Cleaning the Print Head
Clean the print head if horizontal streaks are present in the printed nozzle check pattern. Cleaning unclogs the nozzles and restores the print head condition. Cleaning the print head consumes ink, so clean the print head only when necessary.
-
Make sure that the printer is powered on.
-
Press the Setup 
button, use the 
buttons to select Maintenance, and press the OK button.
-
Use the buttons to select Cleaning and then press the OK button.
The printer starts cleaning the print head.
Do not perform any other operations until the printer completes the cleaning of the print head. This takes about 1 minute.
-
Print a nozzle check pattern to determine if the print head is properly working.
If the problem isn't resolved after cleaning the print head twice, clean the print head deeply.
