Mimaki, Mutoh and Roland printers all use more or less the same dampers that fall into the following categories:
Small dampers with small mesh:
This damper was the first model that came to the market many years ago for Roland Versacamm, Roland Soljet, Mutoh Rockhopper and Mimaki JV4/JV3 printers. The small mesh often caused some problems as the ink pigment built up on the mesh during printer and caused starvation. This damper has a 2mm fitting that fits the older models of the Roland FJ/SC/SJ/SP series, Mimaki JV3/JV22/JV4, Mutoh RH II/Spitfire/Falcon/RJ8000. We recommend using the small dampers with large mesh instead as it will help prevent ink starvation during printing.
Small dampers with large mesh:
The small damper with small mesh was re-designed to solve the ink starvation problem into this small damper with large mesh. This damper also has a 2mm fitting that fits the older models of the Roland FJ/SC/SJ/SP series, Mimaki JV3/JV22/JV4, Mutoh RH II/Spitfire/Falcon/RJ8000.
Large dampers with 3mm fitting:
These large size filters were designed for the recent models of Roland Pro II/III, VP, XJ, XC series and Mimaki JV3 SP printers that require 3mm fittings for tubes. This damper improves the printer performance and prevents ink starvation in high speed mode.
Large dampers with 2mm fitting adapter:
These dampers were designed to fit older printer models that generally use small dampers. Changing from a small size damper to a large size damper helps improve the printer performance in high printing speed. Since the large size dampers originally come with 3mm fittings, an adapter was added to fit the older printer models using 2mm tubes. The large dampers with 2mm fitting adapters are compatible with most older printer models such as Roland Soljet / Versacamm, Mimaki JV3/JV22 and Mutoh Rockhopper II/RJ8000/ Spitfire ecosolvent printers.
If you are not sure whether your printer needs a 2mm fitting damper or a 3mm fitting damper, simply remove a damper and measure the size of the outer diameter of the connector. If your printer is equipped with large size original filters, it is most likely 3mm fitting dampers.
The Mutoh Valuejet uses a specific damper model which is different filters from those listed above.
The quality of the dampers is defined by the colour of the o-ring. Digiprint Supplies only supply dampers with blueor grey o-rings which are the most resistant to solvents.
