I want to know how the gap between the dampers and the printhead affect the printhead when they are separated for maintenance.

The damper is meant to break all air bubbles before the printhead, but it is possible to separate the two and leave space for air before re-connecting and printing again.

Is this small amount of air perfectly sound to let run through the printhead?

or should something light like a nozzle check be used after re-attaching?

Thanks for any input!

You're not letting air run through the printhead. Sounds like you're just talking about taking the dampers off the printhead nozzles.

Yeah you're totally right, but surely that same air between the the damper and printhead will have to exit via the printhead?

Not really sure what you mean, the air in the atmosphere in general?

 

[soundbox3]

Is air damaging in itself, or is it large pressure that damages the printhead?

Pressure would potentially damage the head but other than that unless you're going to do maintenance in a vaccum chamber, wearing a hazmat suit with oxygen supply then there's no way of escaping air in general

Ok, I think I have my answer thanks! I was just worried every time the printhead was disconnected from the dampers you'd end up trapping oxygen in between the two when putting them back together and this would have to be be expelled via the printhead.

But yeah, I think I shouldn't have anything to worry about?
