ページを印刷するThe pinch-roijler and capstan shaft may be cleaned in a similar manner.
To gain proper access to all these parts of the mechanism, remove any cassette from the
compartment and leave the lid raised.
Pressing the Play Key will engage the mechanics
and move all parts into view.
It will be found easier to clean the entire surface of the pinch-roller if the power source
is connected (batteries or mains) so that the roller and capstan shaft rotate.
It is suggested that a proprietary Cassette Head Cleaning Cassette be usedafter manually
cleaning the record/play head in order to restore the polish and remove surface film.

reproduction, poor recordings and incomplete erasure.
Failure to maintain
the pinch-roller and capstan shaft in a clean condition is likely to
cause the tape to entangle and spill out of the cassette.
Do not touch the tape head with any metallic or sharp-pointed object.
