Replacing a Cartridge When Print Quality Declines
Even if the 
ink out light isn’t flashing or on, you may need to replace an ink cartridge if it’s been installed in your printer for more than six months and print quality declines.
Follow these steps to replace old ink cartridges:
1.Print a nozzle check pattern to determine which cartridges need to be replaced:
Windows: 
printer icon on the Windows taskbar, and then click Nozzle Check.
Macintosh OS X: Open your Applications folder and
Macintosh 8.6 to 9.x: Open your application’s File menu and choose Print. Click the 
Utility button, then click the Nozzle Check button.
2.Follow the instructions on the screen to print the nozzle check pattern. Then examine the pattern for gaps in the lines. You need to replace only those cartridges whose colors show gaps in the line pattern, as shown below.
3. Make sure you have the correct replacement cartridges.
Note: You must have the new ink cartridges before you continue. Once you start the ink cartridge replacement procedure, you must complete all the steps in one session.
4.Lower the output tray and open the printer cover.
5.Press the 
ink button. The print head moves to the ink cartridge replacement position, and the 
power light begins to flash.
