2–6COPYING PROCESSCOPYRIGHT © 1998 CANON INC. CANON NP6621 REV.0 FEB. 1998 PRINTED IN JAPAN (IMPRIME AU JAPON)H. Step 6 (separation)Figure 2-113The copier uses a curvature separation method,which separates copy paper from the photosensi-tive drum by the rigidity of the paper. However, thinpaper could at times fail to separate from the drumbecause of its low rigidity. To prevent such a prob-lem, a positive charge is applied to the separationstatic eliminator, thereby weakening the staticattraction for better separation.Reference:If the image on the photosensitive drum fails totransfer to copy paper because of a jam or thelike, the transfer charging roller could becomesoiled with toner.To prevent such a problem, the copier uses apositive transfer voltage when the scanner ismoving in reverse or during post rotation, therebyreturning the positively charged toner on thetransfer roller to the photosensitive drum.Figure 2-112Static eliminatorTransfer rollerTransfer rollerDownload service manual and resetter printer at http://printer1.blogspot.com
