Paper Feed Adjustment
Slide the paper feed adjustment lever to adjust paper feed when a paper feed
error occurs because of friction arising from a slippery document surface.
The paper feed adjustment lever can be adjusted to three positions.
The normal setting is the left (|) position. If the paper is slightly slippery, adjust it to
the center (||) position and to the right (|||) position if it is more slippery.
Affixing the Document Guide Labels
The scanner package contains function key labels and document guide labels.
These labels aid adjustment of the document guide.
Affix them on the document tray as shown in the figure below.
