This section describes the types of documents that can be used and 
how to place them.

DocumentThe CR-50/80 can feed a wide variety of document sizes. The ranges 
of height and length for a document are:
Height : 50 to 108 mm (2.0 to 4.3)
Length : 80 to 228 mm (3.1 to 9.0)...

34
NOTE
Note that mixing documents of different thickness may cause a 
malfunction during feeding.
Curled, wrinkled, or folded documents may cause an error. If this happens, 
straighten out the curls, or reduce the number of documents loaded.
Using Infrared Double Feed Detection
The double feed detection function that the scanner is equipped with

at the same time.
If false detections happen too often, disable the double feed...
