• Scanning multiple page documents:
Basically the same as feeding a single page document. The main difference is the function of the
ADF pad to prevent multi-page feeding.
The ADF pad touches the ADF roller. The friction caused when two document pages are pulled
in along with the rotation of the ADF roller are classified into three categories-one is between the
lower page and the ADF roller, another is between the upper page and ADF pad, and the third is
between the document pages. The document page is fed at the position with the least coefficient
of friction of these three.
As the ADF roller surface and the ADF pad are made of rubber, the position with the least coeffi-
cient of friction is between the document pages. Therefore, the two pages glide on each other,
only the lower page is fed along with the rotation of the ADF roller, and the upper document page
stays at the set position.
However, normal feeding is not performed when the friction between the pages is excessive.
In this case, document jams may occur or multiple pages may be fed together.
