Head, Pinch Roller and Capstan Cleaning
Playback sound quality can be greatly diminished if magnetic par-
ticles are allowed to accumulate on the recording or playback
heads. Be sure to clean the heads periodically, normally 2—3
times a month, to maintain your deck’s original performance.
Dirty heads will cause:
e Poor sound quality (loss of high frequency response)
e Decreased volume
e Skipping
e 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 and the other
metal parts in the area (like the capstan shafts) once every 50
hours of use. Keep the deck power off while using the demag-
netizer. Also place tapes far away from the work area.
