Canon FY8-13EX-000, NP6218 service manual Fixing System

CHAPTER 6 FIXING SYSTEM

Displacement of the fixing film is physically corrected by the fixing film motor (M4). When it identifies displacement of the fixing film, the DC controller rotates the fixing

film motor to move the rear of the tension roller up and down, thereby moving the fixing film to the center to correct the displacement.

When the fixing film becomes displaced toward the rear, the tension roller is moved down to move the fixing film toward the front.

When the fixing film becomes displaced toward the front, on the other hand, the tension roller is moved up to move the fixing film toward the rear.

The fixing film is positioned properly by repeating these operations as necessary. If the film has become displaced so much that the mechanism fails to make adequate correction, ‘E007’ is indicated on the display. (See p. 10-110.)
