If your printer will not print with either black or color ink on your document then could be a couple of possible issues that might need resolving. First of all has the printer given a warning about low ink or has the ink actually run out and need replacing? If so, then replace the ink cartridge as directed. It’s a myth that you don’t need black ink to print a color image or indeed that you can print black text without the printer requiring a color cartridge. The majority of printers require both the black and color ink cartridges to be recognized as having ink and will not operate if one of the colors is out of ink.
If you have just installed your ink cartridges correctly and there are no error messages relating to the cartridges, but the ink is still not showing when you print a document then the issue may be a blocked print head. The first step in checking this out is to go to the printer maintenance facility and run a test print to see if there is a trace of black printing at all. You can access this procedure in a couple of ways, either go to your printer icon at the bottom of your screen and select printer utility > maintenance > clean heads or go to file print and select printer utility > maintenance > clean heads. Performing a head cleaning procedure will force ink from the ink cartridge through the print head and clear any blockage that may be preventing the printing of the document. It’s important to remember that each time you perform a head cleaning procedure you print a test page to monitor the improvement of the print quality. The printer is clever enough to know that if you decide to perform another head cleaning procedure after printing a test page that the blockage was not cleared and will force a greater amount of ink through in a further attempt to clear the blockage. Although you may have no real option but to see it through, the downside of performing several head cleaning procedures is that it uses a lot of ink and will drain the ink cartridge quite fast.
