6. Correcting the Displacement of the Fixing Film
a. Outline
As rotation continues, the fixing film tends to become displaced to the front or the rear. To correct such
displacement, the machine has a fixing film displacement correction mechanism.
The correction is by the fixing film sensor (PS2) for detecting the position of the fixing film motor (M5)
for correcting the position of the film.
Caution:
The lower roller is released when the front door is open. If the power is turned on in this condition,
the fixing film can become displaced or the fixing heater can become damaged.
Be sure to keep the roller locked when working with the front door open.
