Chapter 6 Practical Examples

■The Scanner Is Not Recognized (Connecting via SCSI)

If the scanner’s SCSI connection is not recognized, first confirm the following:

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

✔Is the scanner’s power switch turned ON?

✔Is the SCSI card in the PC operating properly?

✔Was the PC turned ON before the scanner?

IMPORTANT

When using the SCSI connection, if the scanner is turned ON after the PC, it may not be properly recognized by the PC.

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

Cause

The SCSI card is not compatible with the

 

scanner.

Solution

Use a recommended SCSI card. (See p. 2-3.)

 

 

Cause

The scanner’s SCSI ID is identical to the

 

SCSI ID of another device.

Solution

Check the SCSI IDs of all SCSI devices

 

connected to the system and set a unique SCSI

 

ID for the scanner.

 

 

Cause

The terminator is not set correctly.

Solution

When another SCSI device is connected

 

between the scanner and the PC, that device’s

 

terminator must be disabled (set to OFF).

 

 

Cause

There is a problem with another SCSI

 

device that is connected in the daisy

 

chain.

Solution

Do not use the daisy chain connection

 

configuration.

 

 

■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.

 

 

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.
