Precautions when pumping:
Do not forcefully pull the suction syringe to avoid damaging the nozzle;
After the air is exhausted, use a non-woven fabric dipped in distilled water and slowly wipe the nozzle slowly in one direction;
Pay attention to the force when pumping, vertical ink cartridge, slowly pull the syringe until the air in the syringe is sucked out, the extracted ink can not be used twice.
