Threader hook on Janome 12000

Fern Knoll <fmk@...>

the White threader hook fell off on Janome 12000.  It does slip on, but don't want to break something else.  Any advice or experience?

That piece is made to snap on, but it takes a fair bit of pressure to make it snap. Try putting a spool directly under the treader, then pull it down and press the handle agains the top of the spool to snap on the threader. You should feel it snap. If it won't stay the white plastic holder may be cracked. See your dealer for assistance.
