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>

Do not confuse the color side print head with the white side print head.
Check the case color (red for the color side, white for the white side) and replace the case.

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.
