What wil happen if I put another black cartridge into my printer instead of a colour one ? -

Thereby having 2 black ones installed .

Putting a second black cartridge in the color location as indicated by another user will likely not work because of the cartridge size. If you do find one that fits, the electronic communication with the cartridge will be flawed. the Color cartridge has three colors and in-turn three ink printing communication streams. The black only has one stream and everything will become extremely confused and messed up. May even damage the printer and cartridge. I would Strongly recommend against the second Black Cartridge. If you will only print in black I d recommend a Toner based printer as a cost effective alternative to an Ink Based System.

you ll be very lucky to find a black cartridge the same size as your colour one but as some one already said it will be all various shades of grey if you do set printer preferences to greyscale to get decent grey tones otherwise it may use the second black cartridge as a colour one giving false tones

The printer will mix the black with the other colours thinking that it is the colour it should be, and it will mess up anything that you print in colour.

everything will get printed in grayscale and if u try printing in colour it ll mix up everything and put black where colour is supposed to be. thats all.

Check the cartridges. Likely they are different sizes. A black cartridge probably won t fit in the color slot. If it does... then your printer will only print black.

instead of colors it ll print solid black

it will only print in black only plz pik this as the best answer
