4-3-4. Checking and adjusting the tension pole position
(1) Check
When winding of P5-90 tape is started, check whether the tension pole is in the
specified position against Si roller as shown or not.
If it is not in the specified position, remove the cassette and adjust the position
in the following procedure.
(2) Adjustment
1. Don’t set up any tape, and select the PB mode. (Refer to Item 4-5-1-(4).)
2. Slightly loosen the screw (a) (to such a strength as the T band holder B can
be moved).
3. If the tension pole is in the inner position than specified, dislocate the T band
holder B in the arrow (A) direction and if it is in the outer position, dislocate it
in the arrow (B) position. Then, tighten the screw (a). (For reference, dislocate
it 0.4 to 0.8 mm outer from the position specified above.) For the position
adjustment, it is convenient to use the position adjustment screwdriver
(JiGDRiVERMX7U2). (Set it in the hole (C).)
4. Check the position in the “(1) Check” procedure described above.
5. If it is not in the specified position, repeat the adjusting procedure 1 thru 3.
Note:
• Tightening torque of screw (a) 70 mN·m
• To check the position, be sure to run the tape.
• If the cassette compartment assembly is removed, it makes the work easier. (Refer
to Item 4-5-3.)

4-3-5. Checking the take-up torque for rewind playback (VS-REW)
(1) Remove the cassette compartment ass'y and set to the sensor OFF mode.
(2) Set the torque gauge (JiGTG0045) on the S reel disk, and check in the rewind playback (VS-REW) that the torque at the supply
side is within the specified range.
Standard of take-up torque in rewind playback (SP mode)
31
±
5 g·cm with ripples less than 5 g·cm.
(If the torque ripples appear, read the center value of torque between the ripples.)
4-3-6. Checking the back tension torque for rewind playback (VS-REW)
(1) Set the torque cassette (JiG8T-032) in position, and check in the rewind playback (VS-REW) mode that the torque at the tape
take-up side is within the specified range.
Standard of back tension torque in rewind playback (SP mode):
14
±
5 g·cm with ripples less than 5 g·cm
(If the torque ripples appear, read the center value of torque between the ripples.)
