2.
Extrude air from the Print head
After fixing the head on the head frame (be cautious of the Inlet tube and Outlet tube). Remove the
Cap from the Outlet tube; positive-pressure clean to fill the head with ink till ink streams out from
nozzles. During the process air is extruded completely from the head.
3.
Moisturize Print head surface
After extruding air from the head, cover the Cap on the Outlet tube. Positive-pressure clean again
until ink streams out of the nozzles, then scrub the head surface with a dry clean stick to form a
protecting layer of ink on the head surface. The ink on the surface will stream into the nozzles
because of negative pressure.
Notes:
Never scrub the head surface when head surface is dry, for that will orient air into the nozzles
and shape bubbles in the tube lines and affect the printing quality.
4.
Test printing
Design some color blocks as 20x20cm with some image operating software, and set color luminance
as 100%, 50% and 10%. Print the color blocks under test mode and check the print result. If the print
result is normal which means no ink-break and no ink spots on the mediums, the printer can work
normally.
