5-9 PINCH ROLLER PRESSURE
Specifications: Take-up: 500 g +20 g (16.9 oz. to 18.3
02.)
Supply: 250g +20 g (8.1 0z. to 9.5 oz.)
NOTE: Explanation in this section can be applied to both
left and right pinch rollers though only the right
one is illustrated.
1. Switch on POWER.
2. Place the deck in the play mode with no tape loaded. To
do this, refer to 5-2, steps 2 to 3.
3. Hook the spring scale to the pinch roller shaft.
4. Gently draw the pinch roller away from the capstan
shaft in a direction directly downwards until the capstan
shaft and the pinch roller are completely separated.
5. Gradually return the scale back until the pinch roller just
begins to rotate. The scale should then be reading approx.
500 g +20 g (16.9 oz. to 18.3 oz.) as the value of the
take-up side pinch roller (right) and approx. 250 g +20 g
(8.1 02. to 9.5 oz.) as the value of the supply side pinch
roller (left).
6. If the reading is out of the specified range, adjust the
tension of the pinch roller spring by bending the tab of
the pinch roller ass’y in the direction specified by the
arrow,

5-10 ADJUSTING HEIGHT OF PINCH
ROLLER GUIDES AND REC &
PLAY HEAD
1. Load the check base plate jig in the cassette holder.
. Attach the tip of the guide height check jig, resting the
check base plate jig, under the pinch roller guide as illus-
trated in Fig. 5-18, keeping a reasonable distance from
the capstan shaft in order not to scratch the shaft.
3. Using this jig, adjust the height of the guide by turning
the height adjusting screw. Be careful not to scratch the
tape driving surface of the guide. Make this adjustment
for both right and left pinch rollers.
4. Move the height check jig into proximity with the front
surface of the REC & PLAY head.
5. Carefully adjust the two height/azimuth screws until the
tip of the jig just fits under the tape guide of the head as
shown in Fig. 5-20.
6. At this time, adjustment should be done with the head
parallel to the slide base (as far as possible).
