Using the Printer
Printing a Self-Test Label
Printing a self-test label checks the printer overall operability. To run
a self-test, confirm that the printer is loaded and connected to AC
power and no print jobs are in process. Then:
1. Turn off the power.
2. Press and hold the FEED button.
3. Turn on the power.
4. After the printer starts printing release the FEED button.
5. After the self-test label finishes printing, the printer will enter the
hex dump mode. To return to normal operation you must cycle
printer power.
Important!
The printer will be in hex dump mode after printing the self-
test label. It cannot print normal labels in hex dump mode.
The printer will return to normal operation only when you
cycle printer power.
