Scanner mirror removal/replacement?
Ok, so I've got a set of scanners where the X galvo mirro is glued on so it's not in line with the spinle (it leans backwards)
This means that as it moves up, it also moves slightly to the left, meaning all my images come out leaning. I can correct it to some point in software, but thats no good when using more than one projector!
What is the correct/best way to remove it and refix it?
They appear to be scaneco 15's

Hold the mirror gently, pull and apply a gentle side to side force in the direction of the slot. The glue should let go before the mirror breaks. Don't squeeze too tight with your fingers or it will snap before you even start to pull. Chances are that the slot is out of line, so check that before you glue it back in.
Good luck, Ian

As Ian said but with it kept horizontal, touch a fine tipped soldering iron on the galvo shaft to soften the epoxy (no more than a few seconds) and it should come out easy. The mirror may get a bit damaged but hopefully on the bit that doesn't matter...

Thanks for that. I think the slot is simply too big for the thickness of mirror so when it got glued in it went into the slot diagonally. Just need to make sure its flat against the front or back of the slot I think.
Is 2 part epoxy the best for glueing it back with?

As Doc suggested, the slot is indeed out of line. What is the best way of fixing this up? Simply with a thin screwdriver in the slot and bend, or something more elegant?Chances are that the slot is out of line, so check that before you glue it back in

I don't think that works.
In my experience this can be very bad for the scanners.

You might be screwed.
If it was mine, and it was a last resort; I'd use a luthiers file and very carefully remove some metal in the desired direction, and maybe make a tiny shim from a drinks can.
Maybe somebody has a less agricultural idea?

It's all sorted, once I'd cleaned the slot out properly, the mirror actually wanted to drop in straight, so there may have been some debris or something in there when first put together. Strange, because when you look at the slot, it definately looks wonky!

If I've said it once...I've said it a million times...there ain't nothing like a wonky slot!
