Head Cleaning
Should the nozzle pattern contain faint or missing segments, you may be able to unclog the
nozzles by cleaning the print head as described below.
There is no need to clean the head if the print result does not contain faint areas or other
color problems.
You can also clean the head while printing is paused. Note, however, that hues in the
printout may change when printing is resumed.
Head Cleaning Level
Choose from three levels of head cleaning.
Select Execute (Light) first. If the pattern still contains faint or missing segments after
head cleaning has been performed once, try again using Execute (Medium) or Execute
(Heavy).
