I think all of you have replaced a printhead valve module by yourself, have you ever tried to fix it? No? Let’s try do it now.

Generally speaking, it’s the failing valves that leads to the valve module stops functioning, so we focus on the valves now.

There are two valves on the 399181 printhead valve module, which look identical, but in fact, they are not the same.

The first vale is VB-S112-1300, 24v 8w, the other valve is VB-S112-1403, 19v 4.5w. Please replace both valves at the same time, and then the module will work like new.

If you run across leaking issue, we have the compatible purple sealer too. For more info, please feel free to drop us an inquiry.
