Chapter 5. Troubleshooting
The printer uses a combination of LED lights to display a
variety of printer states. See the "Problems and Solutions"
section for those requiring further actions.
When an error occurs that you cannot clear, print a test label
before calling Service or sending the printer in for repair.
Printing a Test Label ––––––––––––––––––––––––––––––––––––––––
c
Turn the printer off and disconnect the host from the printer
before printing a test label. While printing the test label, the
printer sends a character string to the communications port.
This could cause problems at the host.
Before you call for service, print a test label. The label
contains information to help Service diagnose mechanical and
setup problems. To print a test label, hold the trigger down
and turn the printer on. The LED remains off for 1 second,
turns amber for 2 seconds, and then turns off again. Release
the trigger as soon as the amber LED turns off.
If the printer is in On-demand mode, the LED rapidly blinks
green. Press the trigger to dispense the test label. If the
printer is in Continuous mode, a test label prints automatically.
