8. De-Curling Roller
In general, toners of four different colors are fused to the fibers of paper to produce a color copy, and
wrapping the paper around the drum tends to curl the paper, possibly leading to jamming if left as is during
feeding or when picking up for the second side in two-sided copying mode.
The de-curling roller found between the fixing roller and the delivery roller is used to remove curling,
thereby limiting pick-up/feeding faults in two-sided copying.

9. Retracting the Separation Claw
The CLC1000 moves the separation claw away from the lower fixing roller by the drive of the separation
claw solenoid (SL15) during initial rotation and last rotation to limit damage to the lower fixing roller.
