× 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," in the User Manual.)

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.

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. 7.) 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. 12)

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. 9.
