Message
Unscannable:
xx Missing Codes
Table 6. Message List
Explanation
Data validation error: missing
bar code. An expected bar
code is missing or was printed
so poorly that the validator
cannot detect it.
xx = number of bar codes
missing on the form that
caused the error.
Solution
1. Check that paper and
ribbon are clean,
unwrinkled, and installed
correctly.
2. Run a print job and check
that the validator beam is
not obstructed; remove
obstructions as
necessary.
3. Run a print job and check
that the READ LED
flashes as bar codes exit
the printer. If the READ
LED does not flash, cycle
power and run the job
again. If the READ LED
does not flash, inspect the
cables and the cable
connections. If the cables
are undamaged and the
connections are good,
replace the validator.
4. If using bitmapped bar
codes, set Number of
Codes (page 52) to the
number of codes per form
(not Auto).
5. Adjust Print Intensity and
Print Speed in the QUICK
SETUP menu or via host
software.
