1.Make sure the printer is turned on but not printing, and the red b error light is off. (If the red light is flashing or on, you may need to replace the ink cartridge; see page 25 for details.)
2.Do one of the following:
■Windows: 
printer icon on your taskbar (in the lower right corner of your screen). Select Head Cleaning.
■Macintosh OS 8.5.1 to 9.x: Open the File menu and choose Page Setup or Print. Click the 
Utility button, then click the 
Head Cleaning button.
■Macintosh OS X:
Head Cleaning button.
3.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 green P power light flashes.
Never turn off the printer while the P power light is flashing, unless the printer hasn’t moved or made noise for more than 5 minutes.
4.When the P power light stops flashing, run a nozzle check to confirm the print head nozzles are clean.
Make sure plain paper is loaded in the printer and click Print Nozzle Check Pattern. Then click Print. The nozzle check pattern prints (see the next section for details).
5.If the nozzle check pattern has no gaps or lines, click Finish.
If the pattern has white lines, click Clean to clean the print head again.
If you don’t see any improvement after cleaning three or four times, check the solutions beginning on page 38. You can also turn the printer off and wait
