42 Using the Scanner
Calibrating Paper Thickness
If documents do not feed properly (sheets double-feed or no sheets are fed),
you need to adjust the gap between the separation roller and the feeding roller
as follows.
IMPORTANT
•Make sure that the size, thickness, and weight of your document meets
the conditions of this scanner. See “Documents,” on page 36.
• Your unit has been carefully adjusted to meet most conditions. However,
the below adjustment may be needed depending on your environment
(humidity, temperature, etc.) and the documents you are scanning
(checks, etc.). Perform the adjustment only if necessary.
1 Hook your finger around the open lever and open the maintenance cover.
The separation roller and the feeding roller are exposed.
2 Pull out the document feed tray.
