Problems While Scanning Bar Codes

Problem
You cannot see a red beam of light from
the scanner when you press the Scan
button and aim the scanner at a bar code
label.
When you release the Scan button or
handle trigger, the Good Read light does
not turn off.
You have an input device attached to the
CK30 and it cannot read any bar codes.
The input device attached to the
computer does not appear to work well
or read bar code labels very quickly.
Your 1551E or 1553 scanner was
working fine, but after changing the port
setting you cannot change the
configuration.

• If the CK30 is in a communications dock, make sure that the
communications dock is connected to the serial device using
the appropriate cable.
For more information on using the serial port, see "Configuring
Serial Communications" on page 44.
Solution
There are two possible problems:
• You may be too far away from the bar code label.
Try moving closer to the bar code label and scan it
again.
• You may be scanning the bar code label "straight
on." Change the scanning angle and try again.
You can test the effective range of the scanner. Move
within 2 feet of a wall and test the scanner. You need to
be within the scanning range to scan bar code labels.
For help scanning bar codes, see "Scanning Bar Codes"
on page 22.
The Good Read light will remain on if you configure
the CK30 to use continuous/edge triggering. If you
configure the CK30 for level triggering and the Good
Read light remains on, there may be a problem. Press
the Scan button or pull the trigger again without
scanning a bar code label. If the light is still on, contact
your local Intermec service representative.
You may not be using an input device that is supported
with the CK30. Make sure you are using one of the
supported input devices and that you have selected the
correct scanner model using the Configuration Utility.
See page 25 for a list of supported input devices.
Try setting the Scanner Model command to the
specific input device you have attached. Check the bar
code symbologies you have enabled on the CK30.
Enable only the symbologies that you are using.
The 1551E or 1553 scanner must be using the correct
RS-232 settings to allow configuration from the
Configuration Utility. Try disabling and then enabling
the scanner port state.
