More laser discovery

As I stood in my little workshop, waiting for glue to set on the fake Crocs from which the puppy removed significant portions, I noticed the laser portion of my printer dissection. I assumed it would need to be broken open, but now picked it up and saw it had four little plastic tabs – piece of cake!

And very cool! The laser is at the arrow on the right. The hexagonal disk has mirrored edges, and is attached to a motor. The bizarrely-shaped plastic lens is obviously very carefully designed to very precisely deliver incredibly tiny dots at incredibly high speed. The arrow on the left points to a tiny mirror whose purpose remains a mystery to me. Amazing technology.


The plastic bits on the right represent a slightly less amazing technology. I was unable to plug in a Schuko plug to an adaptor (maybe the very one labelled C in this post from 2012). I thought I’d take it apart, which it turns out involved breaking it, but the stuck safety gate shown here dropped out. So I glued the broken parts back together, and voilà – another silly little project done.
