<Adjustment procedure>

 Service Manual “14.6.2 Pressure roller cover”
(2) Take off the entrance guide.
 Service Manual “14.6.5 Entrance guide cover”
(3) Loosen the adjustment screw on the bracket of each thermistor. Then insert the 0.70 mm-
thermistor gap confirmation jig at 2 points; the gap between the pressure roller center thermistor
and the pressure roller, and the gap between the pressure roller side thermistor and the pressure
roller. Insert it parallel to the thermistor surface. Then adjust the position of the bracket by moving
it up or down and then fix the adjustment screw.
Note:
Adjust the scale mark of the jig to the position shown below. If not, it makes the gap adjustment
incorrect.
(4) Confirm that the 0.50 mm-thermistor gap confirmation jig is inserted without touching, but the
0.90 mm-jig contacts the thermistor surface. If this condition is met, end the procedure because
no adjustment is needed. If it is not, repeat the procedure from step (3).
Note:
Adjust the scale mark of the jig to the position shown below. If not, it makes the gap adjustment
incorrect.
