Usage of Xaar 126 Print Head
1¡ ¢
Flush liquid out of the print head
For print head protecting, lots of liquid is injected into the print head before it is used. The liquid must be
flushed out for the first time using. Before fixing the print head on the print head frame, operate as follows:
joint a filter on the In-tube of the print head, and then joint an injector--which fills with flush solution--on the
filter. Inject 30 ml flush solution into the print head to eject the liquid inside. Then fill full the print head with
flush solution for complete dissolving within 5-10 minutes. Finally, flush the print head with about 30ml
flush solution to eliminate the liquid completely. If you find the printing line is not linear, flush the print head
again.
Make sure to operate on a stable and clean platform.
Steps:
¢ Ù Suck some 20 ml flush solution into the injector.
¢ Ú
(some 15 ml)
¢ Û Plug up the inlet of print head and let solution flow out from the nozzles.
¢ Ü keep the print head stillness for some 10 minutes. And repeat the action of ¢ Ù

Extrude air from the print head
After fixing the print head on the print head frame (be careful of the in tube and out tube). Remove the
Cap from the Out tube; positive-pressure clean to make ink flow out from exhaust tube . During the process
air is extruded completely from the print head.
3¡ ¢
Wet the print head surface
After extruding air from the print head, cover the Cap on the Out tube. Positive-pressure clean again
until ink streams out from the nozzles, then wipe the print head surface with a clean stick (without flush
solution) to form a protecting coat on the print head surface.
Notes: When ink on the print head surface streams into nozzles completely and the surface is dry,
never wipe on the print head surface, because that will orient air into the nozzle and shape bubbles in
Inject flush solution into the inlet of the print head and let it flow out from the outlet.
Operate on a clean and convenient platform.
Never touch the surface and socket of the print head with your fingers.
The injector should be filtrated with a filter.
Extend the outlet of the print head with an ink tube and ensure cleaning solution won't
inpour into the socket.
Never touch the print head surface with other objects.
Dispose the inlet and outlet carefully.
The force to inject cleaning solution can't exceed 0.3 kg.
