9. If there is a narrower space, correct the erase head position by
loosing the erase heads’s tangency adjusting screws and moving
the head away from pinch roller.
10. Check to see if there is any tape curling at either tape guide
pin in the closed loop portion of the tape (i.e. between the
capstans).
11. If, during forward play, there is any tape curling at tape guide
pin (2), conduct the following: Unthread the tape from the
head assembly front. Remove both pinch rollers. Set the deck
in the play mode. Visually line-up the capstan and pinch roller
spindles,

If the pinch roller spindle is tilted to the left (right) side
from the capstan shaft, tape curling may occur at the upper
(lower) edge of the tape guide pin (2).

12. If not parallel, loosen the two screws mounting the reinforce-
ment plate then adjust using the correction jig (TEAC P/N
5736000100) as shown in Fig. 2-21.
Note that:
(1) Use the jig as near as possible to the pinch roller spindle.
(2) Do not touch the surface of spindle.
(3) Use no other tool for this adjustment!

13. If the tape curls at tape guide pin (3) in reverse play, correct in
the same way (steps 11 and 12).
14. After it is entirely corrected that there is no tape curting condi-
tion in the head assembly, fine-adjust each record and playback
height so that the brass-colored spacer of forward (reverse)
direction purpose head will show above (below) the moving
tape. (About as thick as a thin pencil line). Adjustment should
be done by equally turning three screws required correction
not to disturb tilt and azimuth regulation conducted before.
15. Finally, if necessary, make rough tangency adjustment of re-
spective head with tape running. After doing for erase head/s
recheck steps 8 and 9 (erase head/pinch roller space).
