Here's a copy of the manual for your machine, free, from Janome:

Check p. 11 of the manual, 12 of the pdf... my guess is the bobbin winder is still stuck in towards the bobbin winding position. Click it on, then firmly click it back off and see if that cures it.
The sewing hook might also be jammed with thread and lint.
