Accessing Diagnostic Modes
To use the different modes available in Service
Diagnostics, you must have lower DIP switch 3 turned
on and the display reads 000.
From the 000 display, press Feed and Clear at the
same time until you see 001 (data dump mode),
002 (serial loop back test), or
003 (parallel port test). Each mode is activated by
pressing Pause.
Data Dump Mode
To use data dump mode:
1. Set lower DIP switch 3 to ON. The display reads
000.
2. Press Feed and Clear at the same time. The
display changes to 001 (Mode 1).
3. Press Pause to enter data dump mode. Two
blank labels feed and the display reads 111.
4. Download the data stream you want to dump (print
on a label).
5. Press Feed and Clear at the same time to exit
data dump mode. The display reads 000.
Data dump mode captures all data being sent to the
printer and holds it in a buffer. No data is acted upon
(ex: Immediate commands or Job request packets).
Once the buffer is full, a label automatically prints with
the downloaded data printed on it. You must press
Feed to print a label if the amount of data sent does
not fill the buffer to the required level.
NOTE: If you are sending data down through
SENDFILE, be sure to disable ENQ. This
