Using Ultrasonic Double Feed Detection
The double feed detection function that the scanner is equipped with
uses the penetration of ultrasonic waves to detect when two or more
documents are fed at the same time.
If false detections happen too often, disable the double feed detection
function.
NOTE
When Using the Accompanying Scanning Utility for CR-135i/CR-190i:
You can disable the double feed detection function to push the Function
Button. When the function is disabled, the light of the Function Button is
off.
Placing Documents
Note the following points when placing documents on the scanner.
• Place the front of the document toward you.
• Do not exceed the Load Limit Mark when placing documents in
the document tray. This may cause feeding errors or paper jams.
• A maximum of 250 documents can be loaded at one time.
• Move the stopper to the edge of the document in the document
tray in accordance with the document. Otherwise, this may
cause a paper eject error.
