(S/N 007*****~)
REASON
Tape error appears on the display for the following reasons.
1.  The gap between play arm and solenoid is insufficient.
When a unit having this problem is encountered trim the play arm material (approx
0.2 to 0.3mm).
Please refer to the drawing on the following page for the area to trim.
2.  Voltage supply instability to tape the mechanism at power up.
This can be solved by changing the surface mount resistor RT1 value from 82R to
560R and replace the resistor R923 (33R) with a zener diode (VHEDZ3R9BSB-1).
Please refer to the drawing on the following page for component locations.
ACTION
Please use the part number below for models with serial numbers after that listed
above.  The old and new parts are not interchangeable.
