■Scanning Is Not Performed

If scanning does not start when it should, first confirm the following:

✔Are the scanner and PC correctly connected with the proper cable?

✔Is the scanner’s power switch turned ON?

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

Cause

The ISIS/TWAIN driver and Job

 

Registration Tool are not installed

 

correctly

Solution

Uninstall and then reinstall the ISIS/TWAIN

 

driver and Job Registration Tool.

 

 

Cause

Another application is using the driver for

 

this scanner.

Solution

Exit the application that is using the driver.

 

 

Cause

Memory is insufficient due to scan

 

conditions that require large amounts of

 

memory.

Solution

Exit the application currently in use, change

 

the scanning configurations after restarting the

 

application, and try scanning again.

 

 

IMPORTANT

It 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.

■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.

 

 

■The Two Sides of a Document are Not Scanned Simultaneously During Duplex Scanning

If the two sides of a document are scanned one side at a time during duplex scanning, confirm the following:

✔Is Single-Pass Duplex set to ON in the user mode settings?

✔Is Long Document mode set to OFF?

IMPORTANT

Single-pass duplex scanning is disabled when the amount of light emitted from the reverse-side scanning sensor is insufficient. (See p. 55.)
