life of the print head and maintain premium print quality. If the unit were to continue printing, print jobs and cleaning cycles would suction air from the dry cartridge and damage the printhead. Even if you print in black only or change the print settings to MONO or GRAYSCALE to avoid printing in color, the programmed cleaning cycles would still suction the dry cartridge, because they are programmed to clean ALL the ink nozzles.

The only way to continue printing is to replace the empty ink cartridge or cartridges.

While memory is available, black and white faxes will continue to be received into memory. If a color fax is being received, the Brother machines HANDSHAKE will request the fax be sent as black and white fax.

All faxes received into memory will automatically print once the ink cartridge is replaced.

NOTE: Brother strongly recommends that customers do not use generic ink or refill their Brother ink cartridges. Using non-Brother supplies may affect the hardware performance, print quality and machine reliability since the ink formulation in genuine Brother ink cartridges prevent smearing and clogging of the print head. The Brother limited warranty does not apply to any problem that was caused by the use of unauthorized third party ink and/or cartridges.

Color not printing

If you are making copies or sending/receiving faxes Press Black Start or Color Start. Make sure your ink cartridges are fresh. Cartridges remain fresh for up to two years if kept in their original packaging, after that the ink may become clogged. Cartridge expiration dates are printed on the package.

Black Ink Cartridge

I don't the meaning of the word "clogged" but the better way to clean a printhead is to put hot water on a soft clothe and gently put the cartridge on and off a couple of time. You will see if the cartridge let ink leaking. Important do not scrap with your clothe under the cartridge.

Printer not printing

Unfortunately, like most multi cartridge ink jet printers when one ink is empty the printer will cease printing regardless of whether you just want to print in black and white and you have plenty of black ink left. I have heard of people tricking the printer into believing the cartridge is full by placing coloured tape etc in front of the ink sensing device but I am not sure how the Brother senses the ink levels as i have some aftermarket ink cartridges for mine which seem to be completely non-opaque (unlike the originals). The need to have colour cartridges in even if you only ever print with black ink is good news for Brother as the MFC-210c uses a large amount of ink during it's routine cleaning cycles (that you cant stop) and will empty all 3 cartridges in under 6 months without ever printer a single drop of colour ink. Sorry about all the bad news, at least your not alone......
