Specifications

the damper(one way valve) is suitable for the ciss of HP, Canon, Lemark, etc.

if the temprature go up/down sharply,  the ink of cartridge might leak out from printer head 

    or flow back from ink cartridge to ink tank for normal ciss without damper , then it will cause the damage of printer head if empty ink.

our ciss with damper will advoid this problem!
