My Brother printer (MFCJ4420DW) does not want to print. It says that "there is not enough ink to maintain print quality" and shows that the black and yellow ink cartridges are empty. I took them out and saw that they are not empty - each of them is about 20% full.
How can I tell Brother to continue printing with the remaining ink?
Alternatively, I would like to install only black ink cartridge and leave the yellow empty. How can I tell Brother to ignore the empty yellow cartridge and print with black only?
