1.3 Print head cleaning

Take the following precautions when cleaning ink from around the nozzle.

catching the makeup in a beaker.
Cleaning range
(2) After cleaning, thoroughly wipe the print head with wiping paper and allow it to dry.
●Thoroughly dry the nozzle, charge electrode, deflection electrode, mounting base and fringe of the gutter.
Confirm that the parts are sufficiently dry before starting the next operation.
If operated while wet, the printer will not start normally.
●While the print head is wet, do not orient its end upward.
(3) Never immerse the print head in the makeup.
(4)When printing is frequently performed or the distance between the print material and the print head is short,
ink splashes may stain the end of the print head and the print head cover. If this condition is left unresolved, the
stained status will be made worse, resulting in a print error or emergency stop. If a print error or emergency
stop frequently occurs because of stain due to ink splashes, stop the operation in progress and clean the end of
the print head (around the nozzle, charge electrode, deflection electrode, mounting base and gutter) and the
print head cover. Do this in addition to the cleaning to be performed at the end of each day's work.
Air purging of the print head is effective against staining due to ink splashing.
See the Technical Manual "3.1 Print head air purge".
