7.2.2.3.3. AUDIO CONTROL HEAD HEIGHT ADJUSTMENT
The height of the Audio Control Head replacement part is preset at the factory.
Purpose:
To be sure the tape runs properly along the Control Head.
Symptom of Misadjustment:
If the control signal is not properly picked up, Servo Operation cannot be
achieved. A Blue screen will be seen in Playback.
This confirmation is required when the Audio Control Head is replaced.
1. Play back a T120 cassette tape and check that the lower edge of the tape runs
approximately 0.25 mm above the lower edge of the Audio Control Head.
2. If necessary, adjust Black Screws (A) and (B) clockwise to lower the tape or
counterclockwise to raise.
