By selecting the Long Document mode and setting the [Page Size] on the scanner driver settings screen to Auto-detection, documents of up to 3,000mm (118.1") in length can be scanned. Note the following when using the Long Document mode.

• When scanning in the Long Document mode, if the document is placed on the scanner in a skewed position, it may hit the edges of the feeding area and be damaged. Be careful to place the document so that it is not skewed.
• When scanning with the Long Document mode, paper jam detection may react slowly, resulting in damage to the document. Be careful to avoid paper jams.
• When scanning long documents, scan the documents one at a time.
• When scanning large-sized documents with the Long Document mode, scanning may be slower. Errors also occur due to memory shortage, and scanning may be disabled.
