Are you missing colors or do some of the colors appear dull? Perform this test to check the print head nozzles. Your printer will put out a set of lines and colors, and you will use your computer interface to tell your printer which print looks the best. That allows the utility to determine and correct the problem. If the printer's diagnostic page prints gaps, you need to perform a nozzle check.

Note: Some color cartridges contain four or more colors per cartridge. If you tend to use more of one particular color, it is likely you will run out of that color before the others. If this happens, regardless of how much ink is in the other color chambers, it is time to replace the cartridge. Now there are printers that allow you to purchase individual color cartridges that save you money in the long run by preventing this waste.
