This ink damper is suitable for Roland VS series printers. This is the original Roland part (number 1000012719 replacing 1000006526 which was discontinued).
This damper is white / transluscent and is recommended with all ESL inks. The black damper 1000013784 can be used as a alternative but Roland recommends using 1000012719 instead.
The main differences between the black and the white damper are the screens/nets in the dampers. These are even more tightly meshed in the black dampers.
The new LEC2-300 (UV ink) and XT-640 (sublimation ink) only use the black damper. For all other devices, running the Eco Sol Maxx inks, we highly recommend to use only the white damper 1000012719.
