Refill Instructions:

With a double derlin, from one unit, cartridge is fill, from the other unit cartridge is vacuumed. Thus, the old ink inside the vacuum unit is not mixed with the ink in refilling channels. So, different units are used to fill and

vacuum the cartridges in order to prevent old ink to go through the nozzles.


Derlin Machines
Derlin Machines are used for the purpose of refilling & vacuuming ink through the nozzles of the cartridge

Derlin Machines are not only used for refill machines but also for refilling/vacuuming by hand

Derlin Machines are more durable than the plastic refill & vacuum clips, because of their mecanism and raw material
