The loop control monitors the tension of the paper between the second-transfer roller and the fuser.

●

If the fuser rollers rotate more slowly than the secondary transfer rollers, the paper warp increases

and an image defect or paper crease occurs.

●

If the fuser rollers rotate faster than the secondary transfer rollers, the paper warp decreases and

the toner image fails to transfer to the paper correctly, causing color misregistration.

To prevent these problems, the loop sensors, which are located between the secondary transfer rollers

and the fuser rollers, detect whether the paper is sagging or is too taut. The DC controller adjusts the

speed of the fuser motor.
