Lexmark P915 Black Cartridge

I am setting up a Lexmark P915 for the first time, I mainly print
black text, so I want to know that if a substitute a black cartridge
for the photo cartridge in the left carrier, can I leave the right
carrier empty, not install the colour cartridge, so that I am using
the printer with the black cartridge only. In case I require colour or
to print a photo, I can insert the appropriate cartridges. The printer
comes with a photo + colour cartridge only. Thanks.
