This is the only information I could find. Didn't your printer come with a black and color ink cartridge? If it did, all you need to do is take the ink cartridge out and write down the numbers written on the cartridge. The only ink cartridge I could positively confirm was the #24 color ink cartridge. The Lexmark website does not list any black ink cartridges for this model. This information was obtained from Officemax.com.
