Follow these steps to run the Head Cleaning utility (recommended method):
1.Make sure the printer is turned on but not printing, and both the B black and A color ink out lights are off. (If an ink out light is flashing, replace the ink cartridge instead.)
2.If you have an application running, access the printer settings dialog box as described on page 15 (Windows) or page 20 (Macintosh).
Or, with Windows, click Start, point to Settings, then select Printers.
3.Windows: Click the Utility tab.
Macintosh: Click the 
Utility button.
4.On the Utility menu, click the
Head Cleaning button.
5.Follow the instructions on the screen to clean the print head. Cleaning takes about 30 seconds,
during which the printer makes some noise and the Ppower light flashes.

Never turn off the printer while the Ppower light is flashing, unless the printer hasn’t moved or made noise for more than 5 minutes.
6.When the Ppower light stops flashing, run a nozzle check to confirm the print head nozzles are clean.
Make sure paper is loaded in the printer and click Print nozzle check pattern. Then click Next. The nozzle check pattern prints (see page 40 for details).
