× Slow Scanning Speed
The following problems might cause the scanning speed to be slow.
× Scanning Is Not Performed
Check the following if the scanner does not scan an image even though the 
scanning operation is performed:
Has the scanner been properly recognized by the computer?
Has the scanner driver been installed?
Has the application software been installed correctly? Has the application 
software been set up correctly?
Is there a problem in the PC system?
IMPORTANT
If documents are not scanned normally even if the scanner setup is OK, a 
probable cause is that the scanner driver or application software is not 
running correctly. Re-install the scanner driver or application software.
When system errors result in the scanner not functioning at all, turn OFF the 
scanner and wait at least ten seconds before turning it ON again. If the error 
continues to occur, restart the computer.
When scanning continues, make sure that the last document scanned was 
scanned correctly.
× Documents Do Not Feed Properly
The following are possible causes of a document failing to feed properly. Check 
each possible cause.
Problem
Solution
The scanner power is switched OFF.
Make sure that the scanner is switched ON. If the scanner is OFF, 
turn the scanner ON.
(See "Chapter 2 Setup - Connecting the Scanner to the Computer," 
on p. 15.)
Problem
Solution
The scanner does not support your USB interface.
This product is not guaranteed to operate with all types of USB 
interfaces. Contact your local authorized Canon dealer or service 
representative for more information.
Problem
Solution

Use the USB cable provided with the scanner.
Problem
Solution
The USB hub is not compatible with the scanner.
Remove the USB hub.
Problem
Solution
Other applications are running in the background on your PC.
Quit all other applications that are running.
Problem
Solution
Resident applications, such as anti-virus software, are draining 
memory resources.
Quit all resident applications.
Problem
Solution
Temporary files cannot be created in the TEMP folder, as there is 
not enough free space on the hard disk.
Delete unwanted files on the hard disk to increase free space on the 
hard disk.
Problem
Solution
The USB port you are using does not support Hi-Speed USB 2.0.
Scanning speeds are slower if your computer's standard USB 
interface is not compatible with Hi-Speed USB 2.0. (See p.11.) Use a 
computer that is equipped with USB that is compatible with 
Hi-Speed USB 2.0 as standard.
Problem
Solution
The USB cable does not support Hi-Speed USB 2.0.
Use the USB cable provided with the scanner.
Problem
Solution
The USB hub does not support Hi-Speed USB 2.0.
Remove the USB hub.
Problem
Solution
Static electricity, etc., is causing the pages of the document to 
stick together, and they cannot be separated correctly by the 
scanner.
Before you place your document, thoroughly fan the stack of pages. 
(See "Feeding in the Page Separation Mode," on p. 21.)
Problem
Solution
Attempting to scan a document of a size, thickness, or weight that 
the scanner cannot scan.
Check the size, thickness, and weight of the document. For 
information on the type of documents that you can use with the 
scanner, see "1. Documents," on p. 18.
