Sorry the black slot is for black the color slot for color.
Black ink in color cartridge.
Now you can print black.
Remove the black ink cartridge.
No they are separate ink cartridges.
Select black print ink cartridge only and then click print to start the print job.
Turn the printer on and open up the door so you can get to the ink cartridges.
However some printers will allow you to print black only without the color tri cartridge installed.
Color cartridges use 3 different colors so no it will not work fine if you refill the color with black ink.

You state your cartridges are low.
You found the ink cartridges.
Supplying black ink on the tricolor cartridge immediately we damage the cartridge although there are ways to clean a cartridge when ink is put in the wrong color but in the case of a tri color cartridge when you fill it with black ink it has no solution.
To use even less black ink select the draft setting.
Sounds like they are empty.
Can i load two black ink catridges instead of one colour and one black ink catridge.
If you put black in then it will mix and probably look like shit.
As long as your printer also has a colour cartridge all the colours from the colour cartridge will print together to make.
I e one is black the other is color and both are needed and used for black text.
Plenty of b w laser printers are really cheap or you could look into if a continuous ink system is available for your lexmark model it s a series of tubes that connect ink bottle directly to the printhead instead of using a regular cartridge.
Alternately you may be able to coax a bit more life out of the color cartridge by getting a teacup and put about 1 of hot water in it.
Remove the color cartridge from the printer and put it nozzles down in the teacup.
That is only an estimate.
I take that back.
With most printers you are required to have ink in both the black and color.
