Resetting the CK3
You seldom need to reset the CK3. However, you do need to reset the
CK3 when an application is locked up and does not respond, when
you upgrade the firmware, or when you reflash the CK3. The CK3
uses the configuration currently saved in flash memory during the
reset process. There are three ways to reset the CK3:
• Warm boot
• Cold boot
The scanner does not
read the bar code
label.
• Aim the scanning beam so that it crosses the entire
bar code label in one pass. Try changing the scan
angle.
• Check the quality of the bar code label, Scan a bar
code label that you know scans well. Compare the
two bar code labels to see if the bar code quality is
too low. You may need to replace the label that you
cannot scan.
• Make sure the bar code symbology is enabled. For
help, see “Configuring the CK3 With Intermec
Settings” on page 29.
• Make sure the application is accepting input by
scanning a bar code. You may need to type this
information instead.
The scanner does not
read the bar code
labels quickly, or the
scanning beam
seems to be faint or
obscured.
The scanner window may be dirty. Clean the window
with a solution of ammonia and water. Wipe dry. Do
not allow abrasive material to touch the window.
The scanned bar
code data that
appears in your
application does not
match the data
encoded in the bar
code label.
The CK3 may have decoded the bar code label in a
different bar code symbology. Try scanning the bar
code label again. Make sure you scan the entire label.
