9-2-6.    Replacement of print head 
If a problem of non-ejection of ink-jet droplets is not cleared even after cleaning the head nozzle, replace a print head 
with a new one. 
The replacement procedures vary from the color heads to the white heads. According to each of the replacement 
procedures, replace each print head with a new one separately. 
<TIPS> 
  Ink needs to be re-installed after replacing the print head. If the ink level is low, make a new ink pouch available for use.
