To reset the 

PSII

 configuration parameters to the factory defaults, press the 

Test

 button and 

hold it in while turning the printer power on. Keep the test button pressed until the Status 
Indicator light turns green, then release the test button. After approximately 20 seconds, a 
configuration label prints automatically.

A bi-color Status Indicator displays the operational status of the 

PSII

. The following 

conditions might occur:

• During normal operation, the LED is solid green for more than 30 seconds. This indicates 

all the hardware is functioning properly and it has detected the presence of the network. It 
does not mean the 

PSII

 has an IP address or is attached to a printer queue.

• If the LED is rapidly flashing green (9 times/sec), the 

PSII

 has not detected the presence of 

a network cable. To solve the problem:

•

Turn the printer power off. Remove the network cable from the 

PSII

. Plug the 

network cable back in until you hear a positive click. Check the other end of the cable 
in the same manner. Turn the printer power on. If the 

PSII

 still does not detect a cable, 

continue.

•

Verify that the network cable is 10BASE-T and has an RJ-45 connector. 

•

Connect the 

PSII

 to a network drop that is a known good network connection. If the 

PSII

 is still unable to detect the network cable, contact Technical Support for 

assistance.

• If the LED is slowly flashing green (1 time/sec), the 

PSII

 is trying to print a job. If the job 

does not print, check the following:

•

Verify that the printer has media and ribbon (if in thermal transfer mode). If the 
printer is showing any errors, it is unlikely that the 

PSII

 can send data to the printer. 

The LED continues to blink until the printer malfunction is resolved or until the 
printer is turned off.

•

Flashing red indicates the Power On Self Test (POST) is in progress.

• If the LED is solid red for more than 30 seconds, the 

PSII

 has failed the POST. If the 

failure is not severe, the 

PSII

 attempts to print a configuration label on the printer. A failed 

POST can be caused by any of the following:

•

The printer attached to the 

PSII

 device is malfunctioning. Turn the printer power off, 

wait 10 seconds, then turn the printer back on. 

•

If the 

PSII

 still fails the POST, continue below. The 

PSII

 has a hardware problem that 

can be fixed only by replacing or returning the unit. Contact Technical Support for 
repair or replacement information.

Cables with a rating higher than CAT-5 have not been tested.
