27

After placing the document, align the document guides with both 
edges of the document.

• If the carrier sheet or passport is not loaded properly, you may 

get a document jam or not get a scan image as intended.

• When scanning passports, clear the [Detect by Ultrasonic] 

check box in the [Feeding] tab on the scanner driver settings 
screen. 

• Depending on the condition of the carrier sheet or passport, the 

image may not be scanned completely or the scanner's image 
correction may not function properly. If this is the case, set 
[Page Size] to a larger paper size (A4, for example) on the 
scanner driver settings screen, and then scan again. 

• If the size of the passport differs greatly from the size of the 

carrier sheet, a document jam may occur or the scanner's 
image correction may not function properly.

• When scanning passports, set [Dots per inch] to 300 dpi or less 

on the scanner driver settings screen.

• The maximum thickness that can be scanned is 4 mm with the 

passport inserted inside the carrier sheet. If the thickness 
exceeds 4 mm, the scanner may break down due to problems 
such as paper jam.

• Documents other than passports should not be inserted into the 

carrier sheet and scanned. This may cause the scanner to 
break down.

• Carrier sheet is a consumable item. Replace it with a new one 

when necessary, if there are clear damages or smudges.

When scanning cards, set the feed selection lever to Bypass mode 
and then place one card at a time horizontally.
