3.2. Initialize Unit

 

If the SetUp Switch configuration is changed, the unit must be initialized before new switch settings will take effect. To initialize the PSU, proceed as follows:

1                     Press and hold the PAUSE and TOF buttons, briefly press the CLEAR Button, and then release all three buttons. The PSU will perform a RAM test, then initialize itself according to SetUp Switch settings.

2                     During the test, all indicators will light. The test will require about 8 seconds for each 256K of RAM memory.

3                     If the memory test determines that RAM memory is O.K., the PSU will send a test message to the printer. This message lists current SetUp Switch selections. If the memory test detects an error, all three STATUS indicators will blink. If this occurs, please contact WTI Customer Service as described in Appendix G.

4                     To initialize the unit without performing the memory test, press and hold PAUSE, TOF, and CLEAR, release the three buttons, and then immediately press CLEAR again.
