CD player TOYOTA CAMRY 1999 Service Service Manual

TSB
The cassette tape head and capstan should be cleaned regularly to prevent poor sound
quality and/or cassettes from jamming.
The following conditions can easily be avoided by regularly cleaning the head with a tape
cleaner and only using good quality cassettes.
Since the tape head contacts the cassette tape, the tape head accumulates metal oxides
and dirt particles from the tape. In time, a layer of dirt forms on the tape head resulting in
poor transfer of information between the tape and the tape head. This typically causes a
reduction of the higher frequencies or a reduction of the brightness in sound quality.
Tape speed is controlled by the tape capstan and pinch rollers. If the capstan and pinch
rollers accumulate dirt, the tape may slip causing the music to play too fast or too slow.
Dirt can make the capstans sticky, causing the tape to become entangled in the cassette
mechanism. This can cause the cassette to become jammed in the player.
To reduce the occurrence of these conditions, the following approved cassette cleaners are
available through the non±parts system (Material Distribution Center).

CLEANING CASSETTE TAPE HEADSAND CAPSTANS ± AU001±97 (Revised) May 16, 1997
The following precautions should be taken to keep cassettes in good condition:
1. Remove the cassette from the player when the cassette is not in use.
2. Store the cassette in its case.
3. Store the cassette in a cool, dry area away from direct sunlight and magnetic
components such as speakers.
4. Avoid touching the tape itself. This could result in poor sound quality or sound drop out.
5. Keep the tape tightly wound as shown in
figure 2. Tape speed can be affected by
loosely wound tape.
6. Avoid inserting a cassette into the player if
the cassette label is loose or peeling as
shown in figure 3. This can cause a
cassette to become stuck in the player.
7. Use cassettes that are 90 minutes or
less in length. Cassettes over 90
minutes use extremely thin tape that is
subject to stretch, resulting in poor
sound quality.

B HOW TO USE THIS MANUAL
The ground points circuit diagram shows the connections from all major parts to the respective ground points. When
troubleshooting a faulty ground point, checking the system circuits which use a common ground may help you identify
the problem ground quickly. The relationship between ground points (
EA, IB and IC shown below) can also be
checked this way.
