Checking and Cleaning the 
Print Head
If your printouts are unexpectedly light, colors are 
missing, or you see light or dark lines across the 
page, you may need to clean the print head. This 
clears the print head nozzles, which can become 
clogged if you do not use the product for a long time.
Tip:
We recommend that you turn on the product at least once a month 
to maintain good print quality.
Checking the print head
You can print a nozzle check pattern to see if any 
print head nozzles are clogged, or to check the results 
after cleaning the print head.
1. Load A4-size plain paper in the sheet feeder 
(& page 6).
2. Press the F [Setup/Utilities] button.
3. Use the l or r button to select Check Ink 
Nozzles, and then press the x Start button to 
print the nozzle check pattern.
4. Examine the nozzle check pattern you printed. 
Each staggered line should be solid, with no 
gaps, as shown.
■ If your printout looks okay, the print head 
does not need to be cleaned yet. Press the F 
[Setup/Utilities] button to return to the 
previous mode.
■ If you see any gaps, as shown below, clean 
the print head as described in the next 
section.
