Chapter 2: Printer Status and Indicators
The A776/B780 printer performs a number of diagnostics that provide useful information about the operating status of
the printer. The following diagnostic tests are available.
• Startupdiagnostics,performedduringstartupcycle.
• Runtimediagnostics,performedduringnormal
printer operation.
• Remotediagnostics,run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. To learn more see the section
called “Conguring the Printer” in the A776/B780 User
Guide, page 26.

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omotorsandsolenoids
• PerformbootCRCcheckofthermwareROM,test
external SRAM, test EEPROM, and test main program
CRC
Failure causes Startup Diagnostics to stop; the
printer beeps and the light ashes a set number of
times, indicating the nature of the failure. The table
in the “Indicators” section (page 16) describes the
specic tone and light 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 specic
tone and light 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.
Runtime diagnostics
Runtime diagnostics (sometimes called level 2
diagnostics) run during normal printer operation. When
the following conditions occur, the printer automatically
turns o the appropriate motors and disables printing to
prevent damage to the printer:
• Paper out
• Receiptcoveropen
• Knifeunabletohome
• Printhead too hot
• Voltagesoutofrange
The light on the operator panel will signal when these
conditions occur as well as indicate what state or mode
the printer is in.
Remote diagnostics
Remote diagnostics (sometimes called level 3
diagnostics) keeps track of the following tallies and
prints them on the receipt during the print test. See the
sample test printout on the next page. These tallies can
be used to determine the printer’s state of health.
• Modelnumber
• Serialnumber
• CRCnumber
• Numberoflinesprinted
• Numberofknifecuts
• Numberofhourstheprinterhasbeenon
• Numberofashcycles
• Numberofcutterjams
• Numberoftimesthecoverisopened
• Maximumtemperaturereached
