DUMP mode.”

4. 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 
representation (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 application. (Refer the Label Vista documentation for 
more information.)

turn the printer to normal operations:

1. Turn the printer OFF.
2. Wait 5 seconds.
3. Turn the printer ON.

pendix D of this manual.  You will need to supply the following 
information:

•  Unit serial number (14 digit number, including dashes)  

The serial number is found on the large label on the back 
of the printer.  It is also reported in the configuration label 
printout.  (Refer to Figures 23 through 23b.)

•  Product Configuration Code (PCC) (15 digit number, in-

cluding dashes).  The PCC number for an RW 420 Printer 
will begin with “RW4” and is printed above the unit serial 
number on the back of the unit.
