Appendix E — Troubleshooting
Do not look directly into laser aperture.
Laser light can be hazardous to your eyes.
The MS-610 scanner when used correctly should produce good reads. If
not, table A-6 lists some of the more common problems associated with set-
ting up and using the scanner. If you are unable to locate or correct the
problem, call your Microscan representative.

WARNING
Solution
Check cable connections and wiring.
(See "Attach Cabling" on page 1-6.)
Verify that a <D> serial command (with
an upper case D) is being entered.
Reset scanner to default and/or match
host settings with scanner's.
Check baud rates and parity and change
to match the host's settings.
Check label configuration settings to be
certain that they match the label type
being scanned. If label type is in doubt,
enable Autodiscriminate All Codes (<P>
command).
Ensure that fixed length and check
sums, if enabled, are set correctly.
See range data in Step 2, "Verify Read
Range and Scan Width" on page 1-3.
Reposition label and check the read rate
(<C> command).
Try a label that is known to be readable.
Shield the bar code and/or scan head to
verify that excessive light is not the prob-
lem.
Remedy by remounting, eliminating
interference, or shielding.
Many object detectors emit pulsed infra-
red signals that can seriously degrade the
read rate if they shine into the scanner or
onto the bar code label when it is being
read.
