Print head cleaning

1. Cleaning with the makeup ink should be restricted to the end of the print head. To
clean the end of the print head with the makeup ink, orient the end of the print head
downwards.
2. Never immerse the print head in the makeup ink.
3. After cleaning, thoroughly wipe off the print head with wiping paper and allow it to
dry.
It is necessary to wipe and dry the nozzle, charging electrode, deflecting
electrode, mounting base and fringe of the gutter.
While the print head is wet, do not orient its end upwards.
If you use the JP-K60, JP-F63, JP-K68 ink, you must allow the print head to dry
thoroughly before operating the printer because the ink does not dry easily.
