Startup (Level 0) Diagnostics

The printer automatically performs startup diagnostics during the startup cycle when power is supplied or when the printer goes online. Startup diagnostics comprise the following actions:

  1. Power off the printer.
  2. Perform CRC check of the firmware ROM, read external RAM.
    Note

    Failure causes startup diagnostics to stop.

  3. EEPROM check
    Note

    Failure causes startup diagnostics to stop.

  4. Printer Status (Amber) LED is turned on.
  5. Check if paper is present.
  6. Return the knife to the home position.
    Note

    Failure causes a fault condition.

  7. Check if printer Top Cover/Printer Door is closed.
    Note

    Failure causes turning on the Printer Status (Amber) LED until the Top Cover/Printer Door is closed.

When the last step is complete, the Paper Feed button is enabled and the printer is ready for normal operation. Information about the test is available in the communication interface through the commands.

If the printer has not been turned on or a new EEPROM has been installed, the default values for the printer functions (set in Level 1 Diagnostics) are loaded into the EEPROM during startup diagnostics. . For more information, refer to Configuring the Printer. If the EEPROM load has failed, the Printer Status LED is turned on.
