Loosen the adjustment screw [1] on the bracket of each thermistor. Then insert the 0.70 mm-
thermistor gap confirmation jig [2] 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 [3] by moving it up or down and then fix the adjustment screw.
(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).
Notes:
Adjust the scale mark [4] of the jig to the position shown below. If not, it makes the gap
adjustment incorrect.
