TG1 Height Adjustment
1)
Replay the tracking standard (XH2-1).
2)
Confirm that the waveform of the tape path is flat.
(Refer to Fig. 6-2-11, and 6-2-12.)
3)
Confirm to see that there are gaps between top edge of the tape
and the TG1 flange, and bottom edge and the TG1 flange.
(Refer to Fig. 6-2-13.)
If the top and/or the bottom edge of the tape contacts with TG1
flange, adjust the height of the TG1 so that there is gap between
the edge of the tape and the flange.
If the height of the TG1 is adjusted, check the entrance side of
the tape path waveform (refer to Fig. 6-2-11, and 6-2-12). If
there is any change in the entrance side of the tape path
waveform, re-adjust the entrance side (TG2). (Refer to “3-4.
TG2/TG4 Guide Fine Adjustment.)
