printhead question??

[decaljunkie]

Is it possible to convert a dx4 water based print head to a solvent print head by changing the manifold to a eco solvent manifold?
has anyone done this before? thanks

To my knowledge, you can't use any water based printhead for solvent inks. Apparently Epson makes 2 versions and the main difference is the plastic used. From what I have been told, if you put a water based printhead in a solvent printer, it will work just long enough for the solvent to melt through the channels that are not made of solvent resistant plastic. Might be a few days or weeks depending on the circumstances, but eventually it will start to leak from the solvents.

incorrect.... tons of old Roland water based units have been converted to solvent.

Solvent resistant manifold suitable for Epson DX4 printheads. By replacing this manifold, you can turn a water based Epson DX4 printhead into a solvent resistant part suitable for Roland, Mutoh and Mimaki solvent printers. This manifold is sold together with the rubber ring necessary to adapt to a print head.

I stand corrected, I was thinking of the DX5 head, my bad.

I think you can do this on the DX5 print head also by attaching a solvent manifold.
But the manifold is bonded with sealant to the head on the DX5 unlike the DX4 which has replaceable seals.
I would not know how to or what sealant to use on the DX5.

DX 4 heads

In the past you could put a solvent manifold on a NEW aqueous DX4 head, flush it and you were good to go. Currently this is no longer true.

Why is that not true any more?
