Canon imageFORMULA DR-C240 Office Document Scanner マニュアル

30

The length of documents that can be scanned with the scanner is 
normally 356 mm (14"), but you can scan documents up to 3,000 mm 
(118.1") long by setting the scanner to the Long Document mode.

By selecting the Long Document mode and setting the [Page Size] 
on the scanner driver settings screen to Auto-detection, documents 
of up to 3,000 mm (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, make sure to set the feed 

selection lever to Bypass mode, and 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.
