Table 8. Message List
Explanation
The validator has detected that
it needs calibration. This
message is a reminder and
does not halt printing.
Run Calibrate procedure was
attempted with Peel-Off Media
Handling selected.
NOTE: You can perform Auto
Calibrate in Peel-Off
mode if Cal in Peel
Mode = Enable. Be
prepared to catch
labels during the
calibrate procedure.
The bar code data fails the
checksum check or is missing
the checksum digit.
The program successfully
loaded into printer RAM and the
checksum matched. The old
program is now being deleted
from flash memory.
Data validation error: the
contrast between bars and
spaces is not sufficient. This
can be caused by too little heat
in the thermal transfer or by use
of colored media or ribbons.
Solution
Press PAUSE to clear the
message. Calibrate the
validator. See "Calibration" on
page 295.
1. Select another Media
Handling option in the
QUICK SETUP or MEDIA
CONTROL menu.
2. Enable Cal in Peel Mode in
the CALIBRATE CTRL
menu.
NOTE: Admin User must =
Enable.
Verify that the checksum digit
exists in the bar code and that it
is the correct value.
No action required.
Increase Print Intensity or
reduce Print Speed in the
QUICK SETUP menu or via
host software, change media, or
disable Symbol Contrast in the
VALIDATOR menu.
