Using the Scanner 55
Chapter 2
Skew Detection Function
If long documents are skewed, then they may rub against the feed slot or the
edges of the feed path and be damaged. The scanner is equipped with a skew
detector function that detects when a skewed document hits the edge of the
feed slot. When a skewed document is detected, an error message is displayed
and scanning stops.
Note
Small documents are not detected by the sensor even if they are skewed.
Long Document Mode
Normally the scanner can scan documents up to 17.01" (432 mm) in length,
however if you change the settings to the Long Document mode it is possible
to scan documents up to a maximum of 118.1" (3,000 mm) in length. To use
the Long Document mode, change the scanner’s settings to the Long
Document mode in scanner properties. Set the paper size in the “ISIS/TWAIN
driver” to [Automatic Detection] to allow the scanner to detect documents up
to 118.1" (3,000 mm) long and to scan them. (See “Page Size,” on p. 68.)
IMPORTANT
Note the following points when using the Long Document mode.
• Documents may be scanned more slowly when the scanner is scanning with
automatic size detection in Long Document mode.
• When scanning in the Long Document mode, if the document is placed on
the scanner in a skewed position, it may rub against both sides of the feed
path and be damaged. Be careful to place the document so it is not skewed.
• When using the Long Document mode, the paper jam detection may react
slowly resulting in damage to the document. Be careful to avoid paper jams.
• Be sure to feed paper with the bypass mode when scanning in the Long
Document mode.
