Foam on my Roland SC-545EX waste dumper destroyed

That is not ordinary foam. Haven’t you remembered that the ink that you are using is a solvent?

Solvent dissolves ordinary foams and plastic.

You are a tool lucky for your action because your printer headed still working after replacing the waste dumper foam.

Actually, you can just remove the foam without any replacement.

The foam was there just to prevent splashing of inks. As you can see the hole after you have removed the foam is going to the waste container. If the printer head fires the ink on the waste dumper, the ink fired directly move on the waste container.

By the way, if you really need to have foam on the waste dumper, a napkin that girls are using when they have a menstrual period can do the job as a replacement for your destroyed foam.

A menstrual napkin is composed of fibers and can absorb liquids and cannot be melted by solvent ink.

Just cut the napkin and remove all plastic materials that prevent the liquid to leak outside.

We don’t need that, what we need is the just the absorbing materials.

Cut the napkin in the size of the waste dumper holder.
