the clogs can no longer be removed.

If you will use the margin of media on which a check

after head cleaning, use the ubutton to rewind the
media until the Print Start Position reaches the position

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 there may be color differences in the
printouts 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).
Note:
If colors are faint or missing even after head cleaning,
clean around the print head.
