4. ADJUSTMENT
4-1. TAPE PATH ADJUSTMENT
The "Tape path" refers to the route of the tape from the supply
reel disk to the take-up reel disc via the video heads.
Each component part of the tape transport system particularly the
surface of parts which make direct contact with the tape must
always be kept clean, free of dust, oil, scratches and so forth.
The tape path system is factory preadjusted, when parts of the
tape transport system are replaced, be sure to make the required
adjustments as precisely as possible in order to ensure stable tape
transport.
