A798-PG00001C
Chapter 2: Diagnostics and Conguration
The A798 printer performs a number of diagnostics that provide useful information about the operating status of the
printer. The following diagnostic tests are available.
Start-up diagnostics
Performed during the printers start-up cycle.
Runtime diagnostics
Performed during normal printer operation.
Remote diagnostics
Maintained during normal operation and reported in the print test.
The printer can be congured with the following settings and functions through the conguration menu that is printed
on the receipt. For more information on conguring the printer, see “Printer conguration” on page 16.

Start-up Diagnostics
When the printer receives power or performs a hardware reset, it automatically performs the startup diagnostics (also
known as level 0 diagnostics) during the start-up cycle. The following diagnostics are performed:
Turn off motors
Perform boot CRC check of the rmware ROM, test external SRAM, test EEPROM, and test main program CRC
Failure causes Start-up Diagnostics to stop; the printer beeps and the LED ashes a set number of times, indicating the
nature of the failure. The table in the “Indicators” section (page 14) describes the specic tone and LED sequences.
Check if paper is present
Return the knife to the home position
Failure causes a fault condition. The table in the “Indicators” section (page 14) describes the specic tone and LED
sequences.
Check if receipt cover is closed
Failure does not interrupt the start-up cycle.
When the start-up diagnostics are complete, the printer makes a two-tone beep (low then high frequency), the paper feed
button is enabled, and the printer is ready for normal operation.
If the printer has not been turned on before, or a new EEPROM has been installed, the default values for the printer
functions will be loaded into the EEPROM during start-up diagnostics.
