TROUBLESHOOTING
The following items illustrate common problems encountered in the initial installation of the
CCD Scanner.
Common Scanning Problems
A barcode will not read, no tone is heard or indicator does not flash.
Make sure that the barcode is not wider than the scanner opening. Remember, the width of
the code also includes quiet zones, equal to 10 times the width of a narrow bar, at each
end of the code.
Make sure the code is approximately centered in the scanner opening.
Make sure that the scanner will read that barcode type, and that type is enabled. See Page
2-10 of this manual.
Make sure that the code is of reasonable quality in that the printing is not smeared an there
seems to be good contrast between the bars and spaces.
Keyboard Wedge Configuration.
Connectors will not fit the keyboard.
The scanner can be ordered with the two most popular connectors used on IBM PC and
PC compatible keyboards; the 5-pin DIN connector and the 6-Pin mini-DIN connector. If
these connectors do not match your keyboard, check Page 2-2 of this manual to make sure
that this scanner will function with your keyboard. Adapters may be necessary to interface
to your keyboard.
The scanner beeps and the indicator flashes, but no data appears on the screen.
Make sure that the scanner is configured as a keyboard wedge. Since this is the default
interface, scan the SET code on the top of any even page of Section 2. Scan the codes for
the keyboard type and language on page 2-2. Scan the End Code.
Type a few characters on the keyboard to test the connection. If characters do not appear
on the screen, check each cable connection as well as the connection to the scanner.
Only some of the characters that are in the barcode appear on the screen.
Slow down the speed at which the data is sent from the scanner. Page 2-3 in the next
section shows how to accomplish this.
