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 tape and make sure excessive tape wrinkle does
not occur at the tape guides.
1) If tape wrinkle is observed at the guide roller S, T, turn the guide roller S, T until wrinkle disappears.
2) If the tape wrinkle is still observed at the tape guide, perform the tilt adjustment of the ACE head.
