Separation (Step 6) - Canon NP6330 Service Manual

H. Separation (step 6)
The copier takes advantage of the rigidity of copy paper to separate it from the drum
(curvature separation).
However, since thin copy paper has little rigidity, it can wrap around the drum without
separating. To prevent such a problem, a positive voltage is applied to the separation
static eliminator to weaken the static bonds between drum and copy paper, thereby
facilitating separation.
Copy paper possesses high resistance once it has moved through the fixing
assembly, and shows curling. For this reason, separation faults could occur if the same
degree of separation corona charging was used for copying on both first and second
sides in automatic two-sided mode. To prevent separation faults, the output of corona
charges is made stronger when copying on the second side.
