My printouts are missing color and/or black print. What should I do?

• If color or black is missing, the problem could be due to a software setting (the printer software or your application may have been set to print black only) or the printer's condition. See more information.
  
  Note: In the course of troubleshooting this problem, you may try cleaning the print head. When you are using the print head cleaning utility for Mac OS 8.6 to 9.x, you must click the Close button when you see the screen below.
