4.1.2. RAM Test - Initialize Unit

 

Pressing and holding in the PAUSE and TOF button, while tapping the CLEAR button performs a test on RAM and initializes the SetUp switch settings.

All indicators will light during the test. About eight seconds is required for each 256K of installed memory.

When memory tests good, a test message with your default SetUp switch settings is sent to the printer. If a memory Write/Read error is detected, the three STATUS indicators will blink. If this occurs, please contact WTI Customer Service.

Note:

You must initialize the DIP switch settings each time you change them.

If you wish to just initialize the settings and bypass the memory test, use the three-button combination described above, then immediately tap the CLEAR button.
