The label on the respective cartridge must be removed above. Then you see in the black cartridge small hole, which I have expanded with a tiny screw. In the colorful cartridge then 3 Löcherchen be seen. Top magenta, left and right Cayan yellow.
The set includes 5 10ml syringes, needles 5, the 4 x 100ml ink tank and refill included.
In the extended holes Now push the needle of the filled syringe is introduced and slowly emptied the syringe. The holes are sealed with tape and stuck the label again when the cartridges have been made fully.
Very easily.
The quality and the price of 400ml ink are quite excellent, so I no longer has to constantly think about whether this or that I now no prints or.
Full class !!!
