The printer was not printing in black ink! Help?

My Brother MFC 210c printer is not printing magenta & have poor quality black ink. Please help!!?

• My printer allows me to print yellow and blue. Black is very limited. Magenta, I cannot print at all. I changed all my inks already, I just don't know why it's not printing. There is no error shown on the screen. I cleaned it multiple times and the results are the same when I test run it. The black quality is low, there's no appearance of Magenta, and the blue and yellow are good. Please help me if you can...This is driving me crazy! Thanks in advance! =)

• Answer:

  That model does not have print heads built into the ink cartridges. Your print heads need to be cleaned or replaced, if they are even replaceable on that model, which I believe they are not. If you have run the printhead cleaning technique from the printer driver and it does not fix it and you can not buy new print heads from Office Depot or some place like that, the printer is trash. Brother printers are not worth taking to a printer repair shop.
