You should be able to choose disable cartridge check in the diagnostics menu and when the printer says ready, diagnostics mode, you can remove all the color toners just leaving the black in the printer and it should print ok. If you get blank pages, then move the black toner one of the color slots and then run the pq troubleshooting pages from the diagnostics menu to see if you get one page that has black on it. If you do not then the issue is a bad black toner also.
