Caution1: After reinstalling fixing temperature
sensor 2, make sure that the sensor
touches the fixing upper roller.
Caution2: Make sure the sensor wires do not
touch the fixing upper roller.

sensor 1, adjust its position using the
positioning jig (4024-2990-01) and
secure it with screws. Be sure to apply
screw lock agent to the screws. This
adjustment should be made in a
pressured state.

Reinstallation procedure
(1) Secure fixing temperature sensor 2 to the fixing

touches the fixing upper roller. If they do not
touch each other, be sure to bring the sensor in
contact with the roller.
(3) Set a fixing temperature sensor positioning jig
between fixing temperature sensor 1 and fixing
upper roller, and secure fixing temperature sen-
sor 1 with two screws so that the distance
between the sensor and roller is equal to the
thickness of the jig.
The fixing temperature
sensor 2 must contact
the fixing upper roller.
