Troubleshooting

Common Problems and Solutions

This section provides recommended solutions to common problems. If you have a problem that is not solved by the following, contact your local authorized Canon dealer.

Problem 1 The scanner does not turn ON.

Solutions

(1)

The scanner remains OFF while the feed tray is

 

 

closed. When you open the feed tray, the scanner

 

 

turns ON automatically.

 

(2)

If the scanner is connected to the computer via a

 

 

USB hub, try removing the hub and connecting

 

 

directly to the computer.

Problem 2 The scanner is not recognized.

Solutions

(1)

Confirm that the scanner is properly connected to

 

 

the computer with a USB cable.

 

(2)

Confirm that the scanner is turned ON. See the

 

 

previous problem (1) if the scanner does not turn

 

 

ON.

 

(3)

The computer’s USB interface may not support the

 

 

scanner. The scanner cannot be guaranteed to

 

 

work with all USB interfaces.

 

(4)

Confirm that the supplied USB cable is used to

 

 

connect the scanner to the computer. The scanner

 

 

cannot be guaranteed to work with all available USB

 

 

cables.

 

(5)

When the Auto Start switch on the scanner is set to

 

 

ON, you can only scan with the built-in application,

 

 

CaptureOnTouch Lite. In this case, scanning from

 

 

applications on the computer is disabled.

 

(6)

If “?”, “!”, or “x” icons appear for the scanner in

 

 

Windows Device Manager, delete the scanner in

 

 

Device Manager and reinstall the scanner driver.

Problem 3 CaptureOnTouch Lite does not start.

Solutions

(1)

If the Auto Start switch on the scanner is set to OFF,

 

 

the built-in application, CaptureOnTouch Lite, does

 

 

not start. Close the feed tray to turn OFF the

 

 

scanner, and set the Auto Start switch to ON.

 

(2) CaptureOnTouch Lite does not start automatically in

 

 

Windows 2000. Open the [ONTOUCHLITE] drive

 

 

under [My Computer] in Windows Explorer, and

 

 

double-click (ONTOUCH.exe). Depending on

 

 

settings for your operating system,

 

 

CaptureOnTouch Lite may not start automatically in

 

 

Windows Vista and Windows XP. Perform the same

 

 

procedure as above to start CaptureOnTouch Lite in

 

 

this case.

 

(3)

If access to USB devices is blocked by security

 

 

software, you may not be able to use

 

 

CaptureOnTouch Lite.

Problem 4 The auto play screen appears when the scanner is

 

connected, but you cannot scan with

 

CaptureOnTouch.

Solutions

When the Auto Start switch on the scanner is set to ON,

 

you can only scan with the built-in application,

 

CaptureOnTouch Lite. Close the feed tray to turn OFF

 

the scanner, and set the Auto Start switch to OFF.
