Canon DR-G1130 Benutzerhandbuch

• If the scanner does not operate because of a system error, 

turn the scanner OFF and wait at least 10 seconds before 
turning it back ON. If errors continue to occur, reboot the 
scanner and computer.

• When scanning with configurations that use a large amount of 

the computer’s memory, scanning will be performed properly 
for the first scan. However, if a second scan is performed with 
the same configurations, an error may occur due to insufficient 
memory and scanning may not be possible. In such cases, 
restart the application you are using and change the 
configurations before scanning again.

■ Slow Scanning Speed

If the scanning speed is slow, first confirm the following:
Scanning may be slow if the USB interface does not 
support Hi-Speed USB 2.0.
✔ Does the PC’s USB interface support only Full-Speed 

USB 1.1? 

✔ Is the USB cable you are using the one that was 

supplied with the scanner (Hi-Speed USB 2.0 
compliant)? 

✔ Is a USB 1.1-compliant device connected to the USB 

hub at the same time?

If this does not solve the problem, consider the following 
possible causes:

Cause

Other applications are running in the 
background on your PC.

Solution

Quit all other applications that are running.

Cause

Resident applications, such as anti-virus 
software, are draining memory resources.

Solution

Quit all resident applications.

Cause

Temporary files cannot be created in the 
TEMP folder, as there is not enough free 
space on the hard disk.

Solution

Delete unnecessary files on the hard disk to 
increase free space.

■ Documents Do Not Feed Properly

If a document does not feed properly, first confirm the 
following:
✔ Are pages sticking together because of static electricity 

or another cause?

✔ Are you attempting to scan a document with size, paper 

thickness or quality that is not supported by the 
scanner? 

✔ Are the feed rollers dirty?

✔ Are the feed rollers worn out?

• Double feeding occurs when document pages stick together, 

and incompatible paper thickness or quality can cause paper 
jams. Check your documents carefully before loading.

• Replacement rollers can be purchased as consumables. If 

performance is not improved after cleaning the rollers, contact 
your local Canon dealer or service representative to purchase 
a Roller Replacement Kit, and replace the rollers (pickup, feed 
and retard rollers). 

If this does not solve the problem, consider the following 
possible problems and causes:

Problem Documents do not feed.
Cause

The Continuous Manual Feed Mode is 
enabled.

Solution

Set the Continuous Manual Feed Mode to 
[OFF] from the User Mode.
