8-2-1. Tape Run Adjustment
Perform the tape run adjustment only when the S1 tape guide or T1 tape guide or T3
tape guide or other tape guide assemblies (S2 to S5, T2, T5) is replaced or when the
parts such as stationary head in the tape run system are replaced.
Notes
. When the tape run adjustment is going to be started after parts of the tape run
system are replaced, check first the tape running status and adjust its system using
a cassette tape BCT-40HD that is commercially available, to confirm that a tape
can run safe without damage.
If a tape that does not have the CTL signal recording yet, is used, there can be a
case that the tension regulator oscillates in the PLAY mode that makes the check
and adjustment works difficult. In such a case, use of a tape that has the CTL
signal recording, is recommended.
Upon completion of the above check and adjustment, start the tape run check and
fine adjustment using the alignment tape HR2-1A.
. In the following check and adjustment procedures, all procedures are premised on
the use of the alignment tape unless specific cassette tape is specified.
