2.14 TAPE EJECTION
If a loaded cassette tape cannot be ejected due to a failure
in the electrical circuitry, take the cassette tape out using the
following procedure.
However, this method consists of a forced driving of the load-
ing motor. Therefore, the following description assumes that
there is no trouble in the mechanism operations.
1. Unplug the power plug from the power outlet, then re-
move the top cover.
2. Apply 3 V DC to the electrodes (Red wire: + pole. Brown
wire: - pole) on the upper part of the loading motor to per-
form the unloading operation so that the pole base as-
semblies are returned on the inner side of the tape. At
this time, the exit guide arm assembly should return to-
ward the drum assembly and the mechanism should en-
ter the C-IN mode.
As the tape is left without winding, be careful not to dam-
age the tape or leave grease on it.
3. If the tape is slack, wind it up by turning the shaft on the
topside of the capstan motor in the direction of the arrow
using a pointed tool (chip IC replacement jig).
This operation may be difficult because the shaft is lo-
cated below the housing motor of the cassette housing
assembly. Be careful not to damage parts during it.
4. After confirming that the tape is fully wound up, take out
the cassette tape by turning the gear of the cassette hous-
ing assembly in the direction of the arrow.
Note :
• After ejecting the tape, check that grease or similar for-
eign material is not attached to the wound tape. Also
perform similar checking for the mechanism assembly,
particularly the tape transport system.
