B. Fusing loop control
• To prevent double transferred images and brush effects, a loop is formed in the paper
between the 2nd image transfer and fusing sections. The loop corrects variations
between the paper conveyance speed during the image transfer and the fusing speed.
• The fusing loop detect sensor detects the length of the loop formed in the paper between
the 2nd transfer section and the fusing roller. According to the length, the rotation speed
of the fusing roller is varied. Thus the length of the loop formed in the paper in the fusing
section is controlled.
