PRECAUTIONS IN PART REPLACEMENT
When servicing the unit with power on, be careful of the section outlined in white.
This is the primary power circuit which is live.
When checking the solder side in the tape travel mode, make sure that the tape has been loaded and then turn over
the PWB with due care to the primary power circuit.
Make readjustment, if needed after replacement of part, with the mechanism and its PWB in position in the main
frame.
(1) Start and end sensors: Q701 and Q702
Insert the sensor’s projection deep into the upper hole of the holder. Referring to the PWB, fix the sensors tight
enough.
When replacing the mechanism on the PWB  care should be taken that  the sensors locate into the mechanism
holder.
(2) Photocoupler: IC901
Refer to the symbol on the PWB and the anode marking of the part.
(3) Cam switches A and B: D708 and D705.
Adjust the notch of the part to the white marker symbol on the PWB. The part  must be flat to the PWB.
(4) Take-up and supply sensors: D711 and D712.
Be careful not to confuse the setting direction of these parts in reference to the symbols on the PWB. The part
must be flat to the PWB.
