12 Chapter 2: Diagnostics and Configuration

Runtime diagnostics

Runtime diagnostics (sometimes called level 2 diagnostics) run during normal printer operation. When the following
conditions occur, the printer automatically turns off 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 LED 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 flash cycles
• Number of cutter jams
• Number of times the cover is opened
• Number of barcodes printed
• Number of receipt characters printed
• Number of printer faults
• Maximum temperature reached
• Number of dots printed
• Number of dots printed on current printhead
• Number of printhead changes
• Number of receipt mechanism changes
• Number of knife mechanism changes
• Number of black mark errors
• Number of thermistor errors
• Number of low voltage errors
• Number of high voltage errors
• Number of firmware starts
• Number of EEPROM updates
