Chapter 4: Troubleshooting Tips

The PowerLook 3000 scanner was designed to provide a hassle-free installation and

operation. However, should you encounter problems with your scanner, correct

them by way of the troubleshooting tips given in this chapter.

For persistent problems with your computer, consult your dealer or approved service

personnel.

General Approach

In most cases, a problem does not call for the service of a qualified technician. The

solution may be very simple, such as correcting cabling connections and the like. The

solution of a problem normally lies at the source of the problem. Therefore, it is

important that you ascertain the cause of the failure or malfunction. Below is a

general troubleshooting approach.

1.

 

Check the connections and installation. Ensure that there are no loose

connections. Ensure that the settings on the scanner and/or the interface card

are correct.

2.

 

Check the error messages appearing on the screen. Does the message point to a

hardware problem or software problem?

 

If the problem is software-related, refer to the software reference manuals or

on-line help. Most software manuals include a troubleshooting chapter.

 

If the problem is hardware-related, verify that the cause is from your computer

or scanner or in some cases, your network. If it is due to your computer

malfunctioning, then consult your computer’s reference manuals or a computer

service technician.

Note: Macintosh and IBM computers and compatibles display error messages

that normally tell you the cause of the problem and in some cases tell you

what to check or do to solve the problem.

1.

 

If the error message points to a problem with your scanner system, run the

scanner self-test.

 

Turn the power of your scanner on. At power on, your scanner automatically

runs the scanner self-test which can detect most of the problems with your

scanner.

 

Observe the behavior of the LED indicators. Record all your observations.
