Communications Diagnostics
If there’s a problem transferring data between the computer and
the printer, try putting the printer in the Communications Diagnos-
tics Mode (also referred to as the “DUMP” mode). The printer will
print the ASCII characters and their and their text representation
(or the period ‘.’, if not a printable character) for any data received
from the host computer
To enter Communications Diagnostics Mode:
1. Print a configuration label as described on pg. 34.
5. At the end of 2nd diagnostics report, the printer will print:
“Press FEED key to enter DUMP mode”.
6. Press the FEED key. The printer will print: “Entering DUMP
mode”.
Note: If the FEED key is not pressed within 3 seconds, the printer will print “DUMP
mode not entered” and will resume normal operation.
7. At this point, the printer is in DUMP mode and will print the
ASCII hex codes of any data sent to it, and their text repre-
sentation (or “.” if not a printable character).
Additionally, a file with a “.dmp” extension containing the ASCII
information will be created and stored in the printer’s memory. It
can be viewed, “cloned” or deleted using the Label Vista applica-
tion. (Refer the Label Vista documentation for more information.)
To terminate the Communications Diagnostics Mode and return
the printer to normal operations:
1. Turn the printer OFF.
2. Wait 5 seconds.
3. Turn the printer ON.
