PRECAUTIONS IN PART REPLACEMENT
When servicing the unit with power on, be careful to the section marked white all over.
This is the primary power circuit which is live.
When checking the soldering side in the tape travel mode, make sure first 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: D804 and D803
Insert the sensor's projection deep into the upper hole of the holder (LHLDZ1962AJ00). Referring to the PWB, fix the
sensors tight enough.
(2) Photocoupler RH-FX0007GEZZ: IC901
Refer to the symbol on the PWB and the anode marking of the part.
(3) Cam switches A and B (RH-PX0253GEZZ): D807 and D806
Adjust the notch of the part to the white marker of the symbol on the PWB. Do not allow any looseness.
(4) Take-up and supply sensors (RH-PX0252GEZZ): D801 and D802
Be careful not to confuse the setting direction of the parts in reference to the symbols on the PWB. Do not allow any
looseness.
(5) Diode bridge (RH-DX0083GEZZ): D901
Adjust the + marking of the part to the symbol's cathode marking on the PWB.
