4.After the nozzle check finishes printing, make sure each line is complete, without any gaps or missing dots:

If any dots are missing, as shown below, clean the print head as described in the next section.

Running the Head Cleaning Utility

If you need to clean the print head, follow these steps:

1.Press the Setup button to enter Setup Mode.

2.Press the green button next to the LCD screen until you see Head Cleaning displayed, then press the x Color button.

The CX6600 runs a head cleaning cycle, and you see the message “Head cleaning . . .” on the LCD screen.

Caution:

Never turn off the CX6600 while head cleaning is in progress, or you may damage the CX6600.

3.When the message “Head cleaning . . .” disappears, repeat the nozzle check (see page 31) to verify that the print head is clean.

If you don’t see any improvement after cleaning three or four times, turn off the CX6600 and wait overnight. This lets any dried ink soften. Then try cleaning the print head again the next day.
