I have a Eumig S910 take up spool not spinning. Seems like a clutch is not placing anough pressure on the gear that dtrives the spool. I found this video on YouTube which is essntially the same projector and they are replacing the worm gear, but the video doesn't explain if the worm gear is being replaced becasue of the issue I have listed above. https://youtu.be/8HGUY2mnSRA

Any tips on how to fix this at all, please?

Slack drive belt? Gummed up lubricant (try a shot of WD40 on the spool pivot)

Found this with a quick search (just copied your question and popped it onto Google)

Might be a close enough model.
