Checks the threading motor, the thread-end sensor, unthread-end
sensor and the cassette compartment.
1. Execute the THREADING.
2. Press and hold the [AUDIO|IN] (↑) key.
Confirm that the threading ring completes threading and the
message “THREAD END” appears on the monitor display.
3. Press and hold the [IN] (↓) key.
Confirm that the threading ring completes unthreading and
“UNTHREAD END” appears on the monitor display.
In the case of trouble :
If the threading motor does not rotate, or if the message
“THREAD END” does not appear even though threading is
complete, or if the message “UNTHREAD END” does not appear
on the monitor even though the unthreading is complete, check the
threading motor, the cassette compartment, the SV-212 board.
Check also the MS-64 board (the driver circuit and the threading
FG amplifier circuit) and the SE-512 board (the sensor).
