Head, Pinch Roller and Capstan Cleaning

Playback sound quality can be greatly diminished if magnetic particles are allowed to accumulate on the recording/playback head or playback head. Be sure to clean the head periodically, normally 2 - 3 times a month, to maintain your deck’s original performance. Dirty heads may cause:

•Poor sound quality (lose of high frequency response)

•Decreased volume

•Skipping

•Incomplete erasure of previous recordings

If the pinch rollers and capstan are dirty, the tape may become tangled and damaged by wrapping around the pinch roller and capstan.

To prevent these problems, clean the heads, pinch rollers and capstans with a cotton swab dipped in cleaning fluid.

Demagnetizing

Residual magnetism builds up in the heads after the cassette deck has been used for an extended period of time. This buildup intro- duces noise and static into tapes and impairs high frequency response. To prevent this, demagnetize the heads with any com- mercially available head eraser once every 50 hours of use. Refer to the instruction manual of the head eraser for detailed instructions.
