Maintenance and Troubleshooting
Does the 3400 read your bar code incorrectly?
If the 3400 reads a bar code ( one beep for a good read ), but
the bar code is not displayed correctly on the host screen:
➊ The 3400 may not be programmed for the appropriate
terminal interface.
Example: You scan “12345” and the host displays “@es%.”
Reprogram the 3400 with the correct “Plug and Play”
or Terminal Selection bar code ( see Section 2.2, 2.3 ).
➋ The 3400 may not be programmed to output your bar
code properly.
Example: You scan “12345” and the host displays
“A12345B.”
Reprogram the 3400 with the proper Symbology
selections ( see Sections 3.5 and 3.6 ).
The 3400 won’t read your bar code at all?
If the 3400 will not read your bar code:
➊ Try scanning the Sample Bar Codes ( found inside the
back cover
).
If the 3400 reads
the Sample Bar Codes, check that your
bar code is readable. (
See “Is the 3400 having trouble
reading your bar codes” on the previous page.
)
If the 3400 does not read the Sample Bar Codes either,
continue to #2, below...
➋ If the 3400 won’t read the Sample Bar Codes either:
Verify that the bar code symbologies are enabled. ( See
Sections 3.5 and 3.6.
)
Verify that your bar code symbology is enabled. (
See
Sections 3.5 and 3.6.
)
Scan ENTER, DEFAULT, and EXIT on the first pages of
Sections 3.5 and 3.6 to enable most symbologies. (
MSI
and Plessey will have to be enabled individually in Section 3.6. )
