To Replace the Interface Cable:
1. Turn the power to the host system OFF.
2. Disconnect the document reader’s cable from the terminal or computer.
3. Locate the small hole on the front of the imager. This is the cable release.
4. Straighten one end of a paper clip.
5. Insert the end of the paper clip into the small hole and press in. This depresses the
retention tab, releasing the connector. Pull the connector out while maintaining
pressure on the paper clip, then remove the paper clip.
6. Replace with the new cable.
Insert the connector into the opening and press firmly. The connector is keyed to go
in only one way, and will click into place.
Troubleshooting
The document reader automatically performs self-tests whenever you turn it on. If your document reader is not functioning
properly, review the following Troubleshooting Guide to try to isolate the problem.
Is the power on? Is the white scanning illumination on when the imager’s button is pressed?
If the aimer isn’t illuminated, check that:
• The cable is connected properly.
• The host system power is on (if external power isn’t used).
• The trigger works.
Is the document reader having trouble reading your barcodes?
If the document reader isn’t reading barcodes well, check that the barcodes:
• Aren’t smeared, rough, scratched, or exhibiting voids.
• Aren’t coated with frost or water droplets on the surface.
• Are enabled in the document reader or in the decoder to which the document reader connects.
Is the barcode displayed but not entered?
The barcode is displayed on the host device correctly, but you still have to press a key to enter it (the Enter/Return key or the
Tab key, for example).
You need to program a suffix. Programming a suffix enables the document reader to output the barcode data plus the key you
need (such as “CR”) to enter the data into your application. Refer to "Prefix/Suffix Overview" on page 4-1 for further information.
Does the document reader read the barcode incorrectly?
If the document reader reads a barcode, but the data is not displayed correctly on the host screen:
• The document reader may not be programmed for the appropriate terminal interface.
For example, you scan “12345” and the host displays “@es%.”
Reprogram the document reader with the correct Plug and Play or Terminal selection barcode. See Chapter 1 and Chapter 2 .
• The document reader may not be programmed to output your barcode data properly.
For example, you scan “12345” and the host displays “A12345B.”
Reprogram the document reader with the proper symbology selections. See Chapter 6 .
The document reader won’t read your barcode at all.
1.
Scan the sample barcodes in the back of this manual. If the document reader reads the sample barcodes, check that your
barcode is readable.
Verify that your barcode symbology is enabled (see Chapter 6 ).
2. If the document reader still can’t read the sample barcodes, scan "All Symbologies" on page 6-1.
