The front of the fixing film starts to move
toward the front when the front of the tension
roller is raised.
As the fixing film moves toward the front,
the coverage of the friction roller by the fix-
ing film will become greater to increase the
rotation force of the friction roller; the condi-
tion will cause the tension wire to move
down the front of the tension roller.
As the front of the tension roller is
moved down, the tension of the balance
spring will increase, and the tension roller
will stop where the tension of the tension
wire and the tension of the balance spring
become balanced.

c. Measures for 'E007'
Use fixing film displacement correction
mode if 'E007' is indicated as follows:
1) Tur off the power switch, and leave the
copier alone for about 10 min.
* The temperature of the fixing heater
will drop below 100°C.
2) Turn on the power switch.
* The copier indicates 'C' on the control
panel, and the fixing assembly
becomes activated moving the fixing
film (about 3 min).
The copier indicates 'C' on the contro}
panel while It executes film displace-
ment correction mode; advise the user
that the indication does not refer to an
error.
If 'E007' does not disappear after exe-
cuting the above fixing film displacement
correction mode, see the instructions under
"Correcting the Displacement of the Fixing
Film" in the Service Handbook (p.2-14).
