Hi ,
While printing go to the printer settings nad check if any Black print option is clicked. Also check the color cartridge status.

did you chech if the clack cartridge is empty or not..?

There is an override sequence and it works well. Press the select button (checkmark) to indicate Main menu. Press right-arrow (RA) to select System Setup. Press Select , then RA to Print Quality, Hit select. RA to Replace supplies and hit Select. Now, RA to Override Out and Select. Confirm with Select again. Your 2600n will now run even with an empty toner cartridge.

if the test pages come out OK then the problem can not be the printer !!!!!!!
it must be from the application

Most likely you have no black cartridge installed or it is empty causing your printer to use the colour cartridge for black. But if your colour cartridge has 1 colour which is less full than the others it causes black to become greenish or sometimes reddish depending on which colour is less. A new cartridge or a black cartridge will solve the problem.

its ok I solved it! I didn't realise that all the photo cartridge does is gloss over the colour picture produced by the colour cartridge. I simply had to replace the colour cartridge which had run out, so now its all working perfectly!!

On some printers, probably including yours, the black ink will be taken from the reserves in your colour cartridge unless you specifically tell it to do a black and white print on each document, regardless of whether it's printing black exclusively. I wouldn't worry, the black ink in it's own cartridge can also be used for colour photos etc with no detrimental effects.

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......
