Aftershock of the fix
Was not a long term fix
Just over a week after we fixed our new printer we were welcomed by this picture. We had little doubt what happened: the isolator had broken.
This is how it looked after we removed the plastic which had covered everything and had disassembled the pusher.
And this is what really happened: the isolator had broken into half. Just as we suspected at the first glance. We already contacted the supplier to address the problem. In the meantime we are looking for some solution to be able to print.
