6. Make sure paper is loaded in the printer and click Print nozzle check

pattern. Then click Next. The nozzle check pattern prints on your printer;

see page 23 for instructions on examining the nozzle check pattern.

7. If your print quality has improved, click Finish.

If your print quality has not improved, click Clean to run another cleaning

cycle. If you don’t notice any improvement after doing this three or four

times, check the print quality solutions on page 36.

Using the Printer Control Panel

Follow these steps to clean the print head:

1. Make sure the printer is turned on but not printing, and that the black and

color ink out lights are off. If either ink out light is on, you must replace

the ink cartridge before cleaning the print head.

2. Press the

cleaning button and hold it down for three seconds.

Cleaning takes about one minute, during which the printer makes some

noise and the power light flashes.

After the cleaning cycle is complete and the

power light stops flashing,

you need to confirm that the print head nozzles are clean and reset the

printer’s cleaning cycle. You can do this by printing a page. You can also

run the nozzle check utility; see the previous section.

Caution:

Never turn off the printer while the power light is flashing, unless the

printer hasn’t moved or made any noise for more than 5 minutes.

3. If your print quality has not improved, run another cleaning cycle. If you

don’t notice any improvement after doing this three or four times, check the

print quality solutions on page 36.
