Replace the rollers that you removed. (See “Installing and
Removing the Rollers,” on p.91.)
9
Carefully close the upper scanner.
10
Press the upper scanner down firmly on both sides to close it.
If you press the upper scanner down only on one side, the opposite side
will not be fully closed. Make sure that you hear it click into place.
If paper jams or double-feed (feeding of two or more document pages) occurs
frequently in spite of your having cleaned the rollers, a probable cause is roller
friction. If this happens, replace the rollers. Contact your service representative.
