Safety
Long-term Shutdown Guidelines
Please refer to the procedure of "auto flush" in the system maintenance. Long-term shutdown
requires that you drain out the ink from the printer and flush the ink system. This is necessary, as left
ink in the system will dry/solidify, causing problems when re-commissioning the printer.
Cleaning of Print Head
Most of ink used in printer is fast dry ink. This type of ink will come to dry and solidify immediately.
The "auto flush" function ensures that the nozzle and gutter will be cleaned when the printer is
starting up and shutting down.
Some ink sprayed out of the nozzle over time will accumulate on the charge deflection plate/nozzle
plate, causing the ink stream unable to spray out. It is necessary to clean the printhead manually.
(1) Take off nozzle cover, spray out make-up on nozzle plate, charge deflection, H.V. deflection
electrode and gutter, clean out printhead.
Do not clean this area with
cleanings.
Use wet paper with cleanings
to clean this area.
(2) Clean out the nozzle as the picture shows. Can not spray out make-up to other area.
(3) Dry the printhead using the rubber pipette bulb.
Ensure the nozzle, charge electrode, H.V. deflection electrode, gutter and surrounding area
are clean enough.
Do not force make-up to flow inside the nozzle.
