2-2 Tape Transport System Adjustment
When parts are replaced, perform the required adjustments by referring to precedures for the tape transport
system. If there are any changes to the tape path, first run a T-120 (E-180) tape and make sure excessive tape wrin-
kle does not occur at the tape guides.
1. If tape wrinkle is observed at the S, T-guide rollers, turn the S, T-guide rollers until wrinkle disappears.
2. If the tape wrinkle is still observed at the tape guide, perform the tilt adjustment of the A/C head.
