Head cleaning

If you find that the printed data is unexpectedly faint or
dots in the printed data are missing, you may be able to
solve these problems by using the Head Cleaning
utility to clean the print head, which ensures that the
nozzles are delivering ink properly.
You can perform head cleaning from:
O Printer driver
O Printer's control panel
Note:
O The cleaning process consumes ink of all ink
cartridges at the same time. Even if you are using
only black inks, the head cleaning also consumes
color inks.
O You do not need to perform head cleaning unless
the printed data is blurred or the color of the
image is not good.
O After cleaning the print head, print a nozzle check
pattern to check if it is printed correctly.
O When the Ink Check light is flashing or on, you
cannot clean the print head. Replace the ink
cartridge with a new one first. (If the ink enough
remains for the head cleaning, you may perform
head cleaning using the printer's control panel.)
See "Replacing Ink Cartridges" on page 67
O When repeating head cleaning in a short time
period, the maintenance tank may be nearing the
end of its service life quickly due to minimal ink
evaporation in the tank.
