CHAPTER 1 GENERAL DESCRIPTIONCOPYRIGHT © 1997 CANON INC. CANON NP6330 REV.0 MAY 1997 PRINTED IN JAPAN (IMPRIME AU JAPON) 1-27H. Separation (step 6)Figure 1-612The 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 withoutseparating. To prevent such a problem, a positive voltage is applied to the separationstatic eliminator to weaken the static bonds between drum and copy paper, therebyfacilitating separation.Copy paper possesses high resistance once it has moved through the fixingassembly, and shows curling. For this reason, separation faults could occur if the samedegree of separation corona charging was used for copying on both first and secondsides in automatic two-sided mode. To prevent separation faults, the output of coronacharges is made stronger when copying on the second side.Transfer corona unitStatic eliminator
