Chapter 2: Printer Status, Ethernet and Indicators
The A760 printer performs a number of diagnostics that provide useful information about the
operating status of the printer. The following diagnostic tests are available. See page 12 and 13 for
more information.
• Startup diagnostics
Performed during the printer’s startup cycle.
• Runtime diagnostics
Performed during normal printer operation.
• Remote diagnostics
Maintained during normal operation and reported in
the print test.
• The printer can be configured with the following
settings and functions through the configuration menu
that is printed on the receipt. For more information on
configuring the printer, see A760 User Guide “Printer
configuration” page 30

Startup 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 startup cycle. The following
diagnostics are performed:
• Turn off motors
• Perform boot CRC check of the firmware ROM, test
external SRAM, test EEPROM, and test main program
CRC
Failure causes Startup Diagnostics to stop; the
printer beeps and the LED flashes a set number of
times, indicating the nature of the failure. The table
in the “Indicators” section (page 16) describes the
specific 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 16) describes the specific
tone and LED sequences.
• Check if receipt cover is closed
Failure does not interrupt the startup cycle.
When the startup 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 startup diagnostics.
