Controlling The Fixing Film Speed - Canon iR2200 Service Manual

2.3 Controlling the Fixing Film Speed

F06-202-02 shows the construction of the control system used for the fixing film speed;
the speed of rotation is controlled according to the changes in the output of the fixing film
sensor (PS26).
The following signal is used:
[1] Film rotation detection signal (FSAR_ROT_D): when the fixing film is rotating, alter-
nately '1' and '0'.
E007 (fixing film rotation error)
Indicates that the film rotation detection signal cannot be detected for 6 sec
or more when the reading of the main thermistor is 100°C or higher and, in
addition, the fixing motor is rotating.

Use it to adjust the rotation speed of the fixing film. Blurry images caused
by a fault in the fixing assembly can at times be corrected. (Blurry images
can occur 400-some millimeters of the trailing edge.) This mode may also
be used to adjust the reproduction ratio in feed direction.
