I recently bought an Apple Magic Keyboard - 2nd hand - but key pressures are highly varied and often do not record a stroke. What could this be? Any idea how to fix it?

I think Calfox is right - just turn printer on, then unplug as carriage starts to move. Then it can be moved freely.

Also a 4 - 5 mm Allen key can be used to unhook the CSIC plate - place angled end of key behind carriage, & feel for the edge of the clip. Then pull forward on allen key, & up on the CSIC plate. Do both sides. Take care not to damage the encoder strip.

Will try scribe method next -

General - the reason you are reading this guide may well be that you blew you speakers after installing 'Boom' from the App Store.

All I can say is, don't install it a second time!

Others, be warned! If you use Boom, just use it at the lowest volume you can. Looks like they don't replace speakers.

Or better, don't install it at all.
